[0064] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0065] 1. SSB

[0066] A synchronization signal and physical broadcast channel (SSB) can include a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH) distributed on four consecutive orthogonal frequency division multiplex (OFDM) symbols. Referring to the SSB timing structure diagram shown in Figure 2, an SSB burst set period includes multiple SSBs (for example, 8 SSBs), and different SSBs can correspond to different beam directions. The SSB burst set period supported by NR is 5 milliseconds (ms), 10ms, 20ms, etc.

[0067] 2. NE paging

[0068] The main function of paging is to enable network equipment to page the terminal device (UE) through a paging message when the terminal device is in the Radio Resource Control (RRC) idle state or the RRC inactive state, or to notify the UE of system information changes, earthquake and tsunami, public warning information, etc. through a short message. It should be noted that the above messages also apply to the UE's RRC connected state.

[0069] Paging includes the Physical Downlink Control Channel (PDCCH) scrambled by the Paging Radio Network Temporary Identifier (P-RNTI) and the Physical Downlink Share Channel (PDSCH) scheduled by the PDCCH. For example, a paging message can be transmitted on the PDSCH, and a short message can be 8 bits in the PDCCH.

[0070] For a UE in the RRC_IDLE state or the RRC_INACTIVE state, since there is no other data communication between the UE and the network device, in order to reduce the UE's power consumption, such as power loss, the UE can monitor the paging channel discontinuously, that is, adopt the Paging discontinuous reception (DRX) mechanism. Under the Paging DRX mechanism, the UE only needs to monitor paging during one paging occasion (PO) in each DRX cycle. PO is a series of PDCCH monitoring occasions (PMO) and can be composed of multiple time slots. In addition, a paging frame (PF) is a radio frame (10ms) that can include multiple POs or the starting positions of multiple POs.

[0071] The Paging DRX cycle can be determined by the common cycle in the system broadcast and the dedicated cycle configured in the high-level signaling such as the Non-Access Stratum (NAS) signaling. The UE can take the minimum cycle of the common cycle and the dedicated cycle as the paging cycle. From the network perspective, a Paging DRX cycle can include multiple POs. The location where the UE monitors the PO is related to the device identity (IDentity, ID) of the UE. For example, the PF and PO of a UE in a Paging DRX are determined as follows:

[0072] The system frame number (SFN) of the radio frame PF can be determined by the following formula (1): (SFN+PF_offset) mod T = (T div N) * (UE_ID mod N) (1)

[0073] The number or index Index(i_s) of the paging occasion PO within a PF is determined by the following formula (2): i_s=floor(UE_ID / N)mod Ns (1)

[0074] Where T is the duration of the DRX cycle during which the UE receives paging. The network device broadcasts a default DRX cycle. If a UE-specific DRX cycle is configured for the UE via RRC / higher layer signaling, the minimum of the DRX cycle broadcast by the network device and the UE-specific DRX cycle configured via RRC / higher layer signaling is used as the UE's DRX cycle. If a UE-specific DRX cycle is not configured for the UE via RRC / higher layer signaling, the DRX cycle broadcast by the network device is used as the UE's DRX cycle.

[0075] Among them, N is the number of radio frames PF that can be used to receive paging messages in a non-continuous DRX cycle of the UE; Ns is the number of POs included in a PF; PF_offset is a time domain offset used to determine the PF; UE_ID is the device identifier of the UE, and the device identifier of the UE can be determined by 5G-S-TMSI mod 1024.

[0076] In the above formulas (1) and (2), div is the integer division operation (taking the quotient), mod is the modulo operation (taking the remainder), and the floor() function is "rounding down".

[0077] For a certain UE, the position of the PF and the index of the PO in a Paging DRX cycle can be obtained according to the above formulas (1) and (2). A PO can be composed of multiple PDCCH monitoring opportunities. For example, a PO includes multiple PDCCH monitoring opportunities, and the number of multiple PDCCH monitoring opportunities is equal to the number of SSBs broadcast by the network device.

[0078] After the UE obtains the PF position, the PO index, and the number of PDCCH monitoring opportunities in the PO, it can use the relevant configuration parameters to determine the starting position of the first PDCCH monitoring opportunity in the PO. This starting position can be configured through higher-layer signaling or obtained based on the PO index. The UE can blindly detect the Paging message based on the determined PO.

[0079] From the above, it can be seen that the UE determines the listening opportunity PO. It can be seen that the determination of the listening opportunity PO is related to the device identification UE ID of the terminal device, the number of radio frames PF in a DRX cycle, and the number of listening opportunities PO in a PF. If there are many UEs in the communication system and the network device cannot assign each UE to a different PO, there will be a situation where multiple UEs correspond to one PO. If the network device needs to page (Paging) a UE on this PO, the network device will repeatedly send the P-RNTI-scrambled PDCCH at S consecutive PDCCH listening opportunities corresponding to this PO, where S is the number of SSBs sent by the network device. In other words, the network device will traverse each SSB corresponding to this PO and repeatedly send the P-RNTI-scrambled PDCCH. In this way, all UEs mapped to this PO will receive the P-RNTI-scrambled PDCCH and the PDSCH indicated by the PDCCH. For example, with reference to Figure 3, UE1 monitors all PDCCH listening opportunities (PMO) corresponding to PO1, and receives the paging indication information PDCCH corresponding to SSB3.

[0080] 3. Smart Surfaces

[0081] For example, Large Intelligent Surfaces (LIS) or Reconfigurable Intelligent Surfaces (RIS) are emerging artificial material devices.

[0082] Smart surfaces are an emerging artificial material technology. Several related terms refer to similar technologies or entities, including: Large Intelligent Surface (LIS), Smart Reflect Array (SRA), Reconfigurable Reflect Array (RRA), Intelligent Reflecting Surface (IRS), and Reconfigurable Intelligent Surfaces (RIS). For simplicity, RIS will be used in the following discussion.

[0083] RIS devices can dynamically or semi-statically change their electromagnetic properties, affecting the reflection and refraction of electromagnetic waves incident on them. By manipulating the reflected and refracted electromagnetic waves, RIS devices implement beam scanning and beamforming functions. As can be understood, RIS devices use a simulated beam forwarding method to forward downlink signals from network devices to terminal devices, and conversely, forward uplink signals from terminal devices to network devices.

[0084] Thanks to the fact that RIS devices do not require RF and baseband processing circuits, they have the advantages of lower cost and implementation complexity, lower power consumption, thin thickness, light weight, no introduction of additional receiving-end thermal noise, and flexible deployment compared to traditional wireless communication transceiver equipment.

[0085] Future wireless networks may deploy a large number of RIS devices to replace the dense deployment of base stations. For example, RIS devices can be used to forward signals from network devices (such as SSB or CSI-RS) to enhance coverage. However, after the introduction of RIS devices, the beams formed by the signals forwarded by the RIS devices may differ from the beams originally configured by the network devices without the RIS devices. Therefore, in implementation scenarios with multiple beam sets, terminal devices receiving different beam sets will cause confusion in determining paging resources, thereby affecting the accuracy of paging.

[0086] In some scenarios, the terminal device UE and the network device are blocked by obstacles, resulting in poor channel transmission quality between the terminal device UE and the network device. At this time, the UE can communicate with the network device through an intelligent surface device such as a RIS device, thereby improving the transmission quality. For the UE that communicates directly with the network device and the UE that communicates with the network device through the RIS device, the SSB set corresponding to one paging occasion PO is different. Referring to Figure 4, for the UE that communicates directly with the network device, the SSB set corresponding to one paging occasion PO is {SSB1, SSB2, SSB3}, and for the UE that communicates with the network device through the RIS device, the SSB set corresponding to one paging occasion PO is {Beam1, Beam2, Beam3}. In this way, in an implementation scenario where there are two or more beam sets, the terminal device receives different beam sets, which will cause confusion in the terminal device's determination of paging resources, thereby affecting the accuracy of paging.

[0087] Based on this, an embodiment of the present application provides a paging method, in which, when the first device reflects or refracts the signal transmitted between the network device and the terminal device, the terminal device can receive paging configuration information sent by the network device, wherein the paging configuration information is used to indicate the first spatial information set or the second spatial information set; the terminal device determines the paging resources based on the paging configuration information, wherein the paging resources are the paging resources corresponding to the first spatial information set, the second spatial information set or the third spatial information set; wherein the first spatial information set is all or part of the union of the second spatial information set and the third spatial information set; the third spatial information set is the spatial information set broadcast by the network device; and the second spatial information set is the spatial information set of the first device. That is to say, when the network device and the terminal device communicate through the first device, the terminal device can determine the paging resources corresponding to the indicated spatial information set for paging monitoring based on the spatial information set indicated by the paging configuration information sent by the network device to the terminal device; in this way, after the introduction of the smart surface device, the terminal device can determine that the network device and the terminal device establish a communication link through the smart surface device based on the paging configuration information sent by the network device to indicate the first spatial information set or the second spatial information set. Furthermore, the terminal device uses the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the quality of communication transmission while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0088] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0089] FIG5 shows a paging method provided by an embodiment of the present application, which is applied to a terminal device. The method may include:

[0090] Step 510: When the first device reflects or refracts a signal transmitted between the network device and the terminal device, the terminal device receives paging configuration information sent by the network device, where the paging configuration information is used to indicate the first spatial information set or the second spatial information set;

[0091] Step 520: The terminal device determines the paging resources based on the paging configuration information, where the paging resources are the paging resources corresponding to the first spatial information set, the second spatial information set, or the third spatial information set; the first spatial information set is all or part of the union of the second spatial information set and the third spatial information set; the third spatial information set is the spatial information set broadcast by the network device; and the second spatial information set is the spatial information set of the first device.

[0092] In an embodiment of the present application, the spatial information in the spatial information set may be beam information corresponding to the paging resource. The spatial information set may be any one of an SSB set, a channel state reference signal (CSI-RS) resource set, a channel sounding reference signal (SRS) resource set, a transmission configuration indication (TCI) state set, a unified TCI state set, a downlink spatial relation filter set, an uplink spatial relation filter set, and a quasi co-location (QCL) relationship.

[0093] Here, paging includes the PDCCH scrambled by the P-RNTI and the PDSCH scheduled by the PDCCH. When the terminal device is in the RRC idle state or inactive state, the network device can page the terminal device via a paging message, or notify the terminal device of information such as message changes, earthquakes, tsunamis, and public warnings via a short message. In one implementation, the paging message can be transmitted in the PDSCH, and the short message can be 8 bits in the PDCCH.

[0094] In the embodiment of the present application, the paging configuration information is used to indicate information of the first spatial information set or the second spatial information set. Of course, the paging configuration information may also indicate the third spatial information set.

[0095] In the embodiment of the present application, the third spatial information set may be a spatial information set broadcast by the network device. Here, the spatial information set broadcast by the network device may be a spatial information set configured by the high-layer parameter ssb-PositionsInBurst in the system information block SIB1.

[0096] In the embodiment of the present application, the first device may be a smart surface device, such as a RIS device. It should be noted that the first device may implement signal forwarding between the terminal device and the network device.

[0097] Here, the spatial information set of the first device can be understood as a spatial information set supported by the first device or a spatial information set associated with the first device. The first device is used to forward signals sent by a network device to a terminal device, or to forward signals sent by a terminal device to a network device. Forwarding includes reflection or refraction, thereby changing the direction of signal transmission.

[0098] It is understood that the signal can be information carried on an uplink channel sent by a network device (forwarded by the first device) to a terminal device, that is, the signal can be an uplink reference signal; the signal can also be information carried on a downlink channel sent by a terminal device (forwarded by the first device) to a network device, that is, the signal can be a downlink reference signal. It should be noted that the spatial information set belongs to the downlink reference signal.

[0099] It is understandable that the network device may directly send the third spatial information set to the terminal device; of course, the network device may also forward the second spatial information set to the terminal device through the first device.

[0100] It should be noted that, for a terminal device that communicates directly with a network device, the spatial information set corresponding to a paging occasion PO may be the third spatial information set broadcast by the network device; for a terminal device that communicates with the network device through a first device, the spatial information set corresponding to a paging occasion PO may be the second spatial information set, or the first spatial information set, that is, all or part of the union of the second spatial information set and the third spatial information set.

[0101] In the embodiment of the present application, the first spatial information set is the entirety of the union of the second spatial information set and the third spatial information set, which may mean that the first spatial information set includes the spatial information in the second spatial information set and the spatial information in the third spatial information set.

[0102] In the embodiment of the present application, the first spatial information set is a part of the union of the second spatial information set and the third spatial information set, which may mean that the first spatial information set includes part of the spatial information in the second spatial information set, or the first spatial information set includes part of the spatial information in the third spatial information set, or the first spatial information set includes part of the spatial information in the second spatial information set and part of the spatial information in the third spatial information set. This application does not impose any specific restrictions on this.

[0103] It should be noted that the first spatial information set, the second spatial information set, and the third spatial information set are not completely identical. For example, the spatial information contained in the first spatial information set, the second spatial information set, and the third spatial information set is not completely identical. For example, the amount of spatial information contained in the first spatial information set, the second spatial information set, and the third spatial information set is not completely identical, and / or the signals corresponding to the spatial information contained in the first spatial information set, the second spatial information set, and the third spatial information set are not completely identical.

[0104] In the embodiment of the present application, the spatial information set corresponding to one paging occasion PO may be the first spatial information set, the second spatial information set, or the third spatial information set.

[0105] In the embodiment of the present application, the paging resource may be a paging resource corresponding to a spatial information set corresponding to a paging occasion PO, that is, the paging resource may be a paging resource corresponding to one of the first spatial information set, the second spatial information set, and the third spatial information set. It should be noted that the paging resource may be configured by the network device and may be included in the paging configuration information. Of course, the paging resource may also be configured by other signaling. This application does not impose specific limitations on this.

[0106] It can be understood that in an embodiment of the present application, the network device and the terminal device can communicate directly, and the network device and the terminal device can also communicate through the first device. When the network device and the terminal device communicate through the first device, the terminal device receives paging configuration information from the network device for indicating the first spatial information set or the second spatial information set, and determines the paging resources based on the spatial information set indicated by the paging configuration information. In this way, after determining the paging resources, the terminal device uses the paging resources to monitor the P-RNTI-encrypted PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information in the indicated spatial information set, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information in the indicated spatial information set. In this way, after the introduction of the smart surface device, the terminal device can determine that the network device and the terminal device establish a communication link through the smart surface device based on the paging configuration information sent by the network device to indicate the first spatial information set or the second spatial information set. Furthermore, the terminal device uses the communication link to enable itself to monitor paging at the appropriate time, thereby improving the quality of communication transmission while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0107] In some embodiments, the first spatial information set is the entirety of the union of the second spatial information set and the third spatial information set, which may include: the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the second spatial information set, and / or the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the third spatial information set.

[0108] In the embodiment of the present application, since the first spatial information set is the entirety of the union of the second and third spatial information sets, the first spatial information set can include both the second and third spatial information sets. Generally, the second and third spatial information sets are not empty. Therefore, if the first spatial information set includes the second spatial information set, the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the second spatial information set; and if the first spatial information set includes the third spatial information set, the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the third spatial information set.

[0109] In some embodiments, the first spatial information set is all or part of the union of the second spatial information set and the third spatial information set, which may include: the amount of spatial information in the first spatial information set is equal to or less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0110] It should be noted that the second spatial information set and the third spatial information set are not completely identical, that is, the spatial information in the second spatial information set is completely different from the spatial information in the third spatial information set, and there is some commonality between the spatial information in the second spatial information set and the spatial information in the third spatial information set. When the first spatial information set is all or part of the union of the second spatial information set, the relationship between the amount of spatial information in the first spatial information set and the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set includes:

[0111] In the case where the first spatial information set is the entire union of the second spatial information set, if the spatial information in the second spatial information set and the spatial information in the third spatial information set are completely different, then the amount of spatial information in the first spatial information set is equal to the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0112] In a case where the first spatial information set is the entirety of the union of the second spatial information set, if the spatial information in the second spatial information set and the spatial information in the third spatial information set are not completely identical, the amount of spatial information in the first spatial information set is less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0113] In the case where the first spatial information set is part of the union of the second spatial information set, regardless of whether the spatial information in the second spatial information set and the spatial information in the third spatial information set are completely different or not completely different, the amount of spatial information in the first spatial information set is less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0114] In some embodiments, different spatial information sets correspond to different paging resources, and the different spatial information sets include one or more of the following: a first spatial information set, a second spatial information set, and a third spatial information set. Different spatial information sets corresponding to different paging resources include: the first spatial information set corresponding to a first paging resource, the second spatial information set corresponding to a second paging resource, and the third spatial information set corresponding to a third paging resource.

[0115] In an embodiment of the present application, the first paging resource can be used by the terminal device to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information in the first spatial information set under the paging occasion PO, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information in the first spatial information set. Exemplarily, if the number of spatial information included in the first spatial information set is Y, the P-RNTI-scrambled PDCCH is monitored at Y' PDCCH monitoring opportunities corresponding to Y spatial information; wherein Y and Y' may be the same, or Y and Y' may be different. It should be noted that, when each spatial information is configured to correspond to X PDCCH monitoring opportunities in the paging occasion PO, if X=1, then Y and Y' are the same; if X>1, then Y and Y' are different, and the relationship between Y and Y' is Y'=Y×X.

[0116] In an embodiment of the present application, the second paging resource can be used by the terminal device to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information included in the second spatial information set under the paging occasion PO, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information in the second spatial information set. Exemplarily, if the number of spatial information included in the second spatial information set is P, the P-RNTI-scrambled PDCCH is monitored at P' PDCCH monitoring opportunities corresponding to P spatial information; wherein P and P' can be the same, or P and P' can be different. It should be noted that, when each spatial information is configured to correspond to X PDCCH monitoring opportunities in the paging occasion PO, if X=1, then P and P' are the same; if X>1, then P and P' are different, and the relationship between P and P' is P'=P×X.

[0117] In an embodiment of the present application, the third paging resource can be used by the terminal device to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information included in the third spatial information set under the paging occasion PO, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information in the third spatial information set. Exemplarily, if the number of spatial information included in the third spatial information set is S, the P-RNTI-scrambled PDCCH is monitored at S' PDCCH monitoring opportunities corresponding to the S spatial information; wherein S and S' may be the same, and P and P' may be different. It should be noted that, when each spatial information is configured to correspond to X PDCCH monitoring opportunities in the paging occasion PO, if X=1, then S is the same as S'; if X>1, then S is different from S', and the relationship between S and S' is S'=S×X.

[0118] In some embodiments, the first paging resource, the second paging resource, and the third paging resource satisfy at least one of the following:

[0119] The first paging resource includes a second paging resource and a third paging resource;

[0120] The PDCCH monitoring opportunities corresponding to the second paging resource and the third paging resource do not overlap in the time domain;

[0121] The PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the time domain;

[0122] The PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the frequency domain;

[0123] The first paging resource, the second paging resource, and the third paging resource are scrambled and indicated using different paging radio network temporary identifiers P-RNTIs.

[0124] In the embodiment of the present application, since the first spatial information set may include the second spatial information set and the third spatial information set, the first paging resource corresponding to the first spatial information set may include the second paging resource corresponding to the second spatial information set and the third paging resource corresponding to the third spatial information set.

[0125] In the embodiment of the present application, by distinguishing time domain resources, the PDCCH monitoring opportunities corresponding to the second paging resource and the third paging resource do not overlap in the time domain.

[0126] In the embodiment of the present application, time domain resources are distinguished, that is, the PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the time domain.

[0127] In the embodiment of the present application, frequency domain resources are distinguished, that is, the PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the frequency domain.

[0128] In an embodiment of the present application, different P-RNTIs can be used to distinguish the first paging resource, the second paging resource, and the third paging resource, that is, the first paging resource, the second paging resource, and the third paging resource are respectively indicated using different P-RNTI scrambling, so that the terminal device monitors the PDCCH scrambled by the P-RNTI corresponding to the paging resource within the PO.

[0129] In some embodiments, the configuration of the first spatial information set and the second spatial information set may be achieved as follows:

[0130] The configuration of the first spatial information set is that the network device configures a first number of physical downlink control channel PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the first number is associated with the number of actually transmitted spatial information contained in the first spatial information set;

[0131] The configuration of the second spatial information set is that the network device configures a second number of PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the second number is associated with the number of actually transmitted spatial information contained in the second spatial information set; or, the configuration of the second spatial information set is that the network device configures a third number of PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the third number is respectively associated with the number of actually transmitted spatial information contained in the second spatial information set and the number of actually transmitted spatial information contained in the third spatial information set.

[0132] In an embodiment of the present application, for the configuration of the first spatial information set, the first number of PDCCH monitoring opportunities corresponding to a paging occasion PO can be determined based on the number of actually transmitted spatial information contained in the first spatial information set, and / or, based on the number of PDCCH monitoring opportunities for each spatial information configured in the paging occasion.

[0133] In one implementation, with respect to the configuration of the first spatial information set, when a terminal device communicating with a network device through the first device monitors a paging message, a first number Y' of PDCCH monitoring opportunities corresponding to a paging occasion PO is associated with the number Y of actually transmitted spatial information included in the first spatial information set and the number X of PDCCH monitoring opportunities for each spatial information in the paging occasion PO. Exemplarily, the first number Y' may be Y×X, where Y is the number of actually transmitted spatial information included in the first spatial information set, and X is the number of PDCCH monitoring opportunities for each spatial information in the paging occasion PO.

[0134] In the embodiment of the present application, the configuration of the second spatial information set can be based on the amount of actually transmitted spatial information contained in the second spatial information set, or can be based on the amount of actually transmitted spatial information contained in the second spatial information set and the amount of actually transmitted spatial information contained in the third spatial information set.

[0135] Here, if the configuration of the second spatial information set is configured based on the number of actually transmitted spatial information contained in the second spatial information set, for the configuration of the second spatial information set, the second number of PDCCH monitoring opportunities corresponding to a paging occasion PO can be determined based on the number of actually transmitted spatial information contained in the second spatial information set, and / or, based on the number of PDCCH monitoring opportunities for each spatial information configured in the paging occasion.

[0136] In one implementation, with respect to the configuration of the second spatial information set, when a terminal device communicating with a network device through a first device monitors a paging message, a second number P' of PDCCH monitoring opportunities corresponding to a paging opportunity PO is associated with the number P of actually transmitted spatial information included in the second spatial information set and the number X of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO. Exemplarily, the second number P' may be P×X, where P is the number of actually transmitted spatial information included in the second spatial information set, and X is the number of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO.

[0137] Here, if the configuration of the second spatial information set is based on the number of actually transmitted spatial information contained in the second spatial information set and the number of actually transmitted spatial information contained in the third spatial information set, for the configuration of the second spatial information set, the second number of PDCCH listening opportunities corresponding to a paging occasion PO can be determined based on the number of actually transmitted spatial information contained in the second spatial information set and the number of actually transmitted spatial information contained in the third spatial information set, and / or, based on the number of PDCCH listening opportunities for each spatial information configured in the paging occasion.

[0138] In one implementation, for the configuration of the second spatial information set, the third number M of PDCCH monitoring opportunities corresponding to one paging opportunity PO is associated with the number P of actually transmitted spatial information included in the second spatial information set, the number S of actually transmitted spatial information included in the second spatial information set, and the number X of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO. Exemplarily, the third number M may be (S+P)×X, where P is the number of actually transmitted spatial information included in the second spatial information set, S is the number of actually transmitted spatial information included in the third spatial information set, and X is the number of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO.

[0139] In some embodiments, step 520 in which the terminal device determines paging resources based on the paging configuration information can also be implemented by the following steps: when the link quality between the terminal device and the network device meets a preset quality condition, the terminal device determines the paging resources based on the paging configuration information.

[0140] In an embodiment of the present application, the link quality may indicate the link quality of the link between the terminal device and the network device, and the link quality may be represented by at least one of reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal-to-noise ratio (SNR), signal-to-interference plus noise ratio (SINR), and channel state information (CSI).

[0141] In an embodiment of the present application, the preset quality condition may be that the link quality between the terminal device and the network device is less than or equal to a quality threshold; or the preset quality condition may be that the link quality of communication through the first device is greater than or equal to a quality threshold. The quality threshold may be configured by the network device, agreed upon in a protocol, or predefined. Here, link quality may also be referred to as channel quality or channel transmission quality.

[0142] In other embodiments of the present application, when the link quality between the terminal device and the network device is less than or equal to a quality threshold, it indicates that the channel transmission quality between the terminal device and the network device is poor; or when the link quality between the terminal device and the network device communicating through the first device is greater than or equal to the quality threshold, it indicates that the channel transmission quality between the terminal device and the network device communicating through the first device is good. In this case, it can be considered that the terminal device needs to communicate with the network device through forwarding by the first device. Further, based on the paging configuration information, the terminal device determines the paging resource as the paging resource corresponding to the spatial information set indicated by the paging configuration information. In this case, the terminal device uses the paging resource corresponding to the indicated spatial information to monitor the PDCCH scrambled by the P-RNTI at the PDCCH monitoring opportunity corresponding to the indicated spatial information set. In this way, based on the link quality between the terminal device and the network device, if the link quality is poor when the terminal device and the network device communicate directly, or if the link quality is good when the network device and the terminal device communicate through the first device, the first device reflects or refracts the signal transmitted between the network device and the terminal device, thereby ensuring both communication transmission quality and paging accuracy.

[0143] In an embodiment of the present application, when the terminal device determines that the link quality between it and the network device is greater than the quality threshold, it indicates that the channel transmission quality between the terminal device and the network device is good. At this time, it can be considered that the terminal device and the network device communicate directly without forwarding through the first device. Furthermore, even if the paging configuration information indicates the first spatial information set or the second spatial information set, the terminal device can still determine the paging resource as the third paging resource corresponding to the third spatial information set broadcast by the network device. At this time, the terminal device uses the PDCCH listening opportunity corresponding to the third paging resource to listen to the P-RNTI-scrambled PDCCH. In this way, according to the link quality between the terminal device and the network device, when the link quality is good when the terminal device and the network device communicate directly, the terminal device communicates directly with the network device, thereby ensuring the communication transmission quality and the accuracy of paging.

[0144] In some embodiments, the link quality between the terminal device and the network device determined by the terminal device may be the link quality obtained by the terminal device based on downlink reference signal measurements, or the link quality determined by the network device based on uplink reference signal measurements.

[0145] In some embodiments, the paging configuration information includes first indication information, the first indication information is used to indicate the first spatial information set or the second spatial information set, and the paging resource is the first paging resource or the second paging resource. In step 520, the terminal device determines the paging resource based on the paging configuration information, including: the terminal device determines the paging resource based on the first indication information used to indicate the first spatial information set or the second spatial information set.

[0146] Here, the paging resource may be determined by the terminal device based only on the first indication information.

[0147] In an embodiment of the present application, the first indication information is used to indicate a first spatial information set or a second spatial information set, representing that the terminal device communicates with the network device through the first device, that is, the spatial information set for communication between the terminal device and the first device is included in the first spatial information set or the second spatial information set. The terminal device monitors the PDCCH scrambled by the P-RNTI according to the PDCCH monitoring opportunity corresponding to the first spatial information set or the second spatial information set indicated by the first indication information, wherein the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the spatial information set indicated by the first indication information. In this way, after the introduction of the smart surface device, the terminal device can determine that the network device and the terminal device establish a communication link through the smart surface device based only on the first indication information in the paging configuration information. Furthermore, the terminal device uses the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the communication transmission quality while ensuring the accuracy of the paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0148] In some embodiments, when the first indication information indicates the first spatial information set, the paging resource is a first paging resource corresponding to the first spatial information set.

[0149] In an embodiment of the present application, when a terminal device communicates with a network device through a first device, if first indication information in paging configuration information sent by the network device indicates a first spatial information set, the terminal device may determine that the spatial information set forwarded by the first device is included in the first spatial information set, and determine that the paging resource is the first paging resource corresponding to the first spatial information set. In this case, the terminal device monitors the P-RNTI-scrambled PDCCH according to the PDCCH monitoring opportunity corresponding to the first spatial information set indicated by the first indication information. In this way, after the introduction of the smart surface device, when the first indication information indicates the first spatial information set, because the first spatial information set is part or all of the union of the second spatial information set forwarded by the smart surface device to the terminal device and the third spatial information set broadcast by the network device, and the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the first spatial information set indicated by the first indication information, the terminal device increases the number of blind detections so that it can monitor the paging message at the appropriate time, thereby improving communication transmission quality while ensuring paging accuracy, reducing the probability of paging false alarms, and reducing energy consumption of the terminal device.

[0150] It should be noted that, since the terminal device communicates with the network device through the first device, the terminal device only needs to monitor the P-RNTI-scrambled PDCCH repeatedly sent based on the spatial information in the second spatial information set contained in the first spatial information set; but since the first spatial information set also includes the third spatial information set, the terminal device also needs to monitor the P-RNTI-scrambled PDCCH repeatedly sent based on the spatial information in the third spatial information set; therefore, the terminal device increases the number of blind detections during the monitoring process.

[0151] For example, as shown in FIG6 , FIG6 is a schematic diagram illustrating how a paging occasion (PO) corresponds to a first spatial information set. Exemplarily, the first spatial information set is the union of a second spatial information set and a third spatial information set. The second spatial information set includes spatial information 0, spatial information 1, spatial information 2, and spatial information 3, and the third spatial information set includes spatial information 4, spatial information 5, spatial information 6, and spatial information 7. Spatial information 0, spatial information 1, spatial information 2, and spatial information 3 are different from spatial information 4, spatial information 5, spatial information 6, and spatial information 7. Therefore, the first spatial information set includes spatial information 0, spatial information 1, spatial information 2, spatial information 3, spatial information 4, spatial information 5, spatial information 6, and spatial information 7. Each spatial information corresponds to a PDCCH monitoring opportunity (PMO), i.e., spatial information 0 corresponds to PMO 0, spatial information 1 corresponds to PMO 1, spatial information 2 corresponds to PMO 2, spatial information 3 corresponds to PMO 3, spatial information 4 corresponds to PMO 4, spatial information 5 corresponds to PMO 5, spatial information 6 corresponds to PMO 6, and spatial information 7 corresponds to PMO 7. As shown in Figure 6, the paging resource corresponding to the PO monitored by the terminal device can be the first paging resource corresponding to the first spatial information set, that is, the terminal device blindly detects a paging opportunity PO corresponding to each spatial information in the first spatial information set and repeatedly sends the P-RNTI-encrypted PDCCH, thereby monitoring the paging.

[0152] In some embodiments, when the first indication information indicates the second spatial information set, the paging resource is a second paging resource corresponding to the second spatial information set.

[0153] In an embodiment of the present application, when a terminal device communicates with a network device through a first device, if the first indication information in the paging configuration information sent by the network device indicates a second spatial information set, the terminal device can determine that the spatial information set forwarded by the first device is the second spatial information set, and determine that the paging resource is the second paging resource corresponding to the second spatial information set. At this time, the terminal device monitors the P-RNTI-scrambled PDCCH according to the PDCCH monitoring opportunity corresponding to the second spatial information set indicated by the first indication information, wherein the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the second spatial information set indicated by the first indication information. In this way, after the introduction of the smart surface device, when the first indication information indicates the second spatial information set, since the second spatial information set is the second spatial information set forwarded by the smart surface device to the terminal device, and the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the second spatial information set indicated by the first indication information, compared with the first indication information indicating the first spatial information set, the terminal device can reduce unnecessary blind detections received by the terminal device. At the same time, the terminal device can also enable itself to monitor the paging message at the appropriate time, improve the communication transmission quality, do not increase the number of blind detections, while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0154] It should be noted that since the terminal device communicates with the network device through the first device, the terminal device only needs to detect the P-RNTI-encrypted PDCCH repeatedly sent by the spatial information in the second spatial information set corresponding to the first device to determine the paging message, and does not need to additionally detect the PDCCH monitoring timing corresponding to other spatial information; therefore, the terminal device does not need to increase the number of blind detections of the terminal device during the monitoring process, thereby reducing the terminal device from receiving unnecessary paging.

[0155] Exemplarily, referring to FIG7 , FIG7 is a schematic diagram of a paging opportunity PO corresponding to a second spatial information set, wherein, exemplarily, the second spatial information set includes spatial information 4, spatial information 5, spatial information 6, and spatial information 7, each of which corresponds to a PDCCH monitoring opportunity (PMO), i.e., spatial information 4 corresponds to PMO4, spatial information 5 corresponds to PMO5, spatial information 6 corresponds to PMO6, and spatial information 7 corresponds to PMO7. Referring to FIG7 , the paging resource corresponding to the PO detected by the terminal device may be the second paging resource corresponding to the second spatial information set, i.e., the terminal device blindly detects a paging opportunity PO corresponding to the PDCCH scrambled by repeatedly transmitting the P-RNTI based on each spatial information in the second spatial information set.

[0156] In some embodiments, the paging configuration information includes first indication information, and the first indication information is also used to indicate a third spatial information set; when the first indication information indicates the third spatial information set, the paging resource is the third paging resource; or, when the paging configuration information does not include the first indication information, the paging resource is the third paging resource. In step 520, the terminal device determines the paging resource based on the paging configuration information, including: the terminal device determines the paging resource based on the first indication information used to indicate the third spatial information set, or the terminal device determines the paging resource based on the paging configuration information that does not include the first indication information.

[0157] Here, the paging resource can be determined by the terminal device only based on the first indication information, and the first indication information is an optional configuration.

[0158] In an embodiment of the present application, the first indication information is used to indicate the third spatial information set, indicating that the terminal device can communicate directly with the network device without forwarding by the first device. The terminal device can determine that the spatial information set for communicating with the network device is included in the third spatial information set, and determine that the paging resource is the third paging resource corresponding to the third spatial information set. At this time, the terminal device blindly detects a paging opportunity PO corresponding to the spatial information in the third spatial information set and repeatedly sends the P-RNTI-encrypted PDCCH. In this way, after the introduction of the smart surface device, when the first indication information indicates the third spatial information set, the terminal device can determine that the network device and the terminal device directly establish a communication link. Furthermore, the terminal device uses the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the quality of communication transmission while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0159] It should be noted that when the first indication information is not configured in the paging configuration information, or the first indication information in the paging configuration information is absent, the terminal device can determine that the spatial information set for communicating with the network device is the third spatial information set, wherein the third spatial information set can be the spatial information included in the parameter ssb-PositionsInBurst in SIB1.

[0160] Exemplarily, referring to FIG8 , FIG8 is a schematic diagram of a paging opportunity PO corresponding to a third spatial information set, wherein, exemplarily, the third spatial information set includes spatial information 0, spatial information 1, spatial information 2, and spatial information 3, each of which corresponds to a PDCCH monitoring opportunity (PMO), i.e., spatial information 0 corresponds to PMO0, spatial information 1 corresponds to PMO1, spatial information 2 corresponds to PMO2, and spatial information 3 corresponds to PMO3. Referring to FIG8 , the paging resource corresponding to the PO detected by the terminal device may be the third paging resource corresponding to the third spatial information set, i.e., the terminal device blindly detects a paging opportunity PO corresponding to the PDCCH scrambled by repeatedly transmitting the P-RNTI based on each spatial information in the third spatial information set.

[0161] In some embodiments, if the paging configuration information only includes the first indication information, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0162] In an embodiment of the present application, an RRC release message or a specific signaling of a terminal device is a specific message configured by a network device for the terminal device. The RRC release message is used to instruct the terminal device to transition from an RRC connected state to an RRC idle state or an RRC inactive state. The specific signaling of the terminal device may be a high-level signaling dedicated to the terminal device. The RRC release message or the specific signaling of the terminal device may be sent by the network device to the terminal device when the terminal device enters a connected state, thereby reducing the power consumption of the terminal device. In an embodiment of the present application, the terminal device monitors the paging PDCCH based on the paging configuration information carried by the RRC release message or the specific signaling of the terminal device.

[0163] Exemplarily, the paging configuration information is included in higher-layer signaling dedicated to the terminal device UE, such as an RRC release message or PDCCH-configcommon. For different terminal devices, the corresponding spatial information set may be different. Optionally, the paging configuration information may be carried in the dedicated signaling of the terminal device.

[0164] In some embodiments, the paging configuration information further includes second indication information, the second indication information being used to indicate whether to apply the spatial information set indicated by the first indication information. Step 520, the terminal device determining the paging resource based on the paging configuration information, includes: the terminal device determining the paging resource based on the first indication information and the second indication information.

[0165] In an embodiment of the present application, the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information. The data type of the second indication information can be an enumeration type or a Boolean type, and this embodiment of the present application does not impose any restrictions on this.

[0166] In the embodiment of the present application, the first indication information is used to indicate the first spatial information set and the second spatial information set, and the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information. The terminal device determines the paging resource based on the first indication information and the second indication information, which may include:

[0167] The terminal device determines the paging resource based on the first indication information used to indicate the first spatial information set and the spatial information set indicated by the first indication information used to indicate application; or,

[0168] The terminal device determines the paging resource based on the first indication information used to indicate the first spatial information set and the first indication information used to indicate that the spatial information set indicated by the first indication information should not be applied; or,

[0169] The terminal device determines the paging resource based on the first indication information used to indicate the second spatial information set and the spatial information set indicated by the first indication information used to indicate the application; or,

[0170] The terminal device determines the paging resource based on the first indication information used to indicate the second spatial information set and the first indication information used to indicate that the spatial information set indicated by the first indication information should not be applied.

[0171] In this way, due to the mobility of the terminal device, the communication performance of the terminal device communicating with the network device through the first device in the area covered by the first device is better, while in other areas, the communication performance of the terminal device directly connected to the network device is better. Therefore, the embodiment of the present application determines the paging resource through the second indication information, so that the terminal device can select the paging resource corresponding to the appropriate spatial information set according to the distance between the terminal device and the network device to monitor the paging message, and thus can monitor the paging message at the appropriate time.

[0172] In some embodiments, the paging configuration information further includes second indication information. When the number of bits corresponding to the second indication information is the first number, if the second indication information is the first value, the paging resource is the first paging resource or the second paging resource; if the second indication information is the second value, the paging resource is the third paging resource; or,

[0173] When the number of bits corresponding to the second indication information is the second number, if the second indication information is the third value, the paging resource is the first paging resource; if the second indication information is the fourth value, the paging resource is the second paging resource; if the second indication information is the fifth value, the paging resource is the third paging resource;

[0174] The first quantity is different from the second quantity.

[0175] In an embodiment of the present application, the number of bits corresponding to the second indication information can be a first number such as 1, and the number of bits corresponding to the second indication information can also be a second number such as 2. Of course, the number of bits corresponding to the second indication information can also be other numbers other than the first number and the second number, such as 3, 4, 5, etc., and the embodiment of the present application does not impose any restrictions on this.

[0176] In an embodiment of the present application, the second indication information may indicate whether to apply the spatial information set indicated by the first indication information. The second indication information may also indicate the first spatial information set, the second spatial information set, or the third spatial information set. The second indication information may be represented by different values. Here, the second indication information may be the first value, the second value, the third value, the fourth value, or the fifth value.

[0177] In this embodiment of the present application, the first value may indicate the first spatial information set or the second spatial information set, and may also indicate that the spatial information set indicated by the first indication information is applied. The second value may indicate the third spatial information set, and may also indicate that the spatial information set indicated by the first indication information is not applied.

[0178] In an embodiment of the present application, the third value may indicate the first spatial information set, the fourth value may indicate the second spatial information set, and the fifth value may indicate the third spatial information set; of course, the third value and the fourth value may also indicate the application of the spatial information set indicated by the first indication information, and the fifth value may also indicate that the spatial information set indicated by the first indication information is not applied.

[0179] Exemplarily, when the number of bits corresponding to the second indication information is the first number, the first value may be 0 and the second value may be 1; or, the first value may be 1 and the second value may be 0.

[0180] Exemplarily, when the number of bits corresponding to the second indication information is the second number, the third value can be 00, the fourth value can be 01, and the fifth value can be 10; or, the third value can be 00, the fourth value can be 10, and the fifth value can be 11, or, the third value can be 00, the fourth value can be 01, the fifth value can be 10, and so on. It should be noted that when the number of bits corresponding to the second indication information is the second number, there can be multiple combinations between the third value, the fourth value and the fifth value, and this application does not enumerate them all.

[0181] Exemplarily, when the number of bits corresponding to the second indication information is another number such as 3, the third value can be 000, the fourth value can be 001, and the fifth value can be 100; or, the third value can be 000, the fourth value can be 010, and the fifth value can be 101, or, the third value can be 010, the fourth value can be 010, the fifth value can be 100, and so on. It should be noted that when the number of bits corresponding to the second indication information is the third number, there can be multiple combinations between the third value, the fourth value and the fifth value, and this application does not enumerate them all.

[0182] In an embodiment of the present application, when the number of bits corresponding to the second indication information is the first number, if the second indication information is the first value, the first value indicates the first spatial information set or the second spatial information set, or the first value indicates the spatial information set indicated by the first indication information, the paging resource is the first paging resource corresponding to the first spatial information set or the second paging resource corresponding to the second spatial information set; if the second indication information is the second value, the second value indicates the third spatial information set, and the paging resource is the third paging resource corresponding to the third spatial information set. In this way, due to the mobility of the terminal device, the communication performance of the terminal device communicating with the network device through the first device in the area covered by the first device is better, while in other areas, the communication performance of the terminal device directly connected to the network device is better. Therefore, the embodiment of the present application determines the paging resource by combining the first indication information and the second indication information, so that the terminal device can select the paging resource corresponding to the appropriate spatial information set according to the distance between the terminal device and the network device to monitor the paging message, and then can monitor the paging message at the appropriate time.

[0183] In an embodiment of the present application, when the number of bits corresponding to the second indication information is the second number, if the second indication information is a third value, the third value indicates the first spatial information set, and the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is a fourth value, the fourth value indicates the second spatial information set, and the paging resource is the second paging resource corresponding to the second spatial information set; if the second indication information is a fifth value, the fifth value indicates the third spatial information set, and the paging resource is the third paging resource corresponding to the second spatial information set. In this way, due to the mobility of the terminal device, the communication performance of the terminal device communicating with the network device through the first device in the area covered by the first device is better, while in other areas, the communication performance of the terminal device directly connected to the network device is better. Therefore, in an embodiment of the present application, the paging resource is determined by combining the first indication information and the second indication information, so that the terminal device can select the paging resource corresponding to the appropriate spatial information set according to the distance between the terminal device and the network device to monitor the paging message, and then can monitor the paging message at the appropriate time, thereby improving the communication transmission quality while ensuring the accuracy of the paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0184] In some embodiments, when the second indication information indicates to apply the spatial information set indicated by the first indication information, the second indication information is the first value or the third value;

[0185] When the second indication information indicates that the spatial information set indicated by the first indication information is not to be applied, the second indication information is the second value, the fourth value or the fifth value.

[0186] In an embodiment of the present application, the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information. Here, when the second indication information indicates to apply the spatial information set indicated by the first indication information, the second indication information is the first value or the third value; that is, the first value and the third value are used to indicate to apply the spatial information set indicated by the first indication information. When the second indication information indicates not to apply the spatial information set indicated by the first indication information, the second indication information is the second value, the fourth value, or the fifth value; that is, the second value, the fourth value, and the fifth value are used to indicate not to apply the spatial information set indicated by the first indication information.

[0187] In an embodiment of the present application, when the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information, and the second indication information is the first value or the third value (the first value and the third value indicate the application of the spatial information set indicated by the first indication information), the terminal device determines, based on the first indication information and the second indication information, that the first paging resource corresponding to the first spatial information set is the paging resource, or determines that the paging resource corresponding to the second spatial information is the paging resource.

[0188] In an embodiment of the present application, when the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is used to indicate whether the spatial information set indicated by the first indication information is applied, and the second indication information is the second value, the fourth value, or the fifth value (the second value, the fourth value, and the fifth value indicate that the spatial information set indicated by the first indication information is not applied), the terminal device determines, based on the first indication information and the second indication information, that the third paging resource corresponding to the third spatial information set is the paging resource, thereby monitoring the paging message based on the third paging resource.

[0189] In some embodiments, when the first indication information indicates the first spatial information set, if the second indication information is the first value or the third value, the paging resource is the first paging resource; or,

[0190] In the case where the first indication information indicates the second spatial information set, if the second indication information is the first value or the fourth value, the paging resource is the second paging resource; if the second indication information is the third value, the paging resource is the first paging resource;

[0191] In a case where the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is the second value or the fifth value, the paging resource is the third paging resource.

[0192] In an embodiment of the present application, the first value, the second value, the third value, the fourth value, and the fifth value all indicate a spatial information set. When the first value, the second value, the third value, the fourth value, and the fifth value all indicate a spatial information set, if the spatial information set indicated by the first indication information is completely inconsistent with the spatial information set indicated by the second indication information, the priority of the second indication information is higher than the priority of the first indication information, and the terminal device determines the paging resource based on the second indication information. If the spatial information set indicated by the first indication information is not completely consistent with the spatial information set indicated by the second indication information, the terminal device determines, based on the first indication information and the second indication information, that the paging resource corresponding to the spatial information set indicated by both the first indication information and the second indication information is the paging resource.

[0193] In a first possible implementation method, if the first indication information indicates the first spatial information set, the second indication information is a first value indicating the first spatial information set or the second spatial information set, or the second indication information is a third value indicating the first spatial information set, since the spatial information set indicated by the first indication information is not completely consistent with the spatial information set indicated by the second indication information, and both the first indication information and the second indication information indicate the first spatial information set, at this time, the terminal device determines, based on the first indication information and the second indication information, that the first paging resource corresponding to the first spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0194] In a second feasible manner, if the first indication information indicates the second spatial information set, the second indication information is a first value indicating the first spatial information set or the second spatial information set, or the second indication information is a fourth value indicating the second spatial information set, since the spatial information set indicated by the first indication information is not completely consistent with the spatial information set indicated by the second indication information, and both the first indication information and the second indication information indicate the second spatial information set, at this time, the terminal device determines, based on the first indication information and the second indication information, that the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0195] In a third possible implementation method, if the first indication information indicates the first spatial information set, or the first indication information indicates the second spatial set, the second indication information is the second value indicating the third spatial information set, or the second indication information is the fifth value indicating the third spatial information set, since the spatial information set indicated by the first indication information is completely inconsistent with the spatial information set indicated by the second indication information, and the priority of the second indication information is higher than the priority of the first indication information, at this time, the terminal device determines, based on the second indication information, that the third paging resource corresponding to the third spatial information set indicated by the second indication information is the paging resource.

[0196] In some embodiments, when the first value, the second value, the third value, the fourth value, and the fifth value all indicate spatial information sets, the determination of the paging resource is further associated with the configuration of the first spatial information set and the second spatial information set.

[0197] In one implementation, if the configuration of the first spatial information set is associated with the amount of actually transmitted spatial information contained in the first spatial information set, then, when the first indication information indicates the first spatial information set, if the second indication information is a first value having a first number of bits, wherein the first value indicates the first spatial information set or the second spatial information set, or the second indication information is a third value having a second number of bits, wherein the third value indicates the first spatial information set, then the terminal device determines that the first paging resource corresponding to the first spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0198] In another possible implementation, if the configuration of the second spatial information set is associated with the amount of actually transmitted spatial information contained in the second spatial information set, then, when the first indication information indicates the second spatial information set, if the second indication information is a first value having a first number of bits, wherein the first value indicates the first spatial information set or the second spatial information set, or the second indication information is a fourth value having a second number of bits, wherein the fourth value indicates the second spatial information set, then the terminal device determines that the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0199] In another possible implementation, if the configuration of the second spatial information set is associated with the number of spatial information actually transmitted contained in the second spatial information set and the number of spatial information actually transmitted contained in the third spatial information set, then, when the first indication information indicates the second spatial information set, there are two situations for determining the paging resource:

[0200] Case 1: If the second indication information is a first value having a first number of bits, wherein the first value indicates the first spatial information set or the second spatial information set, or the second indication information is a fourth value having a second number of bits, wherein the fourth value indicates the second spatial information set, then the terminal device determines that the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0201] Case 2: If the second indication information is a third value having a second number of bits, where the third value indicates the first spatial information set, since the second spatial information set includes the second spatial information set and the third spatial information set during the configuration process, and the priority of the second indication information is higher than the priority of the first indication information, then the terminal device determines that the first paging resource corresponding to the first spatial information set indicated by the second indication information is the paging resource.

[0202] For example, the number of bits corresponding to the second indication information is 1, the first value is 0, and the second value is 1; the number of bits corresponding to the second indication information is 2, the third value is 00, the fourth value is 01, and the fifth value is 10.

[0203] In the case where the second indication information is a first value, a second value, a third value, a fourth value and a fifth value, all of which indicate a spatial information set, if the first indication information indicates the first spatial information set, the second indication information is the first value (0) or the third value (00), since the first value (0) indicates the first spatial information set or the second spatial information set and the third value (00) indicates the first spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is the second value (1) or the fifth value (10), since the second value (1) and the fifth value (10) both indicate the third spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0204] In the case where the first value, the second value, the third value, the fourth value and the fifth value all indicate the spatial information set, if the first indication information indicates the second spatial information set, the second indication information is the first value (0) or the fourth value (01), since the first value (0) indicates the first spatial information set or the second spatial information set and the fourth value (01) indicates the second spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the second paging resource corresponding to the second spatial information set; if the second indication information is the third value (00), since the third value (00) indicates the first spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is the second value (1) or the fifth value (10), since the second value (1) and the fifth value (10) both indicate the third spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0205] In the case where the second indication information is a first value, a second value, a third value, a fourth value, and a fifth value indicating whether the spatial information set indicated by the first indication information is applied, if the first indication information indicates the first spatial information set, the second indication information is a first value (0) or a third value (00), since the first value (0) and the third value (00) both indicate the application of the spatial information set indicated by the first indication information, the terminal device determines, based on the second indication information, that the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is a second value (1), a fourth value (01), or a fifth value (10), since the second value (1), the fourth value (01), and the fifth value (10) both indicate that the spatial information set indicated by the first indication information is not applied, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0206] In the case where the second indication information is a first value, a second value, a third value, a fourth value and a fifth value indicating whether to apply the spatial information set indicated by the first indication information, if the first indication information indicates the second spatial information set, the second indication information is a first value (0) or a third value (00), since the first value (0) and the third value (00) both indicate the application of the spatial information set indicated by the first indication information, the terminal device determines, based on the second indication information, that the paging resource is the second paging resource corresponding to the second spatial information set; if the second indication information is a second value (1), a fourth value (01) or a fifth value (10), since the second value (1), the fourth value (01) and the fifth value (10) both indicate that the spatial information set indicated by the first indication information is not applied, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0207] In some embodiments, when the paging configuration information includes the second indication information, the first indication information is carried in the dedicated signaling of the serving cell where the terminal device is located, and the second indication information is carried in the radio resource control RRC release message or the dedicated signaling of the terminal device; or, the first indication information and the second indication information are carried in the RRC release message or the dedicated signaling of the terminal device;

[0208] In the case that the paging configuration information does not include the second indication information, the first indication information is carried in the RRC release message or the dedicated signaling of the terminal device.

[0209] In the embodiment of the present application, the paging configuration information includes first indication information and second indication information. The first indication information and the second indication information can be carried in the same signaling or different signaling.

[0210] Here, the first indication information and the second indication information are carried in different signalings, which can be understood as follows: the first indication information can be carried in the dedicated signaling of the service cell where the terminal device is located, and the second indication information can be carried in the RRC release message or the dedicated signaling of the terminal device. It should be noted that since the priority of the second indication information is higher than the priority of the first indication information, the second indication information can be carried in the RRC release message or the dedicated signaling of the terminal device, and the first indication information can be carried in the dedicated signaling of the service cell where the terminal device is located.

[0211] Exemplarily, the first indication information is carried in a system message such as a SIB1 message or PDCCH-configcommon, and the second indication information can be carried in an RRC release message or a dedicated signaling of the terminal device, thereby ensuring the accuracy of the paging configuration information received by the terminal device.

[0212] Here, the first indication information and the second indication information are carried in the same signaling, which can be understood as the first indication information and the second indication information are both carried in the RRC release message or the dedicated signaling of the terminal device. Exemplarily, the first indication information and the second indication information can be carried in the RRC release message or the dedicated signaling of the terminal device, so as to ensure the accuracy of the paging configuration information received by the terminal device.

[0213] In some embodiments, the paging configuration information further includes third indication information, and the third indication information is used to configure the first timer. Step 520, the terminal device determines the paging resource based on the paging configuration information, including: the terminal device determines the paging resource based on the first indication information and the first timer.

[0214] In an embodiment of the present application, the first timer is used to determine different time ranges, wherein the different time ranges include a range during which the first timer is running or a start time range, a range during which the first timer is not running, or a timeout time range.

[0215] In an embodiment of the present application, a terminal device determines whether a paging resource is a first paging resource, a second paging resource, or a third paging resource based on first indication information indicating the first spatial information set or the second spatial information set, and whether the first timer is running within the corresponding time range. Thus, when the first indication information indicates a spatial information set, the paging resource is determined based on the spatial information sets corresponding to different time ranges, thereby monitoring paging messages on the paging resource.

[0216] In some embodiments, determining the paging resource based on the first indication information and the first timer can be implemented as follows:

[0217] When the first indication information indicates the first spatial information set or the second spatial information set, during the operation of the first timer, the paging resource is the first paging resource corresponding to the first spatial information set or the second paging resource corresponding to the second spatial information set; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0218] In an embodiment of the present application, if the first indication information indicates the first spatial information set or the second spatial information set, and the first timer is in operation or in the start time range, the terminal device determines that the paging resource is the first paging resource corresponding to the first spatial information set or the second paging resource corresponding to the second spatial information set, and monitors the paging message on the first paging resource or the second paging resource. In this way, when the first indication information indicates the spatial information set, the paging resource is determined by the spatial information set corresponding to different time ranges (i.e., the timer start time range or the time range in which the timer is not started or has timed out), thereby monitoring the paging message on the paging resource.

[0219] In some embodiments, determining the paging resource based on the first indication information and the first timer may be implemented as follows:

[0220] When the first indication information indicates the first spatial information set, the paging resource is the first paging resource during the running of the first timer; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0221] When the first indication information indicates the second spatial information set, the paging resource is the second paging resource during the running of the first timer; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0222] In an embodiment of the present application, if the first indication information indicates the first spatial information set, and the first timer is in operation or in the start time range, the terminal device determines that the paging resource is the first paging resource corresponding to the first spatial information set, and monitors the paging message on the first paging resource. If the first indication information indicates the first spatial information set, and the first timer is not running or has timed out, the terminal device determines that the paging resource is the third paging resource corresponding to the third spatial information set, and monitors the paging message on the third paging resource. In this way, when the first indication information indicates the first spatial information set, the paging resource is determined by the spatial information set corresponding to different time ranges (i.e., the timer start time range or the time range in which the timer is not started or has timed out), thereby monitoring the paging message on the paging resource.

[0223] In an embodiment of the present application, if the first indication information indicates the second spatial information set, and the first timer is in operation or in the start time range, the terminal device determines that the paging resource is the second paging resource corresponding to the second spatial information set, and monitors the paging message on the second paging resource. If the first indication information indicates the second spatial information set, and the first timer is not running or has timed out, the terminal device determines that the paging resource is the third paging resource corresponding to the third spatial information set, and monitors the paging message on the third paging resource. In this way, when the first indication information indicates the second spatial information set, the paging resource is determined by the spatial information set corresponding to different time ranges (i.e., the timer start time range or the time range in which the timer is not started or has timed out), thereby monitoring the paging message on the paging resource.

[0224] For example, referring to FIG9 , FIG9 is a schematic diagram of determining a spatial information set corresponding to a paging opportunity PO based on a timer. Taking the first indication information indicating the second spatial information set as an example, during the operation of the first timer, the spatial information set corresponding to the paging opportunity PO1 is the second spatial information set. At this time, the terminal device monitors the paging message on the second paging resource corresponding to the second spatial information set. When the first timer is not running or times out, the spatial information set corresponding to the paging opportunity PO2 is the third spatial information set. At this time, the terminal device monitors the paging message on the third paging resource corresponding to the third spatial information set. In this way, the terminal device can receive the paging message at the appropriate time based on the timer.

[0225] In some embodiments, the configuration of the first timer is associated with information related to the mobility of the terminal device, where the information related to the mobility of the terminal device includes one or more of the following:

[0226] The location of the terminal equipment;

[0227] The speed of the terminal device;

[0228] Movement patterns of terminal equipment;

[0229] Movement direction of the terminal device;

[0230] The timestamp corresponding to the terminal device's location.

[0231] In an embodiment of the present application, the position of the terminal device indicates whether the terminal device is located in the area provided by the first device during paging. If the terminal device is located in the service area provided by the first device, the terminal device communicates with the network device through the first device. If the terminal device is not in the service area provided by the first device, the terminal device communicates with the network device directly. That is, the position of the terminal device determines whether the terminal device communicates with the network device through the first device or directly with the network device, thereby selecting a communication method based on the position of the terminal device, and then dynamically allocating different spatial information sets to different time ranges of the first timer based on the selected communication method, so that the terminal device can monitor the paging message at the appropriate time. For example, when the terminal device is at position 1, it can communicate directly with the network device, that is, without the need for the first device to forward the signal, and the paging resource can be the paging resource corresponding to the third spatial information set; when the terminal device moves to position 2, due to the obstruction between the terminal device and the network device, it communicates with the network device through the first device, and the paging resource can be the paging resource corresponding to the first spatial information set or the second spatial information set.

[0232] In an embodiment of the present application, the speed of the terminal device determines the movement time of the terminal device in the area provided by the first device and / or network device in the paging. The movement time used by the terminal device can determine the running time of the first timer, thereby dynamically allocating different spatial information sets to different time ranges of the first timer, so that the terminal device can monitor the paging message at the appropriate time.

[0233] In an embodiment of the present application, the movement pattern of the terminal device means that the movement trajectory pattern of the terminal device in the area provided by the first device or the network device is taken into consideration during paging. Based on the movement trajectory pattern, the time domain in which the terminal device can communicate directly with the network device can be determined, as well as the time domain in which the terminal device needs to communicate with the network device through the first device can be determined, thereby dynamically allocating different spatial information sets to different time ranges of the first timer, so that the terminal device can monitor the paging message at the appropriate time.

[0234] In an embodiment of the present application, the movement direction of the terminal device indicates that the movement direction of the terminal device in the area provided by the first device or the network device is considered in paging. Based on the movement direction, the time domain in which the terminal device can communicate directly with the network device can be determined, and the time domain in which the terminal device needs to communicate with the network device through the first device can be determined, thereby dynamically allocating different spatial information sets to different time ranges of the first timer, so that the terminal device can monitor the paging message at the appropriate time.

[0235] It should be noted that since the setting of the first timer is closely related to the mobility of the terminal device, it is necessary to know the movement trajectory of the terminal device. Based on the movement trajectory, the time domain in which the terminal device can communicate directly with the network device and the time domain in which the terminal device communicates with the network device through the first device are determined, so as to dynamically allocate different spatial information sets to different time ranges of the first timer.

[0236] It is understandable that due to mobility, the terminal device will receive a paging message in the paging resources corresponding to the third spatial information set in a certain area, and receive a paging message in the paging resources corresponding to the first spatial information set or the second spatial information set in another area. For example, the terminal device is located in the first area, and the terminal device receives a paging message in the paging resources corresponding to the third SSB set; the terminal device is located in the second area, and the terminal device receives a paging message in the paging resources corresponding to the first SSB set or the second SSB set. The time taken by the terminal device to move from the first area to the second area can be the time range of the first timer; wherein, the position of the terminal device is calculated by the terminal device through a downlink positioning method and reported to the network device, or is calculated by the network device through an uplink positioning method.

[0237] It can be understood that when configuring the spatial information set according to the first timer, since the terminal device corresponds to different spatial information sets in different time ranges, it is necessary to consider the impact of the terminal device's mobility on the terminal device's monitoring of paging messages, so that the terminal device can receive the paging message at the appropriate time.

[0238] In some embodiments, if the paging configuration information includes the first indication information and the third indication information, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0239] In an embodiment of the present application, the RRC release message or the specific signaling of the terminal device is a specific message configured by the network device for the terminal device, and the terminal device monitors the paging PDCCH based on the first indication information and the third indication information in the paging configuration information carried by the RRC release message or the specific signaling of the terminal device.

[0240] In some embodiments, the paging configuration information further includes fourth indication information, and the fourth indication information is used to configure the spatial information set pattern.

[0241] Here, the spatial information set pattern is associated with one or more of the following:

[0242] Radio frame PF of the terminal device;

[0243] PO in the PF of the terminal device;

[0244] Time domain subframe configuration of the terminal device.

[0245] Here, different PFs in a discontinuous reception DRX cycle in the spatial information set pattern correspond to different spatial information sets; different POs in a PF in a DRX cycle in the spatial information set pattern correspond to different spatial information sets; and different subframes in a system frame included in the spatial information set pattern correspond to different spatial information sets.

[0246] In an embodiment of the present application, a terminal device is provided with a plurality of radio frames PF for receiving paging messages in a discontinuous period DRX cycle, and each radio frame PF corresponds to a plurality of paging occasions PO.

[0247] In the embodiment of the present application, different PFs in a discontinuous reception DRX cycle in the spatial information set pattern may correspond to the same or different spatial information sets. That is, the spatial information sets corresponding to different PFs may be the same, or the spatial information sets corresponding to different PFs may be different, but the spatial information sets corresponding to different POs in the same PF are the same.

[0248] Exemplarily, the number of PFs monitored by the terminal device within a DRX cycle is 2, the spatial information set corresponding to the first PF is the second spatial information set, and the spatial information set corresponding to the second PF is the third spatial information set, that is, the spatial information sets corresponding to different PFs are different, and the spatial information sets corresponding to different POs in the same PF are the same.

[0249] In another example, the number of PFs monitored by the terminal device within a DRX cycle is 4, the spatial information set corresponding to the first PF is the first spatial information set, the spatial information set corresponding to the second PF is the second spatial information set, the spatial information set corresponding to the third PF is the third spatial information set, and the spatial information set corresponding to the fourth PF is the second spatial information set; that is, the spatial information sets corresponding to different PFs may be the same or different, and the spatial information sets corresponding to different POs in the same PF are the same.

[0250] In an embodiment of the present application, different POs within a PF within a DRX cycle in the spatial information set pattern may correspond to the same or different spatial information sets, that is, the spatial information sets corresponding to different POs may be the same, or the spatial information sets corresponding to different POs may be different.

[0251] Exemplarily, the number of POs of the terminal device within a PF is 2, that is, the terminal device monitors paging messages at two POs within a PF, the spatial information set corresponding to the first P0 is the second spatial information set, and the spatial information set corresponding to the second P0 is the third spatial information set, that is, different P0s correspond to different spatial information sets.

[0252] In another example, the number of POs of the terminal device within a PF is 4, the spatial information set corresponding to the first PO is the first spatial information set, the spatial information set corresponding to the second PO is the second spatial information set, the spatial information set corresponding to the third PO is the third spatial information set, and the spatial information set corresponding to the fourth PO is the second spatial information set; that is, the spatial information sets corresponding to different POs may be the same or different.

[0253] In an embodiment of the present application, different subframes in a system frame included in the spatial information set pattern may correspond to the same or different spatial information sets. It should be noted that a system frame includes multiple subframes, such as 10 subframes. The spatial information set corresponding to the first part of the subframes in the system frame is the second spatial information set, and the spatial information set corresponding to the second part of the subframes is the third spatial information set, wherein the first part of the subframes includes one or more subframes in the system frame, and the second part of the subframes includes other subframes in the system frame except the first part of the subframes; or, the spatial information set corresponding to the first part of the subframes in the system frame is the first spatial information set, the spatial information set corresponding to the second part of the subframes is the second spatial information set, and the spatial information set corresponding to the third part of the subframes is the third spatial information set, wherein the first part of the subframes, the second part of the subframes and the third part of the subframes are different, and the system frame includes the first part of the subframes, the second part of the subframes and the third part of the subframes. Here, since the beam set supported by the first device may be associated with the time domain subframe configuration, the beam sets supported by different one or more subframes may be different, and adjusting the spatial information set in a semi-static manner can reduce signaling overhead.

[0254] In some embodiments, the configuration of the spatial information set pattern is associated with information related to the mobility of the terminal device, wherein the information related to the mobility of the terminal device includes one or more of the following:

[0255] The location of the terminal equipment;

[0256] The speed of the terminal device;

[0257] Movement patterns of terminal equipment;

[0258] Movement direction of the terminal device;

[0259] The timestamp corresponding to the terminal device's location.

[0260] In an embodiment of the present application, the location of the terminal device indicates whether the terminal device is located in the area provided by the first device during paging. If the terminal device is located in the service area provided by the first device, the terminal device communicates with the network device through the first device. If the terminal device is not in the service area provided by the first device, the terminal device communicates directly with the network device. That is, the location of the terminal device determines whether the terminal device communicates with the network device through the first device or directly with the network device, thereby selecting a communication method based on the location of the terminal device, and then dynamically allocating different spatial information sets based on the spatial information set pattern according to the selected communication method, so that the terminal device can monitor the paging message at the appropriate time. For example, when the UE is in position 1, it can communicate directly with the network device, that is, without the need for the first device to forward the signal, and the paging resource can be the paging resource corresponding to the third spatial information set; when the UE moves to position 2, because there is an obstruction between it and the network device, it communicates with the network device through the first device, and the paging resource can be the paging resource corresponding to the first spatial information set or the second spatial information set.

[0261] In an embodiment of the present application, the speed of the terminal device determines the movement time of the terminal device in the area provided by the first device and / or the network device to be considered in paging. The movement time of the terminal device determines the configuration of the spatial information set pattern, and thus different spatial information sets are dynamically allocated based on the spatial information set pattern, so that the terminal device can monitor the paging message at the appropriate time.

[0262] In an embodiment of the present application, the movement pattern of the terminal device means that the movement trajectory pattern of the terminal device in the area provided by the first device or the network device is taken into consideration during paging. Based on the movement trajectory pattern, the time domain in which the terminal device can communicate directly with the network device can be determined, as well as the time domain in which the terminal device needs to communicate with the network device through the first device can be determined. Therefore, based on the spatial information set pattern, different spatial information sets are dynamically allocated, so that the terminal device can monitor the paging message at the appropriate time.

[0263] In an embodiment of the present application, the movement direction of the terminal device indicates that the movement direction of the terminal device in the area provided by the first device or the network device is considered in paging. Based on the movement direction, the time domain in which the terminal device can communicate directly with the network device can be determined, and the time domain in which the terminal device needs to communicate with the network device through the first device can be determined. Therefore, based on the spatial information set pattern, different spatial information sets are dynamically allocated, so that the terminal device can monitor the paging message at the appropriate time.

[0264] It should be noted that due to the high mobility of the terminal device, it is necessary to know the movement trajectory of the terminal device. Based on the movement trajectory, the time domain in which the terminal device can communicate directly with the network device and the time domain in which the terminal device communicates with the network device through the first device are determined. In this way, different spatial information sets are dynamically allocated based on the spatial information set pattern, so that the terminal device can monitor the paging message at the appropriate time.

[0265] It can be understood that when the spatial information set is configured according to the spatial information set pattern, due to mobility, the terminal device corresponds to different spatial information sets at different times. For example, the UE position is located in the first area, the SSB set pattern is the third SSB set, the UE position is located in the second area, and the SSB set pattern is the first SSB set or the second SSB set. The UE position is calculated by the UE through a downlink positioning method and reported to the network device, or is calculated by the network device through an uplink positioning method. Therefore, it is necessary to consider the impact of the mobility of the terminal device on the terminal device's monitoring of the paging message, so that the terminal device can receive the paging message at the appropriate time.

[0266] In some embodiments, if the paging configuration information includes the first indication information and the fourth indication information, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0267] In an embodiment of the present application, the RRC release message or the specific signaling of the terminal device is a specific message configured by the network device for the terminal device, and the terminal device monitors the paging PDCCH based on the first indication information and the fourth indication information in the paging configuration information carried by the RRC release message or the specific signaling of the terminal device.

[0268] In some embodiments, before the terminal device receives the paging configuration information sent by the network device in step 510, the terminal device reports first information to the network device, wherein the paging configuration information is determined based on the first information;

[0269] The first information includes one or more of the following:

[0270] Information related to the mobility of terminal devices;

[0271] The measurement result of the service cell where the terminal device is located is obtained based on the measurement configuration information sent by the network device.

[0272] In the embodiment of the present application, the information related to the mobility of the terminal device includes one or more of the following:

[0273] The location of the terminal equipment;

[0274] The speed of the terminal device;

[0275] Movement patterns of terminal equipment;

[0276] Movement direction of the terminal device;

[0277] The timestamp corresponding to the terminal device's location.

[0278] In an embodiment of the present application, the measurement result is a result obtained by the terminal device measuring the service cell where the terminal device is located based on the measurement configuration information sent by the network device. The measurement result may include one or more of the following measurement parameters: channel measurement result, reference signal received power, reference signal received quality, signal-to-noise ratio, signal-to-interference-and-noise ratio, and other parameters. The embodiment of the present application does not limit this.

[0279] In an embodiment of the present application, mobility-related information such as the location of the terminal device, the speed of the terminal device, the movement pattern of the terminal device, the movement direction of the terminal device, and the timestamp corresponding to the location of the terminal device can provide parameters for configuring paging configuration information for the network device. For example, the network device determines whether the terminal device is located in the area provided by the first device based on the location of the terminal device. If the terminal device is located in the service area provided by the first device, the paging configuration information configured by the network device for the terminal device indicates the second spatial information set, so that the terminal device monitors the paging message at an appropriate time according to the paging configuration information.

[0280] FIG10 shows a paging method provided by an embodiment of the present application, which is applied to a network device. The method may include:

[0281] Step 610: When the first device reflects or refracts a signal transmitted between the network device and the terminal device, the network device sends paging configuration information to the terminal device, wherein the paging configuration information is used to indicate the first spatial information set or the second spatial information set, so that the terminal device determines the paging resources based on the paging configuration information; the paging resources are the paging resources corresponding to the first spatial information set, the second spatial information set, or the third spatial information set; the first spatial information set is all or part of the union of the second spatial information set and the third spatial information set; the third spatial information set is the spatial information set broadcast by the network device; and the second spatial information set is the spatial information set of the first device.

[0282] In this embodiment of the present application, the spatial information in the spatial information set may be beam information corresponding to a paging resource. The spatial information set may be any one of an SSB set, a channel state reference signal (CSI-RS) resource set, a channel sounding reference signal (SRS) resource set, a transmission configuration indicator (TCI) state set, a unified TCI state set, a downlink spatial relation filter set, an uplink spatial relation filter set, and a quasi-co-site QCL relationship.

[0283] Here, paging includes the PDCCH scrambled by the P-RNTI and the PDSCH scheduled by the PDCCH. When the terminal device is in the RRC idle state or inactive state, the network device can page the terminal device via a paging message, or notify the terminal device of information such as message changes, earthquakes, tsunamis, and public warnings via a short message. In one implementation, the paging message can be transmitted in the PDSCH, and the short message can be 8 bits in the PDCCH.

[0284] In the embodiment of the present application, the paging configuration information is used to indicate information of the first spatial information set or the second spatial information set. Of course, the paging configuration information may also indicate the third spatial information set.

[0285] In the embodiment of the present application, the third spatial information set may be a spatial information set broadcast by the network device. Here, the spatial information set broadcast by the network device may be a spatial information set configured by the high-layer parameter ssb-PositionsInBurst in the system information block SIB1.

[0286] In the embodiment of the present application, the first device may be a smart surface device, such as a RIS device. It should be noted that the first device may implement signal forwarding between the terminal device and the network device.

[0287] Here, the spatial information set of the first device can be understood as a spatial information set supported by the first device or a spatial information set associated with the first device. The first device is used to forward signals sent by a network device to a terminal device, or to forward signals sent by a terminal device to a network device. Forwarding includes reflection or refraction, thereby changing the direction of signal transmission.

[0288] It is understood that the signal can be information carried on an uplink channel sent by a network device (forwarded by the first device) to a terminal device, that is, the signal can be an uplink reference signal; the signal can also be information carried on a downlink channel sent by a terminal device (forwarded by the first device) to a network device, that is, the signal can be a downlink reference signal. It should be noted that the spatial information set belongs to the downlink reference signal.

[0289] It is understandable that the network device may directly send the third spatial information set to the terminal device; of course, the network device may also forward the second spatial information set to the terminal device through the first device.

[0290] It should be noted that, for a terminal device that communicates directly with a network device, the spatial information set corresponding to a paging occasion PO may be the third spatial information set broadcast by the network device; for a terminal device that communicates with the network device through a first device, the spatial information set corresponding to a paging occasion PO may be the second spatial information set, or the first spatial information set, that is, all or part of the union of the second spatial information set and the third spatial information set.

[0291] In the embodiment of the present application, the first spatial information set is the entirety of the union of the second spatial information set and the third spatial information set, which may mean that the first spatial information set includes the spatial information in the second spatial information set and the spatial information in the third spatial information set.

[0292] In the embodiment of the present application, the first spatial information set is a part of the union of the second spatial information set and the third spatial information set, which may mean that the first spatial information set includes part of the spatial information in the second spatial information set, or the first spatial information set includes part of the spatial information in the third spatial information set, or the first spatial information set includes part of the spatial information in the second spatial information set and part of the spatial information in the third spatial information set. This application does not impose any specific restrictions on this.

[0293] It should be noted that the first spatial information set, the second spatial information set, and the third spatial information set are not completely identical. For example, the spatial information contained in the first spatial information set, the second spatial information set, and the third spatial information set is not completely identical. For example, the amount of spatial information contained in the first spatial information set, the second spatial information set, and the third spatial information set is not completely identical, and / or the signals corresponding to the spatial information contained in the first spatial information set, the second spatial information set, and the third spatial information set are not completely identical.

[0294] In the embodiment of the present application, the spatial information set corresponding to one paging occasion PO may be the first spatial information set, the second spatial information set, or the third spatial information set.

[0295] In the embodiment of the present application, the paging resource may be a paging resource corresponding to a spatial information set corresponding to a paging occasion PO, that is, the paging resource may be a paging resource corresponding to one of the first spatial information set, the second spatial information set, and the third spatial information set. It should be noted that the paging resource may be configured by the network device and may be included in the paging configuration information. Of course, the paging resource may also be configured by other signaling. This application does not impose specific limitations on this.

[0296] It is understood that in the embodiments of the present application, the network device and the terminal device can communicate directly or through the first device. When the network device and the terminal device communicate through the first device, the network device sends paging configuration information indicating the first spatial information set or the second spatial information set to the terminal device, and the terminal device determines the paging resource based on the paging configuration information. In this way, after determining the paging resource, the terminal device uses the paging resource to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information in the indicated spatial information set, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information in the indicated spatial information set. In this way, after introducing the smart surface device, the terminal device can determine that the network device and the terminal device establish a communication link through the smart surface device based on the paging configuration information indicating the first spatial information set or the second spatial information set sent by the network device, so that the terminal device can use the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the communication transmission quality while ensuring the accuracy of the paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0297] In some embodiments, the first spatial information set is the entirety of the union of the second spatial information set and the third spatial information set, which may include: the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the second spatial information set, and / or the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the third spatial information set.

[0298] In the embodiment of the present application, since the first spatial information set is the entirety of the union of the second and third spatial information sets, the first spatial information set can include both the second and third spatial information sets. Generally, the second and third spatial information sets are not empty. Therefore, if the first spatial information set includes the second spatial information set, the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the second spatial information set; and if the first spatial information set includes the third spatial information set, the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the third spatial information set.

[0299] In some embodiments, the first spatial information set is all or part of the union of the second spatial information set and the third spatial information set, which may include: the amount of spatial information in the first spatial information set is equal to or less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0300] It should be noted that the second spatial information set and the third spatial information set are not completely identical, that is, the spatial information in the second spatial information set is completely different from the spatial information in the third spatial information set, and there is some commonality between the spatial information in the second spatial information set and the spatial information in the third spatial information set. When the first spatial information set is all or part of the union of the second spatial information set, the relationship between the amount of spatial information in the first spatial information set and the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set includes:

[0301] In the case where the first spatial information set is the entire union of the second spatial information set, if the spatial information in the second spatial information set and the spatial information in the third spatial information set are completely different, then the amount of spatial information in the first spatial information set is equal to the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0302] In a case where the first spatial information set is the entirety of the union of the second spatial information set, if the spatial information in the second spatial information set and the spatial information in the third spatial information set are not completely identical, the amount of spatial information in the first spatial information set is less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0303] In the case where the first spatial information set is part of the union of the second spatial information set, regardless of whether the spatial information in the second spatial information set and the spatial information in the third spatial information set are completely different or not completely different, the amount of spatial information in the first spatial information set is less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0304] In some embodiments, different spatial information sets correspond to different paging resources, and the different spatial information sets include one or more of the following: a first spatial information set, a second spatial information set, and a third spatial information set. Different spatial information sets corresponding to different paging resources include: the first spatial information set corresponding to a first paging resource, the second spatial information set corresponding to a second paging resource, and the third spatial information set corresponding to a third paging resource.

[0305] In an embodiment of the present application, the first paging resource can be used by the terminal device to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information in the first spatial information set under the paging occasion PO, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information included in the first spatial information set. Exemplarily, if the number of spatial information included in the first spatial information set is Y, the P-RNTI-scrambled PDCCH is monitored at Y' PDCCH monitoring opportunities corresponding to Y spatial information; wherein Y and Y' may be the same, or Y and Y' may be different. It should be noted that, when each spatial information is configured to correspond to X PDCCH monitoring opportunities in the paging occasion PO, if X=1, then Y and Y' are the same; if X>1, then Y and Y' are different, and the relationship between Y and Y' is Y'=Y×X.

[0306] In an embodiment of the present application, the second paging resource can be used by the terminal device to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information included in the second spatial information set under the paging occasion PO, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information included in the second spatial information set. Exemplarily, if the number of spatial information included in the second spatial information set is P, the P-RNTI-scrambled PDCCH is monitored at P' PDCCH monitoring opportunities corresponding to P spatial information; wherein P and P' can be the same, or P and P' can be different. It should be noted that, when each spatial information is configured to correspond to X PDCCH monitoring opportunities in the paging occasion PO, if X=1, then P and P' are the same; if X>1, then P and P' are different, and the relationship between P and P' is P'=P×X.

[0307] In an embodiment of the present application, the third paging resource can be used by the terminal device to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information included in the third spatial information set under the paging occasion PO, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information included in the third spatial information set. Exemplarily, if the number of spatial information included in the third spatial information set is S, the P-RNTI-scrambled PDCCH is monitored at S' PDCCH monitoring opportunities corresponding to the S spatial information; wherein S and S' may be the same, and P and P' may be different. It should be noted that, when each spatial information is configured to correspond to X PDCCH monitoring opportunities in the paging occasion PO, if X=1, then S is the same as S'; if X>1, then S is different from S', and the relationship between S and S' is S'=S×X.

[0308] In some embodiments, the first paging resource, the second paging resource, and the third paging resource satisfy at least one of the following:

[0309] The first paging resource includes a second paging resource and a third paging resource;

[0310] The PDCCH monitoring opportunities corresponding to the second paging resource and the third paging resource do not overlap in the time domain;

[0311] The PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the time domain;

[0312] The PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the frequency domain;

[0313] The first paging resource, the second paging resource, and the third paging resource are scrambled and indicated using different paging radio network temporary identifiers P-RNTIs.

[0314] In the embodiment of the present application, since the first spatial information set may include the second spatial information set and the third spatial information set, the first paging resource corresponding to the first spatial information set may include the second paging resource corresponding to the second spatial information set and the third paging resource corresponding to the third spatial information set.

[0315] In the embodiment of the present application, by distinguishing time domain resources, the PDCCH monitoring opportunities corresponding to the second paging resource and the third paging resource do not overlap in the time domain.

[0316] In the embodiment of the present application, time domain resources are distinguished, that is, the PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the time domain.

[0317] In the embodiment of the present application, frequency domain resources are distinguished, that is, the PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the frequency domain.

[0318] In an embodiment of the present application, different P-RNTIs can be used to distinguish the first paging resource, the second paging resource, and the third paging resource, that is, the first paging resource, the second paging resource, and the third paging resource are respectively indicated using different P-RNTI scrambling, so that the terminal device monitors the PDCCH scrambled by the P-RNTI corresponding to the paging resource within the PO.

[0319] In some embodiments, the configuration of the first spatial information set and the second spatial information set may be achieved as follows:

[0320] The configuration of the first spatial information set is that the network device configures a first number of physical downlink control channel PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the first number is associated with the number of actually transmitted spatial information contained in the first spatial information set;

[0321] The configuration of the second spatial information set is that the network device configures a second number of PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the second number is associated with the number of actually transmitted spatial information contained in the second spatial information set; or, the configuration of the second spatial information set is that the network device configures a third number of PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the third number is respectively associated with the number of actually transmitted spatial information contained in the second spatial information set and the number of actually transmitted spatial information contained in the third spatial information set.

[0322] In an embodiment of the present application, for the configuration of the first spatial information set, the first number of PDCCH monitoring opportunities corresponding to a paging occasion PO can be determined based on the number of actually transmitted spatial information contained in the first spatial information set, and / or, based on the number of PDCCH monitoring opportunities for each spatial information configured in the paging occasion.

[0323] In one implementation, with respect to the configuration of the first spatial information set, when a terminal device communicates with a network device through the first device, the network device associates, for a paging opportunity PO corresponding to the terminal device, a first number Y' of PDCCH monitoring opportunities corresponding to the paging opportunity PO with the number Y of actually transmitted spatial information included in the first spatial information set and the number X of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO. Exemplarily, the first number Y' may be Y×X, where Y is the number of actually transmitted spatial information included in the first spatial information set, and X is the number of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO.

[0324] In an embodiment of the present application, for the configuration of the second spatial information set, the network device can be configured based on the amount of actually transmitted spatial information contained in the second spatial information set, or based on the amount of actually transmitted spatial information contained in the second spatial information set and the amount of actually transmitted spatial information contained in the third spatial information set.

[0325] Here, if the configuration of the second spatial information set is configured by the network device based on the number of actually transmitted spatial information contained in the second spatial information set, for the configuration of the second spatial information set, the network device configures a paging opportunity PO corresponding to the terminal device, and the second number of PDCCH monitoring opportunities corresponding to the paging opportunity PO can be determined based on the number of actually transmitted spatial information contained in the second spatial information set, and / or, based on the number of PDCCH monitoring opportunities for each spatial information configured in the paging opportunity.

[0326] In one implementation, with respect to the configuration of the second spatial information set, when a terminal device communicates with a network device through the first device, the network device associates, for a paging opportunity PO corresponding to the terminal device, a second number P' of PDCCH monitoring opportunities corresponding to the paging opportunity PO with the number P of actually transmitted spatial information included in the second spatial information set and the number X of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO. Exemplarily, the second number P' may be P×X, where P is the number of actually transmitted spatial information included in the second spatial information set, and X is the number of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO.

[0327] Here, if the configuration of the second spatial information set is configured by the network device based on the number of actually transmitted spatial information contained in the second spatial information set and the number of actually transmitted spatial information contained in the third spatial information set, for the configuration of the second spatial information set, the network device configures a paging opportunity PO corresponding to the terminal device, and the second number of PDCCH listening opportunities corresponding to the paging opportunity PO can be determined based on the number of actually transmitted spatial information contained in the second spatial information set and the number of actually transmitted spatial information contained in the third spatial information set, and / or, based on the number of PDCCH listening opportunities for each spatial information configured in the paging opportunity.

[0328] In one implementation, for the configuration of the second spatial information set, the network device associates, for a paging opportunity PO corresponding to the terminal device, a third number M of PDCCH monitoring opportunities corresponding to the paging opportunity PO with the number P of actually transmitted spatial information included in the second spatial information set, the number S of actually transmitted spatial information included in the second spatial information set, and the number X of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO. Exemplarily, the third number M may be (S+P)×X, where P is the number of actually transmitted spatial information included in the second spatial information set, S is the number of actually transmitted spatial information included in the third spatial information set, and X is the number of PDCCH monitoring opportunities for each spatial information in the paging opportunity PO.

[0329] In some embodiments, the terminal device determines the paging resources based on the paging configuration information, which can also be achieved through the following steps: when the link quality between the terminal device and the network device meets the preset quality condition, the terminal device determines the paging resources based on the paging configuration information.

[0330] In an embodiment of the present application, the link quality may indicate the link quality of the link between the terminal device and the network device, and the link quality may be represented by at least one of reference signal reception power, reference signal reception quality, signal-to-noise ratio, signal-to-interference-plus-noise ratio, and channel state information.

[0331] In an embodiment of the present application, the preset quality condition may be that the link quality between the terminal device and the network device is less than or equal to a quality threshold; or the preset quality condition may be that the link quality of communication through the first device is greater than or equal to a quality threshold. The quality threshold may be configured by the network device, agreed upon in a protocol, or predefined. Here, link quality may also be referred to as channel quality or channel transmission quality.

[0332] In other embodiments of the present application, when the link quality between the terminal device and the network device is less than or equal to a quality threshold, it indicates that the channel transmission quality between the terminal device and the network device is poor; or when the link quality between the terminal device and the network device communicating through the first device is greater than or equal to the quality threshold, it indicates that the channel transmission quality between the terminal device and the network device communicating through the first device is good. In this case, it can be considered that the terminal device needs to communicate with the network device through forwarding by the first device. Further, based on the paging configuration information, the terminal device determines the paging resource as the paging resource corresponding to the spatial information set indicated by the paging configuration information. In this case, the terminal device uses the paging resource corresponding to the indicated spatial information to monitor the PDCCH scrambled by the P-RNTI at the PDCCH monitoring opportunity corresponding to the indicated spatial information set. In this way, based on the link quality between the terminal device and the network device, if the link quality is poor when the terminal device and the network device communicate directly, or if the link quality is good when the network device and the terminal device communicate through the first device, the first device reflects or refracts the signal transmitted between the network device and the terminal device, thereby ensuring both communication transmission quality and paging accuracy.

[0333] In an embodiment of the present application, when the terminal device determines that the link quality between it and the network device is greater than the quality threshold, it indicates that the channel transmission quality between the terminal device and the network device is good. At this time, it can be considered that the terminal device and the network device communicate directly without forwarding through the first device. Furthermore, even if the paging configuration information indicates the first spatial information set or the second spatial information set, the terminal device can still determine the paging resource as the third paging resource corresponding to the third spatial information set broadcast by the network device. At this time, the terminal device uses the PDCCH listening opportunity corresponding to the third paging resource to listen to the P-RNTI-scrambled PDCCH. In this way, according to the link quality between the terminal device and the network device, when the link quality is good when the terminal device and the network device communicate directly, the terminal device communicates directly with the network device, thereby ensuring the communication transmission quality and the accuracy of paging.

[0334] In some embodiments, the link quality between the terminal device and the network device determined by the terminal device may be the link quality obtained by the terminal device based on downlink reference signal measurements, or the link quality determined by the network device based on uplink reference signal measurements.

[0335] In an embodiment of the present application, the link quality sent by the network device may be a measurement result of the service cell where the terminal device is located obtained by the terminal device based on the measurement configuration information sent by the network device.

[0336] In an embodiment of the present application, the terminal device determines the link quality based on the paging configuration message, which can be understood as the terminal device determining the link quality by determining at least one of the reference signal received power, reference signal received quality, signal to noise ratio, and signal to interference and noise ratio of the received paging configuration message.

[0337] In some embodiments, the paging configuration information includes first indication information, where the first indication information is used to indicate the first spatial information set or the second spatial information set, and the paging resource is the first paging resource or the second paging resource.

[0338] In an embodiment of the present application, the network device configures the first indication information in the paging configuration information to indicate the first spatial information set or the second spatial information set, and the terminal device determines the paging resource based on the first indication information used to indicate the first spatial information set or the second spatial information set.

[0339] Here, the paging resource may be determined by the terminal device based only on the first indication information.

[0340] In an embodiment of the present application, the first indication information is used to indicate a first spatial information set or a second spatial information set, representing that the terminal device communicates with the network device through the first device, that is, the spatial information set for communication between the terminal device and the first device is included in the first spatial information set or the second spatial information set. The terminal device monitors the PDCCH scrambled by the P-RNTI according to the PDCCH monitoring opportunity corresponding to the first spatial information set or the second spatial information set indicated by the first indication information, wherein the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the spatial information set indicated by the first indication information. In this way, after the introduction of the smart surface device, the terminal device can determine that the network device and the terminal device establish a communication link through the smart surface device based only on the first indication information in the paging configuration information sent by the network device. Furthermore, the terminal device uses the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the communication transmission quality while ensuring the accuracy of the paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0341] In some embodiments, when the first indication information indicates the first spatial information set, the paging resource is a first paging resource corresponding to the first spatial information set.

[0342] In an embodiment of the present application, when a terminal device communicates with a network device through a first device, if the first indication information in the paging configuration information sent by the network device indicates a first spatial information set, the terminal device can determine that the spatial information set forwarded by the first device is included in the first spatial information set, and determine that the paging resource is the first paging resource corresponding to the first spatial information set. At this time, the terminal device monitors the P-RNTI-scrambled PDCCH according to the PDCCH monitoring opportunity corresponding to the first spatial information set indicated by the first indication information, wherein the number of PDCCH monitoring opportunities is associated with the number of spatial information in the first spatial information set indicated by the first indication information. In this way, after the introduction of the smart surface device, when the first indication information indicates the first spatial information set, since the first spatial information set is part or all of the union of the second spatial information set forwarded by the smart surface device to the terminal device and the third spatial information set broadcast by the network device, and the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the first spatial information set indicated by the first indication information, the terminal device increases the number of blind detections so that it can monitor the paging message at the appropriate time, thereby improving the communication transmission quality while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0343] It should be noted that, since the terminal device communicates with the network device through the first device, the terminal device only needs to monitor the P-RNTI-scrambled PDCCH repeatedly sent based on the spatial information in the second spatial information set contained in the first spatial information set; but since the first spatial information set also includes the third spatial information set, the terminal device also needs to monitor the P-RNTI-scrambled PDCCH repeatedly sent based on the spatial information in the third spatial information set; therefore, the terminal device increases the number of blind detections during the monitoring process.

[0344] For example, as shown in FIG6 , FIG6 is a schematic diagram illustrating how a paging occasion (PO) corresponds to a first spatial information set. Exemplarily, the first spatial information set is the union of a second spatial information set and a third spatial information set. The second spatial information set includes spatial information 0, spatial information 1, spatial information 2, and spatial information 3, and the third spatial information set includes spatial information 4, spatial information 5, spatial information 6, and spatial information 7. Spatial information 0, spatial information 1, spatial information 2, and spatial information 3 are different from spatial information 4, spatial information 5, spatial information 6, and spatial information 7. Therefore, the first spatial information set includes spatial information 0, spatial information 1, spatial information 2, spatial information 3, spatial information 4, spatial information 5, spatial information 6, and spatial information 7. Each spatial information corresponds to a PDCCH monitoring opportunity (PMO), i.e., spatial information 0 corresponds to PMO 0, spatial information 1 corresponds to PMO 1, spatial information 2 corresponds to PMO 2, spatial information 3 corresponds to PMO 3, spatial information 4 corresponds to PMO 4, spatial information 5 corresponds to PMO 5, spatial information 6 corresponds to PMO 6, and spatial information 7 corresponds to PMO 7. As shown in Figure 6, the paging resource corresponding to the PO monitored by the terminal device can be the first paging resource corresponding to the first spatial information set, that is, the terminal device blindly detects a paging opportunity PO corresponding to each spatial information in the first spatial information set and repeatedly sends the P-RNTI-encrypted PDCCH, thereby monitoring the paging.

[0345] In some embodiments, when the first indication information indicates the second spatial information set, the paging resource is a second paging resource corresponding to the second spatial information set.

[0346] In an embodiment of the present application, if the first indication information in the paging configuration information sent by the network device indicates the second spatial information set, indicating that the network device communicates with the terminal device through the first device, when the terminal device receives the paging configuration information, it can determine that the spatial information set forwarded by the first device is the second spatial information set, and determine that the paging resource is the second paging resource corresponding to the second spatial information set. At this time, the terminal device monitors the P-RNTI-scrambled PDCCH according to the PDCCH monitoring opportunity corresponding to the second spatial information set indicated by the first indication information, wherein the number of PDCCH monitoring opportunities is associated with the number of spatial information in the second spatial information set indicated by the first indication information. In this way, after the introduction of the smart surface device, when the first indication information indicates the second spatial information set, since the second spatial information set is the second spatial information set forwarded by the smart surface device to the terminal device, and the number of PDCCH monitoring opportunities corresponds to the number of spatial information in the second spatial information set indicated by the first indication information, compared with the first indication information indicating the first spatial information set, the terminal device can reduce unnecessary blind detections received by the terminal device. At the same time, the terminal device can also enable itself to monitor the paging message at the appropriate time, thereby improving the communication transmission quality and not increasing the number of blind detections, while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0347] It should be noted that since the network device communicates with the terminal device through the first device, the terminal device only needs to detect the P-RNTI-scrambled PDCCH repeatedly sent by the spatial information in the second spatial information set corresponding to the first device to determine the paging message, and does not need to additionally detect the PDCCH monitoring timing corresponding to other spatial information; therefore, the terminal device does not need to increase the number of blind detections of the terminal device during the monitoring process, thereby reducing the terminal device from receiving unnecessary paging.

[0348] Exemplarily, referring to FIG7 , FIG7 is a schematic diagram of a paging opportunity PO corresponding to a second spatial information set, wherein, exemplarily, the second spatial information set includes spatial information 4, spatial information 5, spatial information 6, and spatial information 7, each of which corresponds to a PDCCH monitoring opportunity (PMO), that is, spatial information 4 corresponds to PMO4, spatial information 5 corresponds to PMO5, spatial information 6 corresponds to PMO6, and spatial information 7 corresponds to PMO7. Referring to FIG7 , the paging resource corresponding to the PO detected by the terminal device may be the second paging resource corresponding to the second spatial information set, and the paging resource corresponding to the PO detected by the terminal device may be the second paging resource corresponding to the second spatial information set, that is, the terminal device blindly detects a paging opportunity PO corresponding to the PDCCH scrambled by repeatedly sending the P-RNTI based on each spatial information in the second spatial information set.

[0349] In some embodiments, the paging configuration information includes first indication information, and the first indication information is also used to indicate a third spatial information set; when the first indication information indicates the third spatial information set, the paging resource is a third paging resource; or, when the paging configuration information does not include the first indication information, the paging resource is a third paging resource.

[0350] Here, the paging resource can be determined by the terminal device only based on the first indication information, and the first indication information is an optional configuration.

[0351] In an embodiment of the present application, the network device configures the first indication information in the paging configuration information to indicate the third spatial information set, or the network device does not configure the first indication information in the paging configuration information, or the network device does not include the first indication information when configuring the paging configuration information. At this time, the terminal device determines the paging resource based on the first indication information used to indicate the third spatial information set, or the terminal device determines the paging resource based on the paging configuration information that does not include the first indication information, or the terminal device determines the paging resource based on the unconfigured first indication information.

[0352] In an embodiment of the present application, the first indication information is used to indicate the third spatial information set, indicating that the network device can communicate directly with the terminal device without forwarding by the first device. After the network device sends the paging configuration information to the terminal device, the terminal device can determine that the spatial information set communicating with the network device is included in the third spatial information set, and determine that the paging resource is the third paging resource corresponding to the third spatial information set. At this time, the terminal device blindly detects a paging opportunity PO corresponding to the spatial information in the third spatial information set and repeatedly sends the P-RNTI-encrypted PDCCH. In this way, after the introduction of the smart surface device, when the first indication information indicates the third spatial information set, the terminal device can determine that the network device and the terminal device directly establish a communication link. Furthermore, the terminal device uses the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the quality of communication transmission while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0353] It should be noted that when the first indication information is not configured in the paging configuration information, or the first indication information in the paging configuration information is absent, the terminal device can determine that the spatial information set for communicating with the network device is the third spatial information set, wherein the third spatial information set can be the spatial information included in the parameter ssb-PositionsInBurst in SIB1.

[0354] Exemplarily, referring to FIG8 , FIG8 is a schematic diagram of a paging opportunity PO corresponding to a third spatial information set, wherein, exemplarily, the third spatial information set includes spatial information 0, spatial information 1, spatial information 2, and spatial information 3, each of which corresponds to a PDCCH monitoring opportunity (PMO), i.e., spatial information 0 corresponds to PMO0, spatial information 1 corresponds to PMO1, spatial information 2 corresponds to PMO2, and spatial information 3 corresponds to PMO3. Referring to FIG8 , the paging resource corresponding to the PO detected by the terminal device may be the third paging resource corresponding to the third spatial information set, i.e., the terminal device blindly detects a paging opportunity PO corresponding to the PDCCH scrambled by repeatedly transmitting the P-RNTI based on each spatial information in the third spatial information set.

[0355] In some embodiments, if the paging configuration information only includes the first indication information, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0356] In an embodiment of the present application, an RRC release message or a specific signaling of a terminal device is a specific message configured by a network device for a terminal device. The RRC release message is used to indicate that the terminal device is transitioning from an RRC connected state to an RRC idle state or an RRC inactive state. The specific signaling of the terminal device may be a high-level signaling dedicated to the terminal device. The RRC release message or the specific signaling of the terminal device may be sent by the network device to the terminal device when the terminal device enters a connected state, thereby reducing the power consumption of the terminal device. In an embodiment of the present application, the network device carries the paging configuration information in the RRC release message or the specific signaling of the terminal device, and sends the RRC release message or the specific signaling of the terminal device to the terminal device, so that the terminal device monitors the paging PDCCH based on the paging configuration information.

[0357] Exemplarily, the paging configuration information is included in higher-layer signaling dedicated to the terminal device UE, such as an RRC release message or PDCCH-configcommon. For different terminal devices, the corresponding spatial information set may be different. Optionally, the paging configuration information may be carried in the dedicated signaling of the terminal device.

[0358] In some embodiments, the paging configuration information further includes second indication information, where the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information.

[0359] In an embodiment of the present application, the network device configures the first indication information to indicate the first spatial information set or the second spatial information set, and configures the second indication information to indicate whether to apply the spatial information set indicated by the first indication information, thereby obtaining paging configuration information and sending the paging configuration information to the terminal device. The terminal device determines the paging resources based on the first indication information and the second indication information.

[0360] In an embodiment of the present application, the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information. The data type of the second indication information can be an enumeration type or a Boolean type, and this embodiment of the present application does not impose any restrictions on this.

[0361] In an embodiment of the present application, the first indication information is used to indicate the first spatial information set and the second spatial information set, and the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information. After the network device sends paging configuration information including the first indication information and the second indication information to the terminal device, the terminal device determines the paging resource based on the first indication information for indicating the first spatial information set and the first indication information for indicating the application of the spatial information set indicated by the first indication information; or

[0362] The terminal device determines the paging resource based on the first indication information used to indicate the first spatial information set and the first indication information used to indicate that the spatial information set indicated by the first indication information should not be applied; or,

[0363] The terminal device determines the paging resource based on the first indication information used to indicate the second spatial information set and the spatial information set indicated by the first indication information used to indicate the application; or,

[0364] The terminal device determines the paging resource based on the first indication information used to indicate the second spatial information set and the first indication information used to indicate that the spatial information set indicated by the first indication information should not be applied.

[0365] It should be noted that due to the mobility of the terminal device, when the network device configures the paging configuration information, it needs to be configured according to whether the terminal device is located in the area provided by the first device. If the communication performance of the terminal device through the first device and the network device is better, and in other areas, the communication performance of the terminal device directly connected to the network device is better, then the network device can indicate the spatial information set again through the second indication information, so that the terminal device can jointly determine the paging resources through the combination of the first indication information and the second indication information; in this way, the terminal device can select the paging resources corresponding to the appropriate spatial information set according to the distance between the terminal device and the network device to monitor the paging message, and then can monitor the paging message at the appropriate time.

[0366] In some embodiments, the paging configuration information further includes second indication information. When the number of bits corresponding to the second indication information is the first number, if the second indication information is the first value, the paging resource is the first paging resource or the second paging resource; if the second indication information is the second value, the paging resource is the third paging resource; or,

[0367] When the number of bits corresponding to the second indication information is the second number, if the second indication information is the third value, the paging resource is the first paging resource; if the second indication information is the fourth value, the paging resource is the second paging resource; if the second indication information is the fifth value, the paging resource is the third paging resource;

[0368] The first quantity is different from the second quantity.

[0369] In an embodiment of the present application, the number of bits corresponding to the second indication information can be a first number such as 1, and the number of bits corresponding to the second indication information can also be a second number such as 2. Of course, the number of bits corresponding to the second indication information can also be other numbers other than the first number and the second number, such as 3, 4, 5, etc., and the embodiment of the present application does not impose any restrictions on this.

[0370] In an embodiment of the present application, the second indication information may indicate whether to apply the spatial information set indicated by the first indication information. The second indication information may also indicate the first spatial information set, the second spatial information set, or the third spatial information set. The second indication information may be represented by different values. Here, the second indication information may be the first value, the second value, the third value, the fourth value, or the fifth value.

[0371] In this embodiment of the present application, the first value may indicate the first spatial information set or the second spatial information set, and may also indicate that the spatial information set indicated by the first indication information is applied. The second value may indicate the third spatial information set, and may also indicate that the spatial information set indicated by the first indication information is not applied.

[0372] In an embodiment of the present application, the third value may indicate the first spatial information set, the fourth value may indicate the second spatial information set, and the fifth value may indicate the third spatial information set; of course, the third value and the fourth value may also indicate the application of the spatial information set indicated by the first indication information, and the fifth value may also indicate that the spatial information set indicated by the first indication information is not applied.

[0373] Exemplarily, when the number of bits corresponding to the second indication information is the first number, the first value may be 0 and the second value may be 1; or, the first value may be 1 and the second value may be 0.

[0374] Exemplarily, when the number of bits corresponding to the second indication information is the second number, the third value can be 00, the fourth value can be 01, and the fifth value can be 10; or, the third value can be 00, the fourth value can be 10, and the fifth value can be 11, or, the third value can be 00, the fourth value can be 01, the fifth value can be 10, and so on. It should be noted that when the number of bits corresponding to the second indication information is the second number, there can be multiple combinations between the third value, the fourth value and the fifth value, and this application does not enumerate them all.

[0375] Exemplarily, when the number of bits corresponding to the second indication information is another number such as 3, the third value can be 000, the fourth value can be 001, and the fifth value can be 100; or, the third value can be 000, the fourth value can be 010, and the fifth value can be 101, or, the third value can be 010, the fourth value can be 010, the fifth value can be 100, and so on. It should be noted that when the number of bits corresponding to the second indication information is the third number, there can be multiple combinations between the third value, the fourth value and the fifth value, and this application does not enumerate them all.

[0376] In an embodiment of the present application, when the number of bits corresponding to the second indication information is the first number, if the second indication information is the first value, the first value indicates the first spatial information set or the second spatial information set, or the first value indicates the spatial information set indicated by the first indication information, the paging resource is the first paging resource corresponding to the first spatial information set or the second paging resource corresponding to the second spatial information set; if the second indication information is the second value, the second value indicates the third spatial information set, and the paging resource is the third paging resource corresponding to the third spatial information set.

[0377] It should be noted that due to the mobility of the terminal device, when the network device configures the paging configuration information, it needs to be configured according to whether the terminal device is located in the area provided by the first device. If the communication performance of the terminal device through the first device and the network device is better, and in other areas, the communication performance of the terminal device directly connected to the network device is better, then the network device can indicate the spatial information set again through the second indication information, so that the terminal device can jointly determine the paging resources through the combination of the first indication information and the second indication information; in this way, the terminal device can select the paging resources corresponding to the appropriate spatial information set according to the distance between the terminal device and the network device to monitor the paging message, and then can monitor the paging message at the appropriate time.

[0378] In an embodiment of the present application, when the number of bits corresponding to the second indication information is the second number, if the second indication information is a third value, the third value indicates the first spatial information set, and the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is a fourth value, the fourth value indicates the second spatial information set, and the paging resource is the second paging resource corresponding to the second spatial information set; if the second indication information is a fifth value, the fifth value indicates the third spatial information set, and the paging resource is the third paging resource corresponding to the second spatial information set.

[0379] It should be noted that due to the mobility of the terminal device, when the network device configures the paging configuration information, it needs to be configured according to whether the terminal device is located in the area provided by the first device. If the communication performance of the terminal device through the first device and the network device is better, and in other areas, the communication performance of the terminal device directly connected to the network device is better, then the network device can indicate the spatial information set again through the second indication information, so that the terminal device can jointly determine the paging resources through the combination of the first indication information and the second indication information; in this way, the terminal device can select the paging resources corresponding to the appropriate spatial information set according to the distance between the terminal device and the network device to monitor the paging message, and then can monitor the paging message at the appropriate time.

[0380] In some embodiments, when the second indication information indicates to apply the spatial information set indicated by the first indication information, the second indication information is the first value or the third value;

[0381] When the second indication information indicates that the spatial information set indicated by the first indication information is not to be applied, the second indication information is the second value, the fourth value or the fifth value.

[0382] In an embodiment of the present application, the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information. Here, when the second indication information indicates to apply the spatial information set indicated by the first indication information, the second indication information is the first value or the third value; that is, the first value and the third value are used to indicate to apply the spatial information set indicated by the first indication information. When the second indication information indicates not to apply the spatial information set indicated by the first indication information, the second indication information is the second value, the fourth value, or the fifth value; that is, the second value, the fourth value, and the fifth value are used to indicate not to apply the spatial information set indicated by the first indication information.

[0383] In an embodiment of the present application, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, when the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information, and the second indication information is the first value or the third value (the first value and the third value indicate the application of the spatial information set indicated by the first indication information), then, based on the first indication information and the second indication information, the terminal device determines that the first paging resource corresponding to the first spatial information set is the paging resource, or determines that the paging resource corresponding to the second spatial information is the paging resource.

[0384] In an embodiment of the present application, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, when the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is used to indicate whether to apply the spatial information set indicated by the first indication information, and the second indication information is the second value, the fourth value or the fifth value (the second value, the fourth value and the fifth value indicate that the spatial information set indicated by the first indication information is not applied), then, based on the first indication information and the second indication information, the terminal device determines that the third paging resource corresponding to the third spatial information set is the paging resource, and thereby monitors the paging message based on the third paging resource.

[0385] In some embodiments, when the first indication information indicates the first spatial information set, if the second indication information is the first value or the third value, the paging resource is the first paging resource; or,

[0386] In the case where the first indication information indicates the second spatial information set, if the second indication information is the first value or the fourth value, the paging resource is the second paging resource; if the second indication information is the third value, the paging resource is the first paging resource;

[0387] In a case where the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is the second value or the fifth value, the paging resource is the third paging resource.

[0388] In an embodiment of the present application, the first value, the second value, the third value, the fourth value, and the fifth value all indicate a spatial information set. When the first value, the second value, the third value, the fourth value, and the fifth value all indicate a spatial information set, the network device may further indicate in the paging configuration information that the priority of the second indication information is higher than the priority of the first indication information. After the network device sends the paging configuration information to the terminal device, if the spatial information set indicated by the first indication information is completely inconsistent with the spatial information set indicated by the second indication information, the priority of the second indication information is higher than the priority of the first indication information, and the terminal device determines the paging resource based on the second indication information. If the spatial information set indicated by the first indication information is not completely consistent with the spatial information set indicated by the second indication information, the terminal device determines, based on the first indication information and the second indication information, that the paging resource corresponding to the spatial information set indicated by both the first indication information and the second indication information is the paging resource.

[0389] In a first possible implementation method, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, if the first indication information indicates the first spatial information set, the second indication information is a first value indicating the first spatial information set or the second spatial information set, or the second indication information is a third value indicating the first spatial information set, since the spatial information set indicated by the first indication information is not completely consistent with the spatial information set indicated by the second indication information, and both the first indication information and the second indication information indicate the first spatial information set, at this time, the terminal device determines, based on the first indication information and the second indication information, that the first paging resource corresponding to the first spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0390] In a second feasible manner, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, if the first indication information indicates the second spatial information set, the second indication information is a first value indicating the first spatial information set or the second spatial information set, or the second indication information is a fourth value indicating the second spatial information set, since the spatial information set indicated by the first indication information is not completely consistent with the spatial information set indicated by the second indication information, and both the first indication information and the second indication information indicate the second spatial information set, after the network device sends the paging configuration information to the terminal device, the terminal device determines, based on the first indication information and the second indication information, that the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0391] In a third achievable method, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, if the first indication information indicates the first spatial information set, or the first indication information indicates the second spatial information set, the second indication information is the second value indicating the third spatial information set, or the second indication information is the fifth value indicating the third spatial information set, since the spatial information set indicated by the first indication information is completely inconsistent with the spatial information set indicated by the second indication information, and the priority of the second indication information is higher than the priority of the first indication information, at this time, the terminal device determines, based on the second indication information, that the third paging resource corresponding to the third spatial information set indicated by the second indication information is the paging resource.

[0392] In some embodiments, when the first value, the second value, the third value, the fourth value, and the fifth value all indicate spatial information sets, the determination of the paging resource is further associated with the configuration of the first spatial information set and the second spatial information set.

[0393] In one implementation, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, if the configuration of the first spatial information set is associated with the number of actually transmitted spatial information contained in the first spatial information set, then, when the first indication information indicates the first spatial information set, if the second indication information is a first value having a first number of bits, wherein the first value indicates the first spatial information set or the second spatial information set, or the second indication information is a third value having a second number of bits, wherein the third value indicates the first spatial information set, then the terminal device determines that the first paging resource corresponding to the first spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0394] In another possible implementation, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, if the configuration of the second spatial information set is associated with the number of actually transmitted spatial information contained in the second spatial information set, then, when the first indication information indicates the second spatial information set, if the second indication information is a first value having a first number of bits, wherein the first value indicates the first spatial information set or the second spatial information set, or the second indication information is a fourth value having a second number of bits, wherein the fourth value indicates the second spatial information set, then the terminal device determines that the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0395] In another possible implementation, after the network device sends paging configuration information including first indication information and second indication information to the terminal device, if the configuration of the second spatial information set is associated with the amount of spatial information actually transmitted contained in the second spatial information set and the amount of spatial information actually transmitted contained in the third spatial information set, then, when the first indication information indicates the second spatial information set, the terminal device determines that the paging resource exists in the following two situations:

[0396] Case 1: If the second indication information is a first value having a first number of bits, wherein the first value indicates the first spatial information set or the second spatial information set, or the second indication information is a fourth value having a second number of bits, wherein the fourth value indicates the second spatial information set, after the network device sends the paging configuration information to the terminal device, the terminal device determines that the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information is the paging resource.

[0397] Case 2: If the second indication information is a third value having a second number of bits, where the third value indicates the first spatial information set, since the second spatial information set includes the second spatial information set and the third spatial information set during the configuration process, and the priority of the second indication information is higher than the priority of the first indication information, after the network device sends the paging configuration information to the terminal device, the terminal device determines that the first paging resource corresponding to the first spatial information set indicated by the second indication information is the paging resource.

[0398] For example, the number of bits corresponding to the second indication information is 1, the first value is 0, and the second value is 1; the number of bits corresponding to the second indication information is 2, the third value is 00, the fourth value is 01, and the fifth value is 10.

[0399] After the network device sends paging configuration information including first indication information and second indication information to the terminal device, in the case where the second indication information is a first value, a second value, a third value, a fourth value and a fifth value all indicating a spatial information set, if the first indication information indicates the first spatial information set and the second indication information is a first value (0) or a third value (00), since the first value (0) indicates the first spatial information set or the second spatial information set and the third value (00) indicates the first spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is a second value (1) or a fifth value (10), since the second value (1) and the fifth value (10) both indicate the third spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0400] After the network device sends paging configuration information including first indication information and second indication information to the terminal device, in the case where the first value, the second value, the third value, the fourth value and the fifth value all indicate the spatial information set, if the first indication information indicates the second spatial information set, the second indication information is the first value (0) or the fourth value (01), since the first value (0) indicates the first spatial information set or the second spatial information set and the fourth value (01) indicates the second spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the second paging resource corresponding to the second spatial information set; if the second indication information is the third value (00), since the third value (00) indicates the first spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is the second value (1) or the fifth value (10), since the second value (1) and the fifth value (10) both indicate the third spatial information set, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0401] After a network device sends paging configuration information including first indication information and second indication information to a terminal device, in the case where the second indication information is a first value, a second value, a third value, a fourth value, and a fifth value indicating whether to apply a spatial information set indicated by the first indication information, if the first indication information indicates the first spatial information set, the second indication information is a first value (0) or a third value (00), since the first value (0) and the third value (00) both indicate that the spatial information set indicated by the first indication information is applied, the terminal device determines, based on the second indication information, that the paging resource is the first paging resource corresponding to the first spatial information set; if the second indication information is a second value (1), a fourth value (01), or a fifth value (10), since the second value (1), the fourth value (01), and the fifth value (10) both indicate that the spatial information set indicated by the first indication information is not applied, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0402] After a network device sends paging configuration information including first indication information and second indication information to a terminal device, in the case where the second indication information is a first value, a second value, a third value, a fourth value, and a fifth value indicating whether to apply a spatial information set indicated by the first indication information, if the first indication information indicates the second spatial information set, the second indication information is a first value (0) or a third value (00), since the first value (0) and the third value (00) both indicate that the spatial information set indicated by the first indication information is applied, the terminal device determines, based on the second indication information, that the paging resource is the second paging resource corresponding to the second spatial information set; if the second indication information is a second value (1), a fourth value (01), or a fifth value (10), since the second value (1), the fourth value (01), and the fifth value (10) both indicate that the spatial information set indicated by the first indication information is not applied, the terminal device determines, based on the second indication information, that the paging resource is the third paging resource corresponding to the third spatial information set.

[0403] In some embodiments, when the paging configuration information includes the second indication information, the first indication information is carried in the dedicated signaling of the serving cell where the terminal device is located, and the second indication information is carried in the radio resource control RRC release message or the dedicated signaling of the terminal device; or, the first indication information and the second indication information are carried in the RRC release message or the dedicated signaling of the terminal device;

[0404] In the case that the paging configuration information does not include the second indication information, the first indication information is carried in the RRC release message or the dedicated signaling of the terminal device.

[0405] In the embodiment of the present application, the paging configuration information includes first indication information and second indication information. The first indication information and the second indication information can be carried in the same signaling or different signaling.

[0406] Here, the first indication information and the second indication information are carried in different signalings, which can be understood as the first indication information can be carried in the dedicated signaling of the service cell where the terminal device is located, and the second indication information can be carried in the RRC release message or the dedicated signaling of the terminal device.

[0407] It should be noted that since the priority of the second indication information is higher than that of the first indication information, the second indication information can be carried in the RRC release message or the dedicated signaling of the terminal device, and the first indication information can be carried in the dedicated signaling of the service cell where the terminal device is located.

[0408] Exemplarily, the first indication information is carried in a system message such as a SIB1 message or PDCCH-configcommon, and the second indication information can be carried in an RRC release message or a dedicated signaling of the terminal device, thereby ensuring the accuracy of the paging configuration information received by the terminal device.

[0409] Here, the first indication information and the second indication information are carried in the same signaling, which can be understood as the first indication information and the second indication information are both carried in the RRC release message or the dedicated signaling of the terminal device. Exemplarily, the first indication information and the second indication information can be carried in the RRC release message or the dedicated signaling of the terminal device, so as to ensure the accuracy of the paging configuration information received by the terminal device.

[0410] In some embodiments, the paging configuration information further includes third indication information, and the third indication information is used to configure the first timer.

[0411] In an embodiment of the present application, the network device configures the first indication information to indicate the first spatial information set or the second spatial information set, and configures the third indication information to the first timer, thereby obtaining paging configuration information and sending the paging configuration information to the terminal device.

[0412] In an embodiment of the present application, the first timer is used to determine different time ranges, wherein the different time ranges include a range during which the first timer is running or a start time range, a range during which the first timer is not running, or a timeout time range.

[0413] In an embodiment of the present application, after a network device sends paging configuration information including first indication information and third indication information to a terminal device, the terminal device determines whether the paging resource is the first paging resource, the second paging resource, or the third paging resource based on the first indication information indicating the first spatial information set or the second spatial information set, and whether the first timer is running within the corresponding time range. In this way, the network device configures the first indication information to indicate the spatial information set, and configures the spatial information sets corresponding to different time ranges of the first timer in the second indication information, so that the terminal device determines the paging resource based on the first indication information and the third indication information, and thus monitors the paging message on the paging resource.

[0414] In some embodiments, after the network device sends paging configuration information including the first indication information and the second indication information to the terminal device, the terminal device determines the paging resource based on the first indication information and the first timer, which can be implemented as follows:

[0415] When the first indication information indicates the first spatial information set or the second spatial information set, during the operation of the first timer, the paging resource is the first paging resource corresponding to the first spatial information set or the second paging resource corresponding to the second spatial information set; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0416] In an embodiment of the present application, if the first indication information indicates the first spatial information set or the second spatial information set, and the first timer is in operation or in the start time range, the terminal device determines that the paging resource is the first paging resource corresponding to the first spatial information set or the second paging resource corresponding to the second spatial information set, and monitors the paging message on the first paging resource or the second paging resource. In this way, when the first indication information indicates the spatial information set, the paging resource is determined by the spatial information set corresponding to different time ranges (i.e., the timer start time range or the time range in which the timer is not started or has timed out), thereby monitoring the paging on the paging resource.

[0417] In some embodiments, after the network device sends paging configuration information including the first indication information and the second indication information to the terminal device, the terminal device determines the paging resource based on the first indication information and the first timer, which can be implemented as follows:

[0418] When the first indication information indicates the first spatial information set, the paging resource is the first paging resource during the running of the first timer; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0419] When the first indication information indicates the second spatial information set, the paging resource is the second paging resource during the running of the first timer; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0420] In an embodiment of the present application, after the network device sends paging configuration information including the first indication information and the second indication information to the terminal device, if the first indication information indicates the first spatial information set and the first timer is in operation or in the start time range, the terminal device determines that the paging resource is the first paging resource corresponding to the first spatial information set, and monitors the paging message on the first paging resource. If the first indication information indicates the first spatial information set and the first timer is not running or has timed out, the terminal device determines that the paging resource is the third paging resource corresponding to the third spatial information set, and monitors the paging message on the third paging resource. In this way, when the first indication information indicates the first spatial information set, the paging resource is determined by the spatial information set corresponding to different time ranges (i.e., the timer start time range or the time range in which the timer is not started or has timed out), thereby monitoring the paging message on the paging resource.

[0421] In an embodiment of the present application, after the network device sends paging configuration information including the first indication information and the second indication information to the terminal device, if the first indication information of the terminal device indicates the second spatial information set and the first timer is in operation or in the start time range, the terminal device determines that the paging resource is the second paging resource corresponding to the second spatial information set, and monitors the paging message on the second paging resource. If the first indication information indicates the second spatial information set and the first timer is not running or has timed out, the terminal device determines that the paging resource is the third paging resource corresponding to the third spatial information set, and monitors the paging message on the third paging resource. In this way, when the first indication information indicates the second spatial information set, the paging resource is determined by the spatial information set corresponding to different time ranges (i.e., the timer start time range or the time range in which the timer is not started or has timed out), thereby monitoring the paging message on the paging resource.

[0422] For example, referring to FIG9 , FIG9 is a schematic diagram of determining a spatial information set corresponding to a paging opportunity PO based on a timer. Taking the first indication information indicating the second spatial information set as an example, during the operation of the first timer, the spatial information set corresponding to the paging opportunity PO1 is the second spatial information set. At this time, the terminal device monitors the paging message on the second paging resource corresponding to the second spatial information set. When the first timer is not running or times out, the spatial information set corresponding to the paging opportunity PO2 is the third spatial information set. At this time, the terminal device monitors the paging message on the third paging resource corresponding to the third spatial information set. In this way, the terminal device can receive the paging message at the appropriate time based on the timer.

[0423] In some embodiments, the configuration of the first timer is associated with information related to the mobility of the terminal device, where the information related to the mobility of the terminal device includes one or more of the following:

[0424] The location of the terminal equipment;

[0425] The speed of the terminal device;

[0426] Movement patterns of terminal equipment;

[0427] Movement direction of the terminal device;

[0428] The timestamp corresponding to the terminal device's location.

[0429] In an embodiment of the present application, the position of the terminal device indicates whether the terminal device is located in the area provided by the first device during paging. If the terminal device is located in the service area provided by the first device, the terminal device communicates with the network device through the first device. If the terminal device is not in the service area provided by the first device, the terminal device communicates directly with the network device. That is, the position of the terminal device determines whether the terminal device communicates with the network device through the first device or directly with the network device. Therefore, the network device selects a communication method according to the position of the terminal device, and then dynamically allocates different spatial information sets to different time ranges of the first timer according to the selected communication method, so that the terminal device can monitor the paging message at the appropriate time. For example, when the UE is in position 1, it can communicate directly with the network device, that is, there is no need for the first device to forward the signal, and the paging resources can be the paging resources corresponding to the third spatial information set; when the UE moves to position 2, because there is an obstruction between it and the network device, it communicates with the network device through the first device, and the paging resources can be the paging resources corresponding to the first spatial information set or the second spatial information set.

[0430] In an embodiment of the present application, the speed of the terminal device determines the movement time of the terminal device in the area provided by the first device and / or the network device during paging. The movement time used by the terminal device can determine the running time of the first timer, so that the network device dynamically allocates different spatial information sets to different time ranges of the first timer, so that the terminal device can monitor the paging message at the appropriate time.

[0431] In an embodiment of the present application, the movement pattern of the terminal device means that the movement trajectory pattern of the terminal device in the area provided by the first device or the network device is taken into consideration during paging. Based on the movement trajectory pattern, the time domain in which the terminal device can communicate directly with the network device can be determined, as well as the time domain in which the terminal device needs to communicate with the network device through the first device. The network device dynamically allocates different spatial information sets to different time ranges of the first timer, so that the terminal device can monitor the paging message at the appropriate time.

[0432] In an embodiment of the present application, the movement direction of the terminal device indicates that the movement direction of the terminal device in the area provided by the first device or the network device is considered in the paging. Based on the movement direction, the time domain in which the terminal device can communicate directly with the network device can be determined, and the time domain in which the terminal device needs to communicate with the network device through the first device can be determined. Therefore, the network device dynamically allocates different spatial information sets to different time ranges of the first timer, so that the terminal device can monitor the paging message at the appropriate time.

[0433] It should be noted that since the setting of the first timer is closely related to the mobility of the terminal device, it is necessary to know the movement trajectory of the terminal device. Based on the movement trajectory, the time domain in which the terminal device can communicate directly with the network device and the time domain in which the terminal device communicates with the network device through the first device are determined, so that the network device dynamically allocates different spatial information sets to different time ranges of the first timer.

[0434] It can be understood that due to mobility, the terminal device will receive a paging message in the paging resources corresponding to the third spatial information set in a certain area, and receive a paging message in the paging resources corresponding to the first spatial information set or the second spatial information set in another area. For example, the terminal device is located in the first area, and the terminal device receives a paging message in the paging resources corresponding to the third SSB set. The terminal device is located in the second area, and the terminal device receives a paging message in the paging resources corresponding to the first SSB set or the second SSB set. The time taken by the terminal device to move from the first area to the second area can be the time range of the first timer.

[0435] It can be understood that when configuring the spatial information set according to the first timer, since the terminal device corresponds to different spatial information sets in different time ranges, it is necessary to consider the impact of the terminal device's mobility on the terminal device's monitoring of paging messages, so that the terminal device can receive the paging message at the appropriate time.

[0436] In some embodiments, if the paging configuration information includes the first indication information and the third indication information, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0437] In an embodiment of the present application, the RRC release message or the specific signaling of the terminal device is a specific message configured by the network device for the terminal device. The network device sends the first indication information and the third indication information in the paging configuration information carried by the RRC release message or the specific signaling of the terminal device to the terminal device, so that the terminal device monitors the paging PDCCH.

[0438] In some embodiments, the paging configuration information further includes fourth indication information, and the fourth indication information is used to configure the spatial information set pattern.

[0439] Here, the spatial information set pattern is associated with one or more of the following:

[0440] Radio frame PF of the terminal device;

[0441] PO in the PF of the terminal device;

[0442] Time domain subframe configuration of the terminal device.

[0443] Here, different PFs in a discontinuous reception DRX cycle in the spatial information set pattern correspond to different spatial information sets;

[0444] Different POs in a PF within a DRX cycle in the spatial information set pattern correspond to different spatial information sets;

[0445] Different subframes in the system frame included in the spatial information set pattern correspond to different spatial information sets.

[0446] In an embodiment of the present application, a terminal device is provided with a plurality of radio frames PF for receiving paging messages in a discontinuous period DRX cycle, and each radio frame PF corresponds to a plurality of paging occasions PO.

[0447] In the embodiment of the present application, different PFs in a discontinuous reception DRX cycle in the spatial information set pattern may correspond to the same or different spatial information sets. That is, the spatial information sets corresponding to different PFs may be the same, or the spatial information sets corresponding to different PFs may be different, but the spatial information sets corresponding to different POs in the same PF are the same.

[0448] Exemplarily, the number of PFs monitored by the terminal device within a DRX cycle is 2. At this time, the network device configures the spatial information set corresponding to the first PF as the second spatial information set, and configures the spatial information set corresponding to the second PF as the third spatial information set, that is, the spatial information sets corresponding to different PFs are different, and the spatial information sets corresponding to different POs in the same PF are the same.

[0449] In another example, the number of PFs monitored by the terminal device within a DRX cycle is 4. At this time, the network device configures the spatial information set corresponding to the first PF as the first spatial information set, configures the spatial information set corresponding to the second PF as the second spatial information set, configures the spatial information set corresponding to the third PF as the third spatial information set, and configures the spatial information set corresponding to the fourth PF as the second spatial information set; that is, the spatial information sets corresponding to different PFs may be the same or different, and the spatial information sets corresponding to different POs in the same PF are the same.

[0450] In an embodiment of the present application, different POs within a PF within a DRX cycle in the spatial information set pattern may correspond to the same or different spatial information sets, that is, the spatial information sets corresponding to different POs may be the same, or the spatial information sets corresponding to different POs may be different.

[0451] Exemplarily, the number of POs of the terminal device within a PF is 2, that is, the terminal device monitors paging messages at two POs within a PF. At this time, the network device configures the spatial information set corresponding to the first P0 as the second spatial information set, and configures the spatial information set corresponding to the second P0 as the third spatial information set, that is, different P0s correspond to different spatial information sets.

[0452] In another example, the number of POs of the terminal device in a PF is 4. At this time, the network device configures the spatial information set corresponding to the first PO as the first spatial information set, configures the spatial information set corresponding to the second PO as the second spatial information set, configures the spatial information set corresponding to the third PO as the third spatial information set, and configures the spatial information set corresponding to the fourth PO as the second spatial information set; that is, the spatial information sets corresponding to different POs can be the same or different.

[0453] In an embodiment of the present application, different subframes in the system frame included in the spatial information set pattern may correspond to the same or different spatial information sets. It should be noted that a system frame includes multiple subframes, such as 10 subframes. At this time, the network device configures the spatial information set corresponding to the first part of the subframe in the system frame as the second spatial information set, and configures the spatial information set corresponding to the second part of the subframe as the third spatial information set, wherein the first part of the subframe includes one or more subframes in the system frame, and the second part of the subframe includes other subframes in the system frame except the first part of the subframe; or, the spatial information set corresponding to the first part of the subframe in the system frame is the first spatial information set, the spatial information set corresponding to the second part of the subframe is the second spatial information set, and the spatial information set corresponding to the third part of the subframe is the third spatial information set, wherein the first part of the subframe, the second part of the subframe and the third part of the subframe are different, and the system frame includes the first part of the subframe, the second part of the subframe and the third part of the subframe. Here, since the beam set supported by the first device may be associated with the time domain subframe configuration, the beam sets supported by different one or more subframes may be different, and adjusting the spatial information set in a semi-static manner can reduce signaling overhead.

[0454] In some embodiments, the configuration of the spatial information set pattern is associated with information related to the mobility of the terminal device, wherein the information related to the mobility of the terminal device includes one or more of the following:

[0455] The location of the terminal equipment;

[0456] The speed of the terminal device;

[0457] Movement patterns of terminal equipment;

[0458] Movement direction of the terminal device;

[0459] The timestamp corresponding to the terminal device's location.

[0460] In an embodiment of the present application, the location of the terminal device indicates whether the terminal device is located in the area provided by the first device during paging. If the terminal device is located in the service area provided by the first device, the terminal device communicates with the network device through the first device. If the terminal device is not in the service area provided by the first device, the terminal device communicates directly with the network device. That is, the location of the terminal device determines whether the terminal device communicates with the network device through the first device or directly with the network device. Therefore, the network device selects a communication method according to the location of the terminal device, and then dynamically allocates different spatial information sets based on the spatial information set pattern according to the selected communication method, so that the terminal device can monitor the paging message at the appropriate time. For example, when the UE is in position 1, it can communicate directly with the network device, that is, without the need for the first device to forward the signal, and the paging resource can be the paging resource corresponding to the third spatial information set; when the UE moves to position 2, because there is an obstruction between it and the network device, it communicates with the network device through the first device, and the paging resource can be the paging resource corresponding to the first spatial information set or the second spatial information set.

[0461] In an embodiment of the present application, the speed of the terminal device determines the movement time of the terminal device in the area provided by the first device and / or the network device in the paging. The movement time of the terminal device determines the configuration of the spatial information set pattern, so that the network device dynamically allocates different spatial information sets based on the spatial information set pattern, so that the terminal device can monitor the paging message at the appropriate time.

[0462] In an embodiment of the present application, the movement pattern of the terminal device means that the movement trajectory pattern of the terminal device in the area provided by the first device or the network device is taken into consideration during paging. Based on the movement trajectory pattern, the time domain in which the terminal device can communicate directly with the network device can be determined, as well as the time domain in which the terminal device needs to communicate with the network device through the first device can be determined. Therefore, the network device dynamically allocates different spatial information sets based on the spatial information set pattern, so that the terminal device can monitor the paging message at the appropriate time.

[0463] In an embodiment of the present application, the movement direction of the terminal device indicates that the movement direction of the terminal device in the area provided by the first device or the network device is considered in paging. Based on the movement direction, the time domain in which the terminal device can communicate directly with the network device can be determined, and the time domain in which the terminal device needs to communicate with the network device through the first device can be determined. Therefore, the network device dynamically allocates different spatial information sets based on the spatial information set pattern, so that the terminal device can monitor the paging message at the appropriate time.

[0464] It should be noted that due to the high mobility of the terminal device, it is necessary to know the movement trajectory of the terminal device. Based on the movement trajectory, the time domain in which the terminal device can communicate directly with the network device and the time domain in which the terminal device communicates with the network device through the first device are determined. Therefore, the network device dynamically allocates different spatial information sets based on the spatial information set pattern, so that the terminal device can monitor the paging message at the appropriate time.

[0465] It can be understood that when the spatial information set is configured according to the spatial information set pattern, due to mobility, the terminal device corresponds to different spatial information sets at different times. For example, the UE position is located in the first area, the SSB set pattern is the third SSB set, the UE position is located in the second area, and the SSB set pattern is the first SSB set or the second SSB set. The UE position is calculated by the UE through a downlink positioning method and reported to the network device, or is calculated by the network device through an uplink positioning method. Therefore, it is necessary to consider the impact of the mobility of the terminal device on the terminal device's monitoring of the paging message, so that the terminal device can receive the paging message at the appropriate time.

[0466] In some embodiments, if the paging configuration information includes the first indication information and the fourth indication information, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0467] In an embodiment of the present application, the RRC release message or the specific signaling of the terminal device is a specific message configured by the network device for the terminal device, and the terminal device monitors the paging PDCCH based on the first indication information and the fourth indication information in the paging configuration information carried by the RRC release message or the specific signaling of the terminal device.

[0468] In some embodiments, before the terminal device receives the paging configuration information sent by the network device in step 610, the terminal device reports first information to the network device, wherein the paging configuration information is determined based on the first information;

[0469] The first information includes one or more of the following:

[0470] Information related to the mobility of terminal devices;

[0471] The measurement result of the service cell where the terminal device is located is obtained based on the measurement configuration information sent by the network device.

[0472] In the embodiment of the present application, the information related to the mobility of the terminal device includes one or more of the following:

[0473] The location of the terminal equipment;

[0474] The speed of the terminal device;

[0475] Movement patterns of terminal equipment;

[0476] Movement direction of the terminal device;

[0477] The timestamp corresponding to the terminal device's location.

[0478] In an embodiment of the present application, the measurement result is a result obtained by the terminal device measuring the service cell where the terminal device is located based on the measurement configuration information sent by the network device. The measurement result may include one or more of the following measurement parameters: channel measurement result, reference signal received power, reference signal received quality, signal-to-noise ratio, signal-to-interference-and-noise ratio, and other parameters. The embodiment of the present application does not limit this.

[0479] In an embodiment of the present application, mobility-related information such as the location of the terminal device, the speed of the terminal device, the movement pattern of the terminal device, the movement direction of the terminal device, and the timestamp corresponding to the location of the terminal device can provide parameters for configuring paging configuration information for the network device. For example, the network device determines whether the terminal device is located in the area provided by the first device based on the location of the terminal device. If the terminal device is located in the service area provided by the first device, the paging configuration information configured by the network device for the terminal device indicates the second spatial information set, so that the terminal device monitors the paging message at an appropriate time according to the paging configuration information.

[0480] In some embodiments, the network device receives capability information reported by the first device, wherein the capability information is a set of spatial information that the first device can support, and the configuration of the first timer and the configuration of the spatial information set pattern are determined based on the capability information.

[0481] In the embodiment of the present application, the second spatial information set may be a set of spatial parameters or a set of spatial information supported by the first device, wherein the set of spatial parameters or the set of spatial information may be a beam set.

[0482] In the embodiment of the present application, the direction of the spatial information supported by the first device may be fixed or semi-static.

[0483] It is understood that the fixed direction in which the first device forwards spatial information may mean that the amplitude and phase of the first device do not change, that is, the first device directly forwards the received spatial information according to the fixed amplitude and phase of its own unit. It should be noted that the capability information reported by the first device includes the set of spatial information that the first device can support based on the current fixed amplitude and phase of its own unit, that is, the second set of spatial information corresponding to the first device is reported.

[0484] It is understood that the semi-static direction in which the first device forwards spatial information may refer to changes in the amplitude and phase of the first device, i.e., the first device can adjust the amplitude and phase of its own unit, and the first device adjusts the spatial information it can forward according to the adjusted amplitude and phase. It should be noted that the capability information reported by the first device includes the set of spatial information that the first device can support based on the current fixed amplitude and phase of its own unit, as well as the changing pattern of the amplitude and phase of its own unit adjusted by the first device, i.e., the changing pattern of the second set of spatial information corresponding to the first device.

[0485] In some embodiments, the capability information may include one or more of the following:

[0486] a phase of each RIS unit in the first device;

[0487] a beamset of reflected or refracted signals from the first device;

[0488] a beamforming pattern of the reflected or refracted signal of the first device;

[0489] The polarization of the reflected or refracted signal.

[0490] It should be noted that the beam set of the reflected signal or the refracted signal of the first device may include different forwarding beam directions (reflection, refraction, etc.) corresponding to different working modes, as well as the number of beams.

[0491] In addition, the beamforming pattern of the reflected signal or refracted signal of the first device can be obtained by adjusting the on or off state of the diode associated with the RIS unit. That is, different on or off patterns of the diode correspond to different beamforming patterns of the RIS reflected signal or refracted signal, thereby corresponding to different RIS operating modes.

[0492] The polarization mode of the reflected signal or the refracted signal of the first device may include horizontal polarization or vertical polarization, wherein different operating modes correspond to different polarization modes.

[0493] In some embodiments, the capability information is sent via higher-layer signaling, such as RRC signaling or other higher-layer signaling used for interaction between the first device and the network device.

[0494] It can be seen that after the network device receives the capability information reported by the first device, the network device can accurately configure the first timer or spatial information set pattern according to the capability information reported by the first device, so that the terminal device determines whether the network device and the terminal device establish a communication link through the smart surface device based on the paging configuration information, or whether the network device and the terminal device directly establish a communication link. Furthermore, the terminal device uses the determined communication link to enable itself to monitor the paging at the appropriate time, thereby improving the quality of communication transmission while ensuring the accuracy of paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0495] FIG11 shows a paging method provided by an embodiment of the present application, which is applied to a first device. The method may include:

[0496] Step 710: When the first device reflects or refracts a signal transmitted between the network device and the terminal device, the first device sends a second spatial information set to the terminal device, where the second spatial information set is used by the terminal device to determine a paging resource in combination with the paging configuration information sent by the received network device; the paging resource is the paging resource corresponding to the first spatial information set, the second spatial information set, or the third spatial information set; the first spatial information set is all or part of the union of the second spatial information set and the third spatial information set; the third spatial information set is the spatial information set broadcast by the network device; and the second spatial information set is the spatial information set of the first device.

[0513] In the case where the first indication information indicates the second spatial information set, if the second indication information is the first value or the fourth value, the paging resource is the second paging resource; if the second indication information is the third value, the paging resource is the first paging resource.

[0514] In some embodiments, when the first indication information indicates the first spatial information set or the second spatial information set, if the second indication information is the second value or the fifth value, the paging resource is the third paging resource.

[0515] In some embodiments, when the paging configuration information includes the second indication information, the first indication information is carried in the dedicated signaling of the serving cell where the terminal device is located, and the second indication information is carried in the radio resource control RRC release message or the dedicated signaling of the terminal device; or, the first indication information and the second indication information are carried in the RRC release message or the dedicated signaling of the terminal device;

[0516] In the case that the paging configuration information does not include the second indication information, the first indication information is carried in the RRC release message or the dedicated signaling of the terminal device.

[0517] In some embodiments, the paging configuration information further includes third indication information, and the third indication information is used to configure the first timer.

[0518] In some embodiments, when the first indication information indicates the first spatial information set, the paging resource is the first paging resource during the operation of the first timer; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0519] In some embodiments, when the first indication information indicates the second spatial information set, the paging resource is the second paging resource during the operation of the first timer; or, when the first timer is not running or times out, the paging resource is the third paging resource.

[0520] In some embodiments, the configuration of the first timer is associated with information related to mobility of the terminal device.

[0521] In some embodiments, the paging configuration information further includes fourth indication information, and the fourth indication information is used to configure the spatial information set pattern.

[0522] In some embodiments, the spatial information set pattern is associated with one or more of the following:

[0530] In some embodiments, the paging configuration information is carried in an RRC release message or dedicated signaling of the terminal device.

[0531] In some embodiments, when the first spatial information set is all of the union of the second spatial information set and the third spatial information set, the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the second spatial information set, and / or the amount of spatial information in the first spatial information set is greater than the amount of spatial information in the third spatial information set.

[0532] In some embodiments, the amount of spatial information in the first spatial information set is equal to or less than the sum of the amount of spatial information in the second spatial information set and the amount of spatial information in the third spatial information set.

[0533] In some embodiments, it further includes:

[0534] The configuration of the first spatial information set is that the network device configures a first number of physical downlink control channel PDCCH monitoring opportunities for a PO corresponding to the terminal device based on the paging configuration information, and the first number is associated with the number of actually transmitted spatial information contained in the first spatial information set;

[0536] In some embodiments, the first paging resource, the second paging resource, and the third paging resource satisfy at least one of the following:

[0537] The first paging resource includes a second paging resource and a third paging resource;

[0538] The PDCCH monitoring opportunities corresponding to the second paging resource and the third paging resource do not overlap in the time domain;

[0539] The PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the time domain;

[0540] The PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the frequency domain;

[0541] The first paging resource, the second paging resource, and the third paging resource are scrambled and indicated using different paging radio network temporary identifiers P-RNTIs.

[0542] In some embodiments, the mobility-related information of the terminal device includes one or more of the following:

[0544] The speed of the terminal device;

[0548] In some embodiments, it further includes:

[0549] The first device reports capability information to the network device, where the capability information is a set of spatial information supported by the first device, and the configuration of the first timer and the configuration of the spatial information set pattern are determined based on the capability information.

[0550] In some embodiments, the method further includes: when the link quality between the terminal device and the network device meets a preset quality condition, the terminal device determines a paging resource based on the paging configuration information.

[0551] It should be noted that, for the description of the same steps and contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0552] In an embodiment of the present application, referring to FIG12 , a paging method provided in the embodiment of the present application further includes the following steps:

[0553] Step 810: The first device reflects or refracts a signal transmitted between the network device and the terminal device.

[0554] Step 820: The network device broadcasts the third space information set.

[0555] Step 830: The network device sends paging configuration information to the terminal device.

[0556] The paging configuration information is used to indicate the first spatial information set or the second spatial information set.

[0557] The second spatial information set is a spatial information set supported by the first device or a spatial information set associated with the first device. The first device is used to forward a beam corresponding to a signal sent by the network device to the terminal device, or to forward a beam corresponding to a signal sent by the terminal device to the network device. Forwarding includes reflecting or refracting, thereby changing the transmission direction of the beam corresponding to the signal.

[0558] Step 840: The terminal device determines a paging resource based on the paging configuration information, where the paging resource is a paging resource corresponding to the first spatial information set, the second spatial information set, or the third spatial information set.

[0559] The first spatial information set is all or part of the union of the second spatial information set and the third spatial information set, and the first spatial information set, the second spatial information set and the third spatial information set are not completely the same.

[0560] It can be understood that in an embodiment of the present application, when the network device and the terminal device may communicate through the first device, the terminal device receives paging configuration information from the network device for indicating the first spatial information set or the second spatial information set, and determines the paging resource based on the paging configuration information. In this way, after determining the paging resource, the terminal device uses the paging resource to monitor the P-RNTI-scrambled PDCCH at the PDCCH monitoring opportunity corresponding to the spatial information in the indicated spatial information set, wherein the number of PDCCH monitoring opportunities included in the PO is associated with the number of spatial information in the indicated spatial information set. In this way, after introducing the smart surface device, the terminal device can determine that the network device and the terminal device establish a communication link through the smart surface device based on the paging configuration information sent by the network device for indicating the first spatial information set or the second spatial information set. Furthermore, the terminal device uses the communication link to enable itself to monitor the paging at the appropriate time, thereby improving the communication transmission quality while ensuring the accuracy of the paging, reducing the probability of paging false alarms, and reducing the energy consumption of the terminal device.

[0561] Based on the above embodiment, in step 840, the terminal device determines the paging resources according to the indication information included in the paging configuration information, which can be divided into the following four cases:

[0562] Case 1: the paging configuration information includes only the first indication information, and the terminal device determines the paging resource based on the first indication information included in the paging configuration information;

[0563] Case 2: the paging configuration information includes first indication information and second indication information, and the terminal device determines the paging resource based on the first indication information and the second indication information included in the paging configuration information;

[0564] Case 3: the paging configuration information includes first indication information and third indication information, and the terminal device determines the paging resource based on the first indication information and the third indication information included in the paging configuration information;

[0565] Case 4: the paging configuration information includes first indication information and fourth indication information, and the terminal device determines the paging resources based on the first indication information and the fourth indication information included in the paging configuration information.

[0566] Example 1

[0567] The paging configuration information only includes the first indication information, and the terminal device determines the paging resources based on the first indication information included in the paging configuration information.

[0568] In an embodiment of the present application, the first indication information may indicate a first SSB set (first spatial information set), the first indication information may also indicate a second SSB set (second spatial information set), and the first indication information may indicate a third SSB set (third spatial information set); of course, the first indication information may also be empty, that is, it does not indicate any spatial information set, or the paging configuration information may not include the first indication information.

[0569] In an embodiment of the present application, the first SSB set corresponds to the first paging resource, the second SSB set corresponds to the second paging resource, and the third SSB set corresponds to the third paging resource. The paging resource is the first paging resource, the second paging resource, or the third paging resource.

[0570] In a first possible implementation manner, when the terminal device (UE) communicates with the network device through the first device (RIS device), the first indication information indicates the first SSB set.

[0571] In an embodiment of the present application, the first SSB set includes the SSBs in the third SSB set, that is, the number of SSBs included in the first SSB set is greater than the number of SSBs included in the third SSB set. When the SSB set corresponding to a PO of the terminal device is the first SSB set, the number of paging monitoring opportunities PMO corresponding to a PO is the same as the number of SSBs included in the first SSB set, or the number of paging monitoring opportunities PMO corresponding to a PO is an integer multiple of the number of SSBs included in the first SSB set, and the integer is the number of PDCCH monitoring opportunities corresponding to each SSB; here, the third SSB set is the SSB set broadcast by the network device, such as the SSB set configured by the high-level parameter ssb-PositionsInBurst in SIB1.

[0572] In this embodiment of the present application, the first SSB set includes the SSBs in the third SSB set and the SSBs in the second SSB set.

[0573] When the SSBs in the second SSB set are different from the SSBs in the third SSB set, the number of SSBs in the first SSB set is equal to the sum of the number of SSBs in the third SSB set and the number of SSBs in the second SSB set.

[0574] When the SSBs in the second SSB set are the same as the SSBs in the third SSB set, the number of SSBs in the first SSB set is less than the sum of the number of SSBs in the third SSB set and the number of SSBs in the second SSB set.

[0575] In an embodiment of the present application, when a UE communicates with a network device through a RIS device, the first indication information configured by the network device indicates a first SSB set, so that the beam set (second spatial information set) for communication between the UE and the RIS is included in the first SSB set. The UE uses the first paging resource corresponding to the first SSB set to blindly detect an SSB in the first SSB set corresponding to a PO to repeatedly transmit a PDCCH scrambled by the P-RNTI, thereby determining a paging message. This solution enables the UE to monitor the paging message, but also increases the UE's blind detection.

[0576] In a second possible implementation manner, when the UE communicates with the network device through the RIS device, the first indication information indicates the second SSB set.

[0577] In an embodiment of the present application, the second SSB set is a beam set forwarded by RIS, and the second SSB set is different from the SSB included in the third SSB set. When the SSB set corresponding to a PO of the terminal device is the second SSB set, the number of paging monitoring opportunities PMO corresponding to a PO is the same as the number of SSBs included in the second SSB set, or the number of paging monitoring opportunities PMO corresponding to a PO is an integer multiple of the number of SSBs included in the second SSB set, and the integer is the number of PDCCH monitoring opportunities corresponding to each SSB.

[0578] In an embodiment of the present application, when a UE communicates with a network device via a RIS device, the first indication information configured by the network device indicates a second SSB set, so that the beam set for communication between the UE and the RIS is included in the second SSB set. The UE uses a second paging resource corresponding to the second SSB set to blindly detect an SSB in the second SSB set corresponding to a PO to repeatedly transmit a PDCCH scrambled by the P-RNTI, thereby determining a paging message. This solution enables the UE to detect the paging message without increasing the number of blind detections performed by the UE.

[0579] In a third possible implementation manner, the first indication information indicates the third SSB set, or the first indication information is empty, or the paging configuration information does not include the first indication information.

[0580] In an embodiment of the present application, when the SSB set corresponding to a PO of the terminal device is the third SSB set, the number of paging monitoring opportunities PMO corresponding to a PO is the same as the number of SSBs included in the third SSB set, or, the number of paging monitoring opportunities PMO corresponding to a PO is an integer multiple of the number of SSBs included in the third SSB set, and the integer is the number of PDCCH monitoring opportunities corresponding to each SSB.

[0581] In an embodiment of the present application, the paging configuration information includes the third SSB set indicated by the first indication information, or the paging configuration information does not configure information related to the SSB set, then the third SSB set is used by default, and the third SSB set is the SSB included in the parameter ssb-PositionsInBurst in SIB1. At this time, it can be considered that the UE communicates directly with the network device without the need for RIS forwarding. Then, the UE uses the third paging resource corresponding to the third SSB set to monitor the SSB in the third SSB set corresponding to a PO to repeatedly send the P-RNTI-scrambled PDCCH to determine the paging message.

[0582] In the embodiment of the present application, the configuration of the first SSB set and the second SSB set through paging configuration information can be implemented as follows:

[0583] Method 1: Configure the first SSB set through paging configuration information. When a UE communicating with a network device through RIS monitors a paging message, the number of PDCCH monitoring opportunities corresponding to one PO is an integer multiple of the number of SSBs in the first SSB set, where the integer is the number of PDCCH monitoring opportunities corresponding to each SSB.

[0584] Method 2: Configure the second SSB set through paging configuration information. The number of PDCCH monitoring opportunities corresponding to one PO is an integer multiple of the sum of the SSB set broadcast by the network device and the number of SSBs in the second SSB set. This integer is the number of PDCCH monitoring opportunities corresponding to each SSB.

[0585] Method 3: Configure the second SSB set through paging configuration information. When a UE communicating with a network device through RIS monitors a paging message, the number of PDCCH monitoring opportunities corresponding to one PO is an integer multiple of the number of SSBs in the second SSB set, where the integer is the number of PDCCH monitoring opportunities corresponding to each SSB.

[0586] In the embodiment of the present application, the paging configuration information is included in UE-specific higher-layer signaling, such as an RRC Release message. For different UEs, the corresponding SSB sets may be different, so it should be placed in UE-specific signaling.

[0587] In the embodiment of the present application, the first paging resource, the second paging resource, and the third paging resource have at least one of the following characteristics:

[0588] The first paging resource includes a second paging resource and a third paging resource;

[0589] The PDCCH monitoring opportunities corresponding to the second paging resource and the third paging resource do not overlap in the time domain;

[0590] Differentiating by time domain resources, that is, the PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the time domain;

[0591] Differentiating by frequency domain resources, that is, the PDCCH monitoring opportunities corresponding to the first paging resource, the second paging resource, and the third paging resource do not overlap in the frequency domain;

[0592] The P-RNTI is used for differentiation, that is, the first paging resource, the second paging resource and the third paging resource are scrambled and indicated using different P-RNTIs.

[0593] Example 2

[0594] The paging configuration information includes first indication information and second indication information. The terminal device determines the paging resources based on the first indication information and the second indication information included in the paging configuration information.

[0595] In an embodiment of the present application, the second indication information may be a status value corresponding to a different number of bits, and the second indication information may also be used to indicate whether the SSB set indicated by the first indication information is applied. It should be noted that if the second indication information may also be used to indicate whether the SSB set indicated by the first indication information is applied, the data type of the second indication information may be an enumeration type or a Boolean type.

[0596] In a first implementation, the second indication information is a state value corresponding to different numbers of bits; for example, when the second indication information is 1 bit, state 0 (first value) indicates the first spatial information set or the second spatial information set, and state 1 (second value) indicates the third spatial information set. When the second indication information is 2 bits, state 00 (first value) indicates the first spatial information set, state 01 (second value) indicates the second spatial information set, and state 10 (third value) indicates the third spatial information set.

[0597] For the second indication information being 1 bit, for example, when the first indication information indicates the first SSB set and the second indication information is in state 0, the terminal device determines the paging resource as the first paging resource corresponding to the first spatial information set jointly indicated by the first indication information and the second indication information; when the first indication information indicates the first SSB set and the second indication information is in state 1, the terminal device determines the paging resource as the third paging resource corresponding to the third spatial information set indicated by the second indication information.

[0598] In another example, when the first indication information indicates the second SSB set and the second indication information is in state 0, the terminal device determines the paging resource as the second paging resource corresponding to the second spatial information set jointly indicated by the first indication information and the second indication information; when the first indication information indicates the second SSB set and the second indication information is in state 1, the terminal device determines the paging resource as the third paging resource corresponding to the third spatial information set indicated by the second indication information.

[0599] For the second indication information being 2 bits, for example, when the first indication information indicates the second SSB set and the second indication information is in state 00, the terminal device determines the paging resource as the first paging resource corresponding to the first spatial information set indicated by the second indication information; when the first indication information indicates the second SSB set and the second indication information is in state 01, the terminal device determines the paging resource as the second paging resource corresponding to the second spatial information set indicated by the first indication information and the second indication information; when the first indication information indicates the second SSB set and the second indication information is in state 10, the terminal device determines the paging resource as the third paging resource corresponding to the third spatial information set indicated by the second indication information.

[0600] In a second possible implementation, the second indication information is used to indicate whether the SSB set indicated by the first indication information is applied.

[0601] Exemplarily, when the first indication information indicates the first SSB set and the second indication information indicates that the SSB set indicated by the first indication information is applied, the terminal device determines the paging resource as the first paging resource corresponding to the first spatial information set; when the first indication information indicates the first SSB set and the second indication information indicates that the SSB set indicated by the first indication information is not applied, the terminal device determines the paging resource as the third paging resource corresponding to the third spatial information set.

[0602] In another example, when the first indication information indicates the second SSB set and the second indication information indicates that the SSB set indicated by the first indication information is applied, the terminal device determines the paging resource as the second paging resource corresponding to the second spatial information set; when the first indication information indicates the second SSB set and the second indication information indicates that the SSB set indicated by the first indication information is not applied, the terminal device determines the paging resource as the third paging resource corresponding to the third spatial information set.

[0603] In the embodiment of the present application, the first indication information and the second indication information may be carried in the same signaling or in different signalings, including the following two methods:

[0604] Method 1: The first indication information is carried in the dedicated signaling of the serving cell where the terminal device is located, and the second indication information is carried in the UE-dedicated signaling. For example, the first indication information is carried in SIB1, the high-level parameters ServingCellConfigCommon, PDCCH-configcommon, downlinkConfigCommon, and the second indication information is carried in the RRC release signaling, BWP-DownlinkDedicated.

[0605] The example structure is as follows:

[0606] Mode 2: Both the first indication information and the second indication information are carried in UE-specific signaling. For example, both the first indication information and the second indication information are carried in RRC release signaling.

[0607] It is understandable that due to the mobility of the UE, the communication performance of the UE communicating with the network device through the RIS device in the area covered by the RIS device is better, while in other areas, the communication performance of directly connecting with the network device is better. The first indication information is used to control the way in which the UE monitors the paging message, so that the UE can monitor the paging message at the appropriate time.

[0608] Example 3

[0609] The paging configuration information includes first indication information and third indication information. The terminal device determines the paging resources based on the first indication information and the third indication information included in the paging configuration information.

[0610] In the embodiment of the present application, the third indication information may be the first timer.

[0611] In one implementable manner, if the first timer is started within a time range (operating period) and the first indication information indicates the first SSB set, the terminal device determines that the paging resource is the first paging resource, and the UE monitors the paging message on the first paging resource. If the first timer is not running or times out, the terminal device determines that the paging resource is the third paging resource, and the UE monitors the paging message on the third paging resource corresponding to the third SSB set.

[0612] In another possible implementation, within the first timer start time range (operation period), and the first indication information indicates the second SSB set, the terminal device determines that the paging resource is the second paging resource, and the UE monitors the paging message on the second paging resource. If the first timer is not running or times out, the terminal device determines that the paging resource is the third paging resource, and the UE monitors the paging message on the third paging resource.

[0613] It should be noted that, since the mobility of the UE has a certain impact on the UE monitoring of the paging message, the configuration of the first timer can be associated with the mobility of the UE, for example, factors such as the location of the UE, the speed of the UE, the movement pattern of the UE, the direction of movement of the UE, and the timestamp corresponding to the location of the UE.

[0614] It can be understood that due to mobility, the terminal device will receive a paging message in the paging resources corresponding to the third spatial information set in a certain area, and receive a paging message in the paging resources corresponding to the first spatial information set or the second spatial information set in another area. Exemplarily, the terminal device is located in the first area, and the terminal device receives a paging message in the paging resources corresponding to the third SSB set. The terminal device is located in the second area, and the terminal device receives a paging message in the paging resources corresponding to the first SSB set or the second SSB set. The time taken by the terminal device to move from the first area to the second area can be the time range of the first timer.

[0615] It can be understood that the network device configures the SSB set according to the first timer to take into account the impact of UE mobility on the UE's monitoring of paging messages, so that the UE can receive the paging message at an appropriate time.

[0616] Example 4

[0617] The paging configuration information includes first indication information and fourth indication information. The terminal device determines the paging resources based on the first indication information and the fourth indication information included in the paging configuration information.

[0618] In an embodiment of the present application, the fourth indication information may be an SSB set pattern (spatial information set pattern), the SSB set pattern may be associated with the PF of the UE or the PO within the PF, and the SSB set pattern may also be associated with the time domain subframe configuration of the UE.

[0619] In a first implementation manner, the SSB set pattern is associated with the PF of the UE or the PO within the PF.

[0620] Here, different SSB sets are applied to different PFs of the UE. For example, if the number of PFs monitored by the UE in a DRX cycle is 2, the SSB set corresponding to the first PF is the second SSB set, and the SSB set corresponding to the second PF is the third SSB set. In other words, the SSB set corresponding to each PF is the same.

[0621] Here, different POs within a PF of the UE apply different SSB sets. For example, if the UE monitors paging messages at two POs within a PF, the SSB set corresponding to the first PO is the second SSB set, and the SSB set corresponding to the second PO is the third SSB set.

[0622] In the second implementation method, the SSB set pattern is associated with the time domain subframe configuration of the UE. For example, a system frame includes 10 subframes, and the SSB set corresponding to each one or more subframes is the second SSB set, and the SSB set corresponding to another part of the subframes is the third SSB set; or, the SSB set corresponding to a part of the subframes is the first SSB set, the SSB set corresponding to a part of the subframes is the second SSB set, and the SSB set corresponding to another part of the subframes is the third SSB set. This is because the beam set supported by the first device may be associated with the time domain subframe configuration, and the beam sets supported by different one or more subframes may be different. Adjusting the SSB set in a semi-static manner can reduce signaling overhead.

[0623] It should be noted that, since the mobility of the UE has a certain impact on the UE's monitoring of paging messages, the configuration of the SSB set pattern can be associated with the mobility of the UE. For example, factors such as the position of the UE, the speed of the UE, the movement pattern of the UE, the movement direction of the UE, and the timestamp corresponding to the UE position. Exemplarily, when the UE is in position 1, it can communicate directly with the network device, that is, there is no need for the first device to forward the signal, then the paging resource may be the paging resource corresponding to the third spatial information set; when the UE moves to position 2, because there is an obstruction between it and the network device, it communicates with the network device through the first device, then the paging resource may...
