[0090] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0091] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0092] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0093] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0094] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0095] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0096] In some embodiments, during the communication process with the terminal, the network device may send first information to the terminal, such as a system information block (SIB), a physical downlink channel, a reference signal, etc.

[0097] During this process, the network device may stop sending the first information to the terminal for some reasons. For example, for the first information that is stopped from being sent, the terminal requests the network device to send the first information, and the network device sends the first information. In this case, the status of the first information can be called on demand.

[0098] Alternatively, the network device stops sending the first information to the terminal based on the cell communication situation. In this case, the state of the first information can be called on demand.

[0099] It should be noted that the meaning of the first information being in an on-demand state is not limited to the network device sending the first information only when the terminal requests the first information.

[0100] In some embodiments, from the perspective of the network device, the first information being in an on-demand state may mean that although the network device has sent the configuration of the first information to the terminal, the network device stops sending the first information to the terminal based on the configuration, and the network device continues to send the first information to the terminal based on the configuration after receiving the request information from the terminal requesting the network device to send the first information; the first information being in a non-on-demand state may mean that the network device has sent the configuration of the first information to the terminal, and sends the first information to the terminal based on the configuration.

[0101] In some embodiments, from the perspective of the terminal, the first information being in an on-demand state may mean that although the network device has sent the configuration of the first information to the terminal, the terminal has not received the first information from the network device based on the configuration. When the terminal needs to obtain the first information, the terminal sends a request message to the network device requesting the network device to send the first information; the first information being in a non-on-demand state may mean that the network device has sent the configuration of the first information to the terminal, and the terminal can receive the first information based on the configuration.

[0102] In some embodiments, based on the difference of the first information, the network device may send the first information to the terminal in different ways. For example, the first information may be sent through broadcast, multicast, groupcast, unicast, etc., and this disclosure does not limit this.

[0103] It can be seen that since the first information can be in both on-demand and non-on-demand states, some technical problems may arise when the terminal does not know the status of the first information. For example, after the first information enters the on-demand state, the terminal does not know that the first information has entered the on-demand state, and still continues to try to receive the first information based on the configuration of the first information. However, since the first information is in the on-demand state, the network device stops sending the first information based on the configuration, and the terminal cannot receive the first information, which will cause unnecessary overhead to the terminal.

[0104] FIG2 is an interactive schematic diagram showing a method for sending information according to an embodiment of the present disclosure.

[0105] As shown in FIG2 , the information receiving method includes the following steps:

[0106] Step S201: The network device sends instruction information to the terminal.

[0107] In some embodiments, the indication information is used by the terminal to determine a status of the first information, wherein the status includes at least one of the following: on-demand, not on-demand.

[0108] In some embodiments, the terminal receives indication information sent by the network device.

[0109] Step S201: The terminal determines a status of the first information according to indication information, wherein the status includes at least one of the following: on-demand and non-on-demand.

[0110] According to an embodiment of the present disclosure, the terminal can determine the status of the first information based on the indication information sent by the network device, for example, it can determine whether the first information is in an on-demand state or a non-on-demand state. This is helpful to avoid unnecessary operations of the terminal and unnecessary overhead.

[0111] For example, when the state of the first information changes from non-on-demand to on-demand, the network device may send indication information to the terminal, so that the terminal determines that the state of the first information is on-demand.

[0112] When the terminal determines that the first information is in the on-demand state, the terminal may stop receiving the first information based on the configuration of the first information, and send a request message to the network device to request the network device to send the first information.

[0113] After receiving the request information, the network device sends confirmation information (ACK) to the terminal when it determines that the first information can be sent. Based on the confirmation information, the terminal can determine that the network device will continue to send the first information, and thus can continue to receive the first information based on the configuration.

[0114] For example, when the state of the first information changes from on-demand to non-on-demand, the network device may send indication information to the terminal so that the terminal determines that the state of the first information is non-on-demand. When the terminal determines that the first information is in the non-on-demand state, it may continue to receive the first information based on the configuration of the first information.

[0115] In some embodiments, in addition to determining that the status of the first information is changed from non-on-demand to on-demand according to the first indication information, the terminal may also determine that the status of the first information is changed from non-on-demand to on-demand through other methods.

[0116] For example, the terminal determines, based on a predefined method, that the status of the first information is changed from non-on-demand to on-demand.

[0117] When the terminal does not receive the first information for a first period of time while receiving the first information based on the configuration of the first information, it can be determined that the status of the first information has changed from non-on-demand to on-demand, where the first period of time can be configured by the network device to the terminal, or can be agreed upon by the protocol.

[0118] In some embodiments, the starting position of the first duration may be any reception timing of the first information at which the first information is not received, or the reception timing before the reception timing, or q time domain units after the reception timing at which the first information is not received. The length of the first duration may be p time domain units. Here, p and q may be configured by the network device or determined based on a protocol agreement.

[0119] The time domain unit includes at least one of the following: a frame, a subframe, a time slot, a symbol, an SSB cycle, a blind detection cycle of DCI, and a paging cycle.

[0120] In some embodiments, the first information includes at least one of the following: a synchronization broadcast signal block (SS (Synchronization Signal) and PBCH (Physical downlink Broadcast Channel) Block, SSB); a system information block SIB1.

[0121] It should be noted that the first information is not limited to the above-mentioned SSB and SIB1, but may also include other information, such as Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), and other newly defined signals, such as signals composed of primary synchronization signals and secondary synchronization signals, discovery reference signals (DRS), etc.

[0122] In some embodiments, when the first information includes SIB1, when the terminal has not received SIB1 in the current cell, SIB1 can be received according to the configuration of SIB1; and when the terminal has already received SIB1 in the current cell, SIB1 can be received according to the configuration of SIB1 only when it is determined that SIB1 needs to be updated, and when SIB1 does not need to be updated, the reception of SIB1 can be suspended.

[0123] In some embodiments, when the first information includes at least one of SSB and SIB1, the first information is relatively important information. Under normal circumstances, the first information will not enter the on-demand state. However, the network device can still make the first information enter the on-demand state for certain needs. For example, the network device needs to enter the Network Energy Saving (NES) mode. Then, for energy saving considerations, the sending of the first information can be stopped, so that the first information enters the on-demand state.

[0124] Therefore, in some embodiments, the request information sent by the terminal to the network device to request the network device to send the first information may also be referred to as a wake-up signal (WUS), which may be used to wake up the network device from the NES mode. After the network device is woken up from the NES mode, it may continue to send the first information. Of course, in some embodiments, the network device may also send the first information based on the request information when in the NES mode.

[0125] In some embodiments, when the first information is in the on-demand state, the terminal may request information from the network to request the first information to enter the non-on-demand state, wherein the terminal may send the first information to the network device on the resource used to send the request information.

[0126] In some embodiments, when the first information includes SIB1, if the terminal has not received SIB1 in the current cell, the terminal cannot obtain the frequency domain information corresponding to the initial uplink bandwidth part (BandWidth Part, BWP), and the terminal will not be able to be configured with resources for requesting information by the network device in a conventional manner.

[0127] In this case, the resource for the requested information may be determined based on a predefined method, for example, the pattern corresponding to the resource for the requested information is agreed upon by the protocol. For example, the protocol agrees on multiple patterns corresponding to the resource for the requested information. Although the terminal may not have received SIB1, it may have received the Master Information Block (MIB). The terminal may determine one of the multiple patterns as the resource for the requested information based on information in the MIB (e.g., the PDCCH in the MIB used to schedule SIB1, i.e., pdcch-ConfigSIB1).

[0128] In some embodiments, the indication information includes at least one of the following: Radio Resource Control (RRC) signaling; Downlink Control Information (DCI).

[0129] Of course, the type of indication information is not limited to the above-mentioned RRC signaling and DCI, and may also be other types, such as a Media Access Control Control Element (MAC CE), and the present disclosure is not limited to this. The following embodiments mainly illustrate the technical solutions of the present disclosure in the case where the indication information is RRC signaling and the indication information is DCI.

[0130] In some embodiments, the first information includes an SSB, and the RRC signaling includes an information unit (Information, Element, IE) for indicating an SSB index.

[0131] In the case where the indication information is RRC signaling, when the first information includes SSB, the RRC signaling may include an IE for indicating the SSB index. For example, the IE may be ssb-PositionsInBurst, and ssb-PositionsInBurst is used to indicate the index of the SSB actually sent in an SSB burst.

[0132] In some embodiments, all bits of the information unit are 0, and the information unit is used by the terminal to determine that the status of the SSB is on demand, and / or at least one bit in the information unit is not 0, and the information unit is used by the terminal to determine that the status of the SSB is not on demand.

[0133] For example, the bits in the information unit can be used to indicate the index of the SSB actually sent in an SSB burst. When all the bits of the information unit are 0, the value of the information unit is also 0, indicating that no SSB is actually sent in the SSB burst. The terminal can determine that the status of the SSB is on demand; when at least one bit in the information unit is not 0, the value of the information unit is also not 0, indicating that the SSB with the index corresponding to the value of the information unit in the SSB burst will be sent, and the terminal can determine that the status of the SSB is not on demand.

[0134] In some embodiments, for the ssb-PositionsInBurst configured by ServingCellConfigCommonSIB, ssb-PositionsInBurst may include at least one of the two IEs, inOneGroup and groupPresence. Then, when all bits of at least one of the two IEs are 0, the terminal may determine that the status of the SSB is on-demand; when at least one bit of at least one of the two IEs is not 0, the terminal may determine that the status of the SSB is not on-demand.

[0135] In some embodiments, for ssb-PositionsInBurst in ServingCellConfigCommon, ssb-PositionsInBurst may include at least one of the three IEs: shortBitmap, mediumBitmap, and longBitmap. Then, when all bits of at least one IE among these three IEs are 0, the terminal may determine that the status of the SSB is on-demand; when at least one bit of at least one IE among these three IEs is not 0, the terminal may determine that the status of the SSB is not on-demand.

[0136] In some embodiments, the indication information may include signaling for triggering activation / deactivation of a secondary cell (SCell), for example:

[0137] MAC CE used to trigger SCell activation / deactivation, e.g., MAC CE Enhanced Scell ​​Activation / Deactivation.

[0138] Exemplarily, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in the active state, the terminal determines that the state of the first information has changed. At this time, the terminal determines that the first information is non-on-demand. For example, for SIB1, it can be determined that the network device broadcasts SIB1 based on the configuration information of SIB1.

[0139] For example, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in a deactive state, the terminal determines that the state of the first information has changed. At this time, the terminal determines that the first information is non-on-demand. For example, for SIB1, it can be determined that the network device stops broadcasting SIB1 based on the configuration information of SIB1. The network device will continue to broadcast SIB1 based on the configuration information of SIB1 only after receiving the request information sent by the terminal.

[0140] In some embodiments, the first information includes SIB1, the RRC signaling does not include a first search space on a first bandwidth part, and the RRC signaling is used by the terminal to determine that the status of the SIB1 is on-demand, and / or, the RRC signaling includes the first search space on the first bandwidth part, and the RRC signaling is used by the terminal to determine that the status of the SIB1 is not on-demand.

[0141] In some embodiments, the first search space may include a search space for downlink control information (eg, DCI 1_0) for scheduling SIB1, for example, searchspaceSIB1.

[0142] When the terminal determines that the network device has not configured the first search space on the first BWP through RRC, the terminal can determine that the network device has not configured to send SIB1, and the network device stops sending SIB1 based on the configuration. As a result, the terminal cannot receive SIB1 based on the configuration, and the terminal can determine that the status of SIB1 is on-demand.

[0143] When the terminal determines that the network device has not configured the first search space on the first BWP through RRC, the terminal can determine that the network device has sent the SIB1 configuration, and the network device will send SIB1 based on the configuration. Therefore, the terminal can receive SIB1 based on the configuration, and the terminal can determine that the status of SIB1 is not on demand.

[0144] In some embodiments, the first bandwidth portion does not include at least one of the following:

[0145] The initial bandwidth part (initial BWP) where the control resource set CORESET#0 is located;

[0146] The first parameter is the same as the initial bandwidth part, and the frequency domain range includes the active bandwidth part (active BWP) of CORESET#0;

[0147] The activation bandwidth portion of the initial bandwidth portion.

[0148] In some embodiments, the first reference includes at least one of the following: Sub-Carrier Spacing (SCS) and Cyclic Prefix (CP).

[0149] In some embodiments, for the following cases: the first BWP is the initial BWP of CORESET#0, or the first BWP is the same as the first parameter of the initial bandwidth part, and the frequency domain range includes the active BWP of CORESET#0, or the first BWP includes the activated bandwidth part in the initial bandwidth part, even if the network device does not configure the first search space on the first BWP through RRC, the terminal can determine the configuration of SIB1 through other means (e.g., based on pdcch-ConfigSIB1 in the MIB). Therefore, for these cases, even if the network device does not configure the first search space on the first BWP through RRC, when the terminal determines the configuration of SIB1 through other means and receives the corresponding SIB based on the configuration, it can also determine that the status of the SIB is not on demand.

[0150] In some embodiments, when the first information includes RRC signaling, the RRC signaling can be traditional RRC signaling or newly defined RRC signaling, wherein the newly defined RRC signaling is transparent to the legacy terminal, that is, the legacy terminal does not parse the newly defined RRC signaling. Accordingly, it is helpful to avoid the newly defined RRC signaling affecting the behavior of the legacy terminal when the terminal determines whether the first information is in an on-demand or non-on-demand state.

[0151] In some embodiments, the DCI includes at least one of the following: traditional DCI; newly defined DCI; traditional DCI scrambled by a newly defined Radio Network Temporary Identity (RNTI).

[0152] For example, the newly defined DCI may be a DCI of a new format, such as DCI 2_10;

[0153] For example, the traditional DCI scrambled by the newly defined RNTI may be DCI 1_0, DCI 2_9, etc., and the newly defined RNTI may be, for example, a demand-RNTI, an on-demand RNTI, etc.

[0154] In some embodiments, the DCI may be configured with a common search space (CSS) or based on a terminal specific search space (USS), which is not limited in the present disclosure.

[0155] In some embodiments, the traditional DCI includes at least one of the following:

[0156] The first DCI scrambled by the system information radio network temporary identifier SI-RNTI;

[0157] The second DCI scrambled by the paging radio network temporary identifier P-RNTI is used.

[0158] In some embodiments, the reserved bits in the DCI are used by the terminal to determine the status of the first information.

[0159] For example, the reserved bit in the DCI can indicate that the first information is in an on-demand state. For example, for SIB1, the terminal can determine that the network device stops broadcasting SIB1 based on the configuration information of SIB1 according to the reserved bit in the DCI. The terminal can choose to stop receiving SIB1 based on the configuration of SIB1 during the period when SIB1 is in the on-demand state. The network device will continue to broadcast SIB1 based on the configuration information of SIB1 only after receiving the request information sent by the terminal.

[0160] For example, the reserved bit in the DCI can indicate that the first information is in a non-on-demand state. For example, for SIB1, the terminal can determine that the network device broadcasts SIB1 based on the configuration information of SIB1 according to the reserved bit in the DCI. When the terminal has not received SIB1, or when it determines that SIB1 needs to be updated, it can receive SIB1 based on the configuration of SIB1.

[0161] For example, for the first DCI, there are reserved bits in the first DCI, and the number of reserved bits may vary based on different DCIs. For example, SI-RNTI-scrambled DCI 1_0 may have 17 reserved bits, and at least one of these reserved bits can be used to indicate that the first information of the terminal is in an on-demand state or a non-on-demand state.

[0162] In some embodiments, the short message indication (SMI) information field in the second DCI is used to indicate paging scheduling, and the reserved bits include bits in the short message indication information field; and / or, the short message indication information field in the second DCI is used to indicate short message scheduling, and the reserved bits include bits outside the short message indication information field.

[0163] For example, for the second DCI, the short message indicator information field in the second DCI has two indication functions, one is to indicate paging scheduling, and the other is to indicate short message scheduling.

[0164] When the short message indicator indicates paging scheduling, the role of the short message indicator is relatively weak, so the bits in the short message indicator can be used as reserved bits.

[0165] When the short message indicator indicates short message scheduling, the role of the short message indicator is relatively important. Therefore, the bits in the short message indicator cannot be used as reserved bits. Instead, bits in information fields other than the short message indicator can be used as reserved bits. In addition, short message scheduling mainly involves PDCCH-related content. Therefore, the bits in the relevant information fields related to the PDSCH in the second DCI, such as the frequency domain resource assignment (FDRA) information field, the time domain resource assignment (FDRA) information field, the virtual resource block to physical resource block mapping (VRB-to-PRB mapping) information field, the modulation and coding scheme (MCS) information field, the redundancy version (RV) information field, the transport block size (TB scaling) information field, etc., can be used as reserved bits.

[0166] For example, for the second DCI, the second DCI has three indication functions, one indicating paging scheduling, one indicating short message scheduling, and one indicating corresponding TRS function. The rules are similar to those in the above embodiment and will not be repeated here.

[0167] It should be noted that, in some embodiments, the indication information may not only indicate the status of the first information, but also indicate the content of the information, which is exemplified below through several embodiments.

[0168] In some embodiments, the indication information further includes information of at least one cell, and the indication information is used by the terminal to determine at least one of the following: a status of the first information in the at least one cell.

[0169] For example, the network device may further indicate information about at least one cell, such as a cell ID, through the indication information. Based on the cell indicated by the indication information and the status of the first information indicated by the indication information, the terminal may determine the status of the first information in the cell. This enables cross-cell (or cross-carrier) indication of the status of the first information, which improves the flexibility of the indication operation.

[0170] The at least one cell may include the cell where the terminal is currently located (for example, a cell for receiving DCI), and may also include a neighboring cell of the cell where the terminal is currently located, a primary cell, a secondary cell, etc. accessed by the terminal.

[0171] It should be noted that, in addition to indicating the information of at least one cell, the indication information can also indicate other effective granularity information, such as bandwidth part information, beam information, SSB index information, etc.

[0172] For example, the terminal can determine the BWP where the status of the first information indicated by the indication information is effective based on the bandwidth part information indicated by the indication information; for example, the terminal can determine the beam where the status of the first information indicated by the indication information is effective based on the beam information indicated by the indication information; for example, the terminal can determine the beam where the status of the first information indicated by the indication information is effective (for example, corresponding to the SSB index information) based on the SSB index information indicated by the indication information.

[0173] In some embodiments, the indication information is further used by the terminal to determine the effective time of the status, or the effective time is determined based on a predefined method.

[0174] In some embodiments, the indication information may also indicate the effective time of the state when indicating the first information state. Of course, the effective time is not limited to being determined based on the indication information, and may also be determined based on a predefined method.

[0175] For example, when the indication information indicates that the first information is in an on-demand state and the effective time is T1, if the terminal needs to obtain the first information within T1, it can send a request to the network device to request the network device to send the first information; and since the first information is in a non-on-demand state outside T1, for example, for SIB1, the network device will continue to broadcast SIB1, then the terminal can receive SIB according to the configuration information of SIB1 outside the first time range.

[0176] In some embodiments, the effective time may be determined based on one of the following: a start time, a duration.

[0177] At least one of the start time and the duration may be indicated by the indication information, and at least one of the start time and the duration may be determined based on a protocol agreement.

[0178] For example, when the start time is determined based on an agreement, the start time includes at least one of the following:

[0179] Indicates the time domain unit where the information is located;

[0180] Indicates the starting position of the next SSB period of the time domain unit where the information is located;

[0181] Indicates the starting position of the next Type 0 CSS period in the time domain unit where the information is located.

[0182] The time domain unit includes at least one of the following: a frame, a subframe, a time slot, a symbol, an SSB cycle, a blind detection cycle of DCI, and a paging cycle.

[0183] Where the duration is determined based on an agreement, the duration includes at least one of the following:

[0184] a first number of SSB periods, wherein the SSB period is configured by the network device or is predefined (e.g., predetermined to be 20 milliseconds);

[0185] A second number of Type 0 CSS periods, wherein the Type 0 CSS period is configured by the network device or is predefined (for example, predetermined to be 20 milliseconds).

[0186] The first quantity and the second quantity may be configured by the network device or determined based on a protocol agreement, and the present disclosure does not limit this.

[0187] For example, when the first information is the first DCI, if the effective time is determined based on a protocol agreement, the effective time includes at least one of the following:

[0188] The first SSB period after the time domain unit where the first DCI is located;

[0189] A blind detection period of the first DCI after the time domain unit where the first DCI is located;

[0190] The maximum value of the above two effective times.

[0191] For example, when the first information is the second DCI, if the effective time is determined based on a protocol agreement, the effective time includes at least one of the following:

[0192] The first SSB period after the time domain unit where the second DCI is located;

[0193] The blind detection period of the first second DCI after the time domain unit where the second DCI is located;

[0194] The first paging cycle after the time domain unit where the second DCI is located;

[0195] The first paging frame (PF) after the time domain unit where the second DCI is located;

[0196] The first paging occasion (PO) after the time domain unit where the second DCI is located;

[0197] The maximum value among the above five validity periods.

[0198] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0199] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0200] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0201] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0232] In some embodiments, the short message indication information field in the second DCI is used to indicate paging scheduling, and the reserved bits include bits in the short message indication information field; and / or, the short message indication information field in the second DCI is used to indicate short message scheduling, and the reserved bits include bits outside the short message indication information field.

[0233] In some embodiments, the indication information further includes information of at least one cell, and the indication information is used by the terminal to determine at least one of the following: a status of the first information in the at least one cell.

[0234] In some embodiments, the indication information is further used by the terminal to determine the effective time of the status, or the effective time is determined based on a predefined method.

[0235] The technical solution of the present disclosure is exemplified below through several embodiments.

[0236] Example 1: A base station (eg, a network device including a base station) implements a status indication of first information based on an existing RRC signaling design. The first information may be, for example, an SIB, an SSB, or the like.

[0237] In Example 1.1, for SSB, the RRC signaling may include ssb-PositionsInBurst. For ssb-PositionsInBurst configured by ServingCellConfigCommonSIB, the corresponding signaling is as follows:

[0238] Exemplarily, if the bit indication values ​​in the inOneGroup IE and / or groupPresence IE are all 0, it indicates that the corresponding base station no longer sends the corresponding SSB. Conversely, if the bit indication values ​​in the inOneGroup IE and / or groupPresence IE are not all 0, it indicates that the corresponding base station continues to send the corresponding SSB.

[0239] From the perspective of the terminal, if the bit indication values ​​in the corresponding indication signaling inOneGroup IE and / or groupPresence IE received by the terminal are all 0, the terminal determines to stop receiving the SSB. Conversely, if the bit indication values ​​in the inOneGroup IE and / or groupPresence IE are not all 0, the terminal continues to receive the corresponding SSB.

[0240] Corresponding to the ssb-PositionsInBurst configured in ServingCellConfigCommon, the signaling is as follows:

[0241] Exemplarily, if the bit indication values ​​in the IE shortBitmap and / or mediumBitmap and / or longBitmap IE are all 0, it indicates that the corresponding base station no longer sends the corresponding SSB. Conversely, if the bit indication values ​​in the IE shortBitmap and / or mediumBitmap and / or longBitmap are not all 0, it indicates that the corresponding base station continues to send the corresponding SSB.

[0242] From the perspective of the terminal, if the bit indication values ​​in the corresponding indication signaling shortBitmap and / or mediumBitmap and / or longBitmap IE received by the terminal are all 0, the terminal determines to stop receiving the SSB. Conversely, if the bit indication values ​​in the shortBitmap and / or mediumBitmap and / or longBitmap IE are not all 0, the terminal continues to receive the corresponding SSB.

[0243] In Example 1.2, for SIB1, RRC signaling may be searchspaceSIB1 signaling. Except for the initial BWP where CORESET#0 is located, and / or an active BWP that meets the following conditions: the SCS and CP length corresponding to the initial DL BWP are the same, and the frequency domain range where the active DL BWP is located includes CORESET0, or an active BWP on the initial DL BWP, if the base station does not configure searchspaceSIB1 on the corresponding BWP, the base station abandons the corresponding SIB1 transmission. Conversely, if the base station reconfigures searchspaceSIB1 on the corresponding BWP through RRC signaling, the base station performs the corresponding SIB1 transmission.

[0244] From the terminal's perspective, if the terminal receives the searchspaceSIB1 configuration in the corresponding BWP, the terminal blindly detects the corresponding DCI based on the searchspace configuration. If the corresponding DCI is detected, the terminal receives the corresponding SIB1 based on the DCI scheduling.

[0245] In Example 1.3, the RRC signaling corresponding to Example 1.1 and Example 1.2 can be existing signaling. Alternatively, it can be newly defined RRC signaling in addition to existing signaling. The primary motivation for introducing the newly defined RRC signaling is that it is cell-level public signaling. If there are legacy users in the cell, the newly defined RRC signaling is transparent to the legacy users and does not affect the corresponding behavior of the legacy UE.

[0246] Example 1.4, in addition to the on-demond SSB / SIB1 status indication defined in the above embodiment, this embodiment mainly designs a mechanism to determine the effective time window of on-demond SSB / SIB1, that is, the time window in which the base station does not send SSB / SIB1, and / or the time window in which the base station sends SSB / SIB1, and the time window in which the terminal does not receive SSB / SIB1, and / or the time window in which the terminal receives SSB / SIB1.

[0247] The time window may be determined based on a signaling indication or a predefined manner. Exemplarily, the validity window is determined based on one or more of the following manners:

[0248] The starting position of the effective window is the time when the signaling is transmitted;

[0249] The validity window starts at the starting position of the next SSB cycle where the signaling is located;

[0250] The validity window starts at the start position of the next Type 0 CSS period where the signaling is located;

[0251] The validity window length is equal to N SSB periods, where the SSB period is based on signaling configuration or is a default period (e.g., 20 ms);

[0252] The effective window length is equal to the blind detection period corresponding to M Type 0 CSSs, and the blind detection period is based on signaling configuration or is a default period (for example, 20ms).

[0253] Based on the above formula in Example 1, a terminal supporting network energy saving receives an indication signaling, determines a corresponding on-demand signal state, and determines an effective window based on a predefined method or the indication signaling, and receives or does not receive corresponding first information (e.g., SSB, SIB1, etc.) within the effective window.

[0254] Embodiment 2: A base station (e.g., a network device including a base station) refarms existing DCI to implement on-demand SSB / SIB1 status indication. Correspondingly, a UE supporting the on-demand SSB / SIB1 feature can implement a status indication of first information based on the refarmed information field when receiving the corresponding DCI. The first information may be, for example, an SIB, SSB, etc.

[0255] Embodiment 2.1: Exemplarily, the base station indicates the status of the corresponding on-demand SSB / SIB1 using DCI 1_0 scrambled based on SI-RNTI. The DCI may include one or more of the following information fields.

[0256] Information field corresponding to the SSB transmission status: illustratively, no longer transmitting the corresponding SSB, or continuing to transmit the corresponding SSB;

[0257] Information field corresponding to the SIB1 transmission status: illustratively, no longer transmitting the corresponding SIB1, or continuing to transmit the corresponding SIB1;

[0258] The information field for the starting position (offset) of the validity window corresponding to the transmission state. Exemplarily, the terminal determines the starting position of the corresponding time window based on the time unit in which the DCI is received and the offset indication. The offset is based on the granularity of time units, such as frame, subframe, slot, symbol, SSB period, Type 0 CSS blind detection period, etc.

[0259] The information field of the time length of the corresponding transmission state; illustratively, the time length is granularized in time units, and the time units are based on the above definition and will not be repeated here.

[0260] The information field of the cell / BWP / SSB index / beam corresponding to the effective transmission state, exemplarily, the information field can be used for the cell, BWP, SSB index and beam, etc. to which the DCI indication information is applied.

[0261] Exemplarily, the information field or information may be carried based on the reserved bits of the SI-RNIT-scrambled DCI 1_0, exemplarily 17 bits of reserved bits.

[0262] Exemplarily, the corresponding effective time may also be determined based on a predefined method, and the effective time may be confirmed based on at least one of the following:

[0263] Cycle 1: the first SSB cycle after receiving the DCI;

[0264] Cycle 2: the blind detection cycle of the first SI-RNTI-scrambled DCI 1_0 after receiving the DCI;

[0265] The maximum value of period 1 and period 2.

[0266] Example 2.2: Exemplarily, the base station indicates the status of the first information based on the DCI 1_0 scrambled by the P-RNTI. The DCI may include one or more of the following information fields:

[0267] Information field corresponding to the SSB transmission status: illustratively, no longer transmitting the corresponding SSB, or continuing to transmit the corresponding SSB;

[0268] Information field corresponding to the SIB1 transmission status: illustratively, no longer transmitting the corresponding SIB1, or continuing to transmit the corresponding SIB1;

[0269] The information field of the starting position (offset) of the validity window corresponding to the transmission state. Exemplarily, the terminal determines the starting position of the corresponding time window based on the time unit in which the DCI is received and the offset indication. The offset is based on the granularity of the time unit, such as: frame, subframe, slot, symbol, SSB cycle, blind landing cycle corresponding to the DCI, paging cycle, etc.

[0270] The information field of the time length of the corresponding transmission state; illustratively, the time length is granularized in time units, and the time units are based on the above definition and will not be repeated here.

[0271] The information field of the cell / BWP / SSB index / beam corresponding to the effective transmission state, exemplarily, the information field can be used for the cell, BWP, SSB index and beam, etc. to which the DCI indication information is applied.

[0272] Exemplarily, the information field or information can be carried on the reserved bits of DCI 1_0 encrypted based on P-RNIT. Exemplarily, when the short Message Indicator in DCI1-0 is only used to indicate paging information scheduling, the reserved field is the short Message field; Exemplarily, when the short Message Indicator in DCI1_0 is only used to indicate short message information scheduling, the reserved field is one or more of the following: FDRA field, TDRA field, VRB-to-PRB mapping field, MCS field, RV field, TB scaling field.

[0273] Embodiment 2.3: Exemplarily, the base station indicates information of on-demand SSB and / or on-demand SIB1 based on a new format of DCI, eg, DCI format 2_10, or a new RNRI-scrambled DCI, eg, demand-RNTI-scrambled DCI 1_0, or DCI 2_9.

[0274] The DCI may be configured based on the CSS or the USS.

[0275] The DCI may include indication information of one cell, for example, the cell where the DCI is sent, or information indicating a cell ID of the DCI, and may also include indication information of multiple cells.

[0276] Except for the cell ID information, the information fields included in the DCI are similar to those in Embodiments 2.1 and 2.2 and will not be described again here.

[0277] Example 2.4: After receiving the DCI indication information and determining the on-demand signal state, the terminal may also determine the DCI effective time, i.e., the effective time of the on-demand signal state. Exemplarily, the corresponding effective time may also be determined based on a signaling indication or a predefined method. The effective time may be determined based on at least one of the following:

[0278] Cycle 1: the first SSB cycle after receiving the DCI;

[0279] Cycle 2: the blind detection cycle of the first P-RNTI-scrambled DCI 1_0 after receiving the DCI;

[0280] Cycle 3: the first paging cycle after receiving the DCI / next PF / PO;

[0281] The maximum values ​​of cycle 1, cycle 2 and cycle 3.

[0282] Based on this embodiment 2, a terminal supporting network energy saving receives the indication signaling and determines the corresponding on-demand signal status. It also determines the effective time and effective window based on a predefined method or the indication signaling, and receives / does not receive the corresponding SSB / SIB1 within the effective window.

[0283] Based on Example 1 or Example 2, the embodiment of the present invention mainly designs a related signaling indication method to indicate the status of the corresponding on-demand signal, which is beneficial to achieving network energy saving and achieving consistent understanding between the base station and the terminal.
