[0034] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0035] Before describing the embodiments of the present application in detail, a paging mechanism in a new radio (NR) system is described.

[0036] The main function of Paging is that when the terminal device is in the Radio Resource Control (RRC) idle state (IDLE) or RRC deactivated state (INACTIVE), the network device can page the terminal device through a paging message, or notify the terminal device of system message changes or earthquake tsunami / public warning information through a short message. Of course, Paging is also applicable to terminal devices in the RRC connected state, that is, Paging is applicable to terminal devices in all RRC states.

[0037] The content of Paging may include the Physical Downlink Control Channel (PDCCH) scrambled by the Paging Radio Network Temporary Identifier (P-RNTI) and the Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH. The Paging message can be transmitted in the PDSCH; the size of the short message is 8 bits, and the short message can be in the PDCCH.

[0038] For terminal devices in RRC_IDLE state or RRC_INACTIVE state, since there is no data communication between the terminal device and the network device, in order to save the power of the terminal device, the terminal device can monitor the Paging channel discontinuously, that is, adopt the Paging discontinuous reception (DRX) mechanism. Under the PagingDRX mechanism, the terminal device only needs to monitor paging during one paging occasion (Paging Occasion, PO) in each DRX cycle. PO includes multiple PDCCH monitoring opportunities, and PO can be composed of multiple time slots. Paging Frame (Paging Frame, PF) refers to a radio frame. The duration of FP is 10ms. A PF can contain multiple POs or the starting positions of multiple POs.

[0039] The DRX cycle is determined by the common cycle in the system broadcast sent by the network device and the dedicated cycle configured in the high-level signaling. The terminal device can select the minimum cycle of the two as the DRX cycle; wherein the high-level signaling can be the Non-Access Stratum (NAS) signaling. From the perspective of the network device, a DRX cycle can have multiple POs, and the location where the terminal device monitors the PO is related to the identifier (ID) of the terminal device. Specifically, the PF and PO of a terminal device in a DRX cycle are determined as follows (TS 38.304):

[0040] The PF system frame number (SFN) is determined by the following formula:

[0041] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) (1)

[0042] The index of the PO in a PF, Index_(i_s), is determined by the following formula:

[0043] i_s=floor(UE_ID / N)mod Ns (2)

[0044] Among them, T is the DRX cycle of the terminal device to receive Paging. The network device will broadcast a default DRX cycle; if the network device configures a terminal device-specific DRX cycle for the terminal device through RRC signaling / high-layer signaling, the minimum of the DRX cycle broadcast by the network device and the terminal device-specific DRX cycle configured by RRC signaling / high-layer signaling is used as the DRX cycle of the terminal device. If the network device does not configure a terminal device-specific DRX cycle for the terminal device through RRC signaling / high-layer signaling, the DRX cycle broadcast by the network device is used as the DRX cycle of the UE. N is the number of PFs contained in a DRX cycle. Ns is the number of POs contained in a PF. PF-offset is the time domain offset used to determine PF. UE_ID is 5G-S-TMSI mod 1024.

[0045] The configuration of the above parameters is as follows:

[0046]

[0047] For any terminal device, according to the above formula (1) and formula (2), the position of PF in a DRX cycle and the index of PO can be determined. In the protocol TS 38.304, it is stipulated that PO is composed of multiple PDCCH monitoring occasions. A PO contains X PDCCH monitoring occasions, where X is equal to the number of synchronization signal blocks (SSB) actually sent in the broadcast of the master information block (MIB).

[0048] After the terminal device determines the PF, the index of the PO, and the number of PDCCH monitoring occasions in the PO, it is also necessary to determine the starting position of the first PDCCH monitoring occasion of the PO through the configuration parameters sent by the network device; wherein the starting position can be configured through the high-level signaling sent by the network device, or obtained based on the PO index. The terminal device blindly detects the Paging message based on the determined PO.

[0049] Currently, the reception of Paging messages includes blind detection of PDCCH and the corresponding PDSCH. At the same time, for non-connected terminal devices, the terminal devices also need to perform synchronization operations before blind detection of PDCCH. For terminal devices with good channel quality (such as higher signal to interference plus noise ratio (SINR)), fewer synchronization signals (SS) bursts may be needed to complete synchronization, while for terminal devices with poor channel quality (such as lower SINR), more SS bursts may be needed to complete synchronization.

[0050] In the 3GPP standard discussion, the following can be performed for power saving paging optimization:

[0051] 1. Paging based on terminal device groups, that is, the terminal devices assigned to the same PO are further divided into multiple groups. The terminal device group indication can avoid the problem of paging false alarms between terminal devices in different groups.

[0052] 2. Send a paging early indication (PEI) or a wake-up signal (WUS) before PO to reduce PO monitoring, that is, the network device can send PEI or WUS before PO to notify the terminal device whether to perform paging monitoring or reception on the subsequent PO.

[0053] The applicant found in the implementation process that the combination of the above two methods can achieve greater energy saving gains. One of the methods is to use PEI to indicate whether each terminal device group on a PO needs to monitor or receive paging. If PEI is designed based on PDCCH and needs to support more terminal device groups, and the size of PDCCH DCI is limited, the network device can send multiple PEIs before PO to indicate different terminal device groups separately.

[0054] In the R17 project, the 3GPP RAN Plenary Meeting agreed to further enhance the energy saving of terminal equipment (RP-193239), that is, to reduce the number of unnecessary paging received by terminal equipment by designing an enhanced Paging mechanism.

[0055] In the process of implementing the paging method, the applicant discovered that there are problems of large system overhead and high energy consumption of terminal devices; the reason is: when there are many terminal devices in the system, the network device may not assign each terminal device to a different PO, that is, there may be a situation where multiple terminal devices correspond to one PO. In this scenario, if the network device needs to page a terminal device on a PO, since the PO may correspond to multiple terminal devices, it may cause the terminal device that does not need to receive the paging message to perform additional blind detection, such as blind detection of PDCCH and PDSCH corresponding to PDCCH. The additional blind detection performed by the terminal device that does not need to receive the paging message can be called a paging false alarm. Therefore, how to reduce the probability of paging false alarms and reduce unnecessary paging message reception by the terminal device to reduce system overhead and reduce the energy consumption of the terminal device is a problem that needs to be solved.

[0070] An optional processing flow of the paging method provided in the embodiment of the present application is as follows: Figure 2 As shown, the following steps may be included:

[0071] Step S201: The terminal device determines the grouping information of the terminal device.

[0072] The grouping information is obtained by grouping at least two terminal devices corresponding to one paging occasion. For example, one paging occasion corresponds to N terminal devices, where N is an integer greater than 1; the N terminal devices are grouped, and the terminal devices belonging to the same group can monitor the corresponding PDCCH channel at the same time. The number of groups that can be divided into the N terminal devices corresponding to one paging occasion is determined by the network device or predefined. When a paging frame includes multiple paging occasions, the number of groups that can be divided into the terminal devices corresponding to the multiple paging occasions can be the same or different.

[0073] In some embodiments, the grouping information of the terminal device is configured by a network device. For example, the terminal device receives first configuration information sent by a network device, and the first configuration information is used by the terminal device to determine the grouping information of the terminal device. The first configuration information can be carried in a system broadcast message or in an RRC dedicated signaling.

[0074] In some other embodiments, the grouping information of the terminal devices is predefined.

[0075] Step S202: The terminal device determines a paging parameter based on the grouping information, and the paging parameter is used by the terminal device to perform paging message detection.

[0076] In the embodiment of the present application, the paging parameters may include: a time domain offset (PF_offset) of a paging frame and a PDCCH monitoring timing for a terminal device to perform paging message detection.

[0077] The following describes the paging method provided in an embodiment of the present application by taking the paging parameter as the time domain offset of the paging frame, the paging parameter as the PDCCH monitoring timing for the terminal device to perform paging message detection, and the paging parameter as PEI (the PEI is used to indicate whether the terminal device performs paging detection at the subsequent paging timing) as examples.

[0078] In the case where the paging parameter is the time domain offset of the paging frame, an optional processing flow of the paging method provided in the embodiment of the present application is as follows: Figure 3 As shown, it may include:

[0079] Step S301: The terminal device determines the grouping information of the terminal device in a predefined manner or through first configuration information sent by a network device.

[0080] In an embodiment of the present application, multiple terminal devices corresponding to a PO are divided into N groups, where N is an integer greater than 1.

[0081] Step S302: The terminal device receives third configuration information sent by the network device.

[0082] In the embodiment of the present application, the third configuration information is used by the terminal device to determine the number of time domain offsets of the paging frame. The third configuration information and the first configuration information may be the same configuration information or different configuration information.

[0083] In some embodiments, the number of time domain offsets is equal to the number of groups obtained by grouping terminal devices corresponding to a paging occasion included in the paging frame. If multiple terminal devices corresponding to a PO are divided into N groups, the number of time domain offsets is also N.

[0084] In other embodiments, the number of time domain offsets is equal to the number of groups obtained by grouping terminal devices corresponding to a paging occasion included in the paging frame plus 1. If multiple terminal devices corresponding to a PO are divided into N groups, the number of time domain offsets is N+1.

[0085] In an embodiment of the present application, the third configuration information may include N PF_offsets, which are used by the terminal device to determine that the number of time domain offsets is N; or, the third configuration information may include N+1 PF_offsets, which are used by the terminal device to determine that the number of time domain offsets is N+1.

[0086] In a specific implementation, in addition to being used by the terminal device to determine the number of time domain offsets of the paging frame, the third configuration information may also include at least one of the following:

[0087] 1) A set of control resource groups (ControlResourceSet) and Paging search space;

[0088] 2) 1 first PDCCH-Monitoring OccasionOfPO sequence, where the first PDCCH-Monitoring OccasionOfPO sequence is used to indicate the first PDCCH monitoring opportunity corresponding to each PO within a PF.

[0089] Step S303: The terminal device determines a mapping relationship between a time domain offset of a paging frame and grouping information.

[0090] In some embodiments, the mapping relationship between the time domain offset of the paging frame and the grouping information is configured by a network device; for example, the terminal device receives second configuration information sent by the network device, and the second configuration information includes the mapping relationship between the time domain offset of the paging frame and the grouping information. Alternatively, the mapping relationship between the time domain offset of the paging frame and the grouping information is predefined.

[0091] In some embodiments, if the number of time domain offsets of a paging frame is N, and the terminal devices corresponding to one PO are divided into N groups, then each terminal device group corresponds to a time domain offset of the paging frame, and the terminal devices that are not grouped correspond to the default time domain offset of the paging frame. For example, the first time domain offset corresponds to the first terminal device group, the second time domain offset corresponds to the second terminal device group, and the Nth time domain offset corresponds to the Nth terminal device group. If a terminal device is not grouped, that is, the terminal device does not belong to any of the N terminal device groups, then the terminal device corresponds to the default time domain offset; the default time domain offset may be configured by the network device or may be pre-agreed; the default time domain offset may be any one of the N time domain offsets, such as the default time domain offset is the first of the N time domain offsets.

[0092] In other embodiments, if the number of time domain offsets of a paging frame is N+1, and the terminal devices corresponding to one PO are divided into N groups, then the terminal devices that are not grouped correspond to the first time domain offset of the paging frame; and each terminal device group corresponds to a time domain offset other than the first time domain offset of the paging frame. For example, the first time domain offset corresponds to the terminal devices that are not grouped, the second time domain offset corresponds to the first terminal device group, and the N+1th time domain offset corresponds to the Nth terminal device group.

[0093] Step S304: The terminal device determines a paging frame based on a time domain offset of the paging frame corresponding to the grouping information of the terminal device.

[0094] In specific implementation, the terminal device determines the terminal device group to which it belongs; then determines the time domain offset of the paging frame corresponding to the terminal device group described by itself based on the mapping relationship between the time domain offset of the paging frame and the group information; finally, determines the paging frame based on the determined time domain offset.

[0095] In some embodiments, the mapping relationship between the time domain offset of the paging frame and the packet information is as follows: Figure 4 As shown, taking N=T / 4 as an example, a PO includes 4 terminal device groups, and the PF_offsets corresponding to the 4 terminal device groups are: 0, 1, 2 and 3 respectively; then terminal device group 1 uses the PF_offset value of 0 to calculate the paging frame, terminal device group 2 uses the PF_offset value of 1 to calculate the paging frame, terminal device group 3 uses the PF_offset value of 2 to calculate the paging frame, and terminal device group 4 uses the PF_offset value of 3 to calculate the paging frame. If the terminal device described in the embodiment of the present application determines that it belongs to terminal device group 4, the terminal device uses the PF_offset value of 3 to calculate the paging frame.

[0096] Step S305: The terminal device performs paging message detection based on the determined paging frame.

[0097] In specific implementation, the terminal device detects the paging message by monitoring the PDCCH encrypted by the P-RNTI.

[0098] In an embodiment of the present application, the terminal device determines the paging frame for detecting the paging message according to the terminal device group to which it belongs. By limiting the paging frame for detecting the paging message by the terminal device, the number of unnecessary paging message detections by the terminal device can be reduced, the probability of false paging alarms can be reduced, and the power consumption of the terminal device can be saved.

[0099] In the case where the paging parameter is a PDCCH monitoring opportunity for the terminal device to detect a paging message, an optional processing flow of the paging method provided in the embodiment of the present application is as follows: Figure 5 As shown, it may include:

[0100] Step S401: The terminal device determines the grouping information of the terminal device in a predefined manner or through first configuration information sent by a network device.

[0101] In an embodiment of the present application, multiple terminal devices corresponding to a PO are divided into N groups, where N is an integer greater than 1.

[0102] Step S402: The terminal device receives fourth configuration information sent by the network device.

[0103] In the embodiment of the present application, the fourth configuration information and the first configuration information may be the same configuration information or different configuration information.

[0104] In a specific implementation, the fourth configuration information may include at least one of the following:

[0105] 1) A set of control resource groups (ControlResourceSet) and Paging search space;

[0106] 2) a first PDCCH-Monitoring OccasionOfPO sequence, where the first PDCCH-Monitoring OccasionOfPO sequence is used to indicate the first PDCCH monitoring opportunity corresponding to each PO within a PF;

[0107] 3) The number S of SSBs sent by the network device at the same time.

[0108] Step S403: The terminal device determines the number of PDCCH monitoring opportunities for performing paging message detection.

[0109] In some embodiments, the terminal device determines the number of PDCCH monitoring opportunities for paging message detection according to the fourth configuration information, which is equal to the product of the number of groups N obtained by grouping the terminal devices corresponding to the paging opportunities and the number of synchronization signal blocks S actually sent by the network device. That is, the number of PDCCH monitoring opportunities for paging message detection by the terminal device is equal to N*S.

[0110] In other embodiments, the terminal device determines the number of PDCCH monitoring opportunities for paging message detection according to the fourth configuration information, which is equal to the product of the number of groups N obtained by grouping the terminal devices corresponding to the paging opportunity plus 1 and the number of synchronization signal blocks S actually sent by the network device. That is, the number of PDCCH monitoring opportunities for paging message detection by the terminal device is equal to (N+1)*S.

[0111] Step S404: The terminal device determines the PDCCH for the terminal device to perform paging message detection based on the grouping information of the terminal device.

[0112] In some embodiments, if the number of PDCCH monitoring opportunities for the terminal device to perform paging message detection is equal to N*S, each terminal device group corresponds to S consecutive PDCCH monitoring opportunities. For example, the first terminal device group corresponds to the first group of S consecutive PDCCH monitoring opportunities in the N*S PDCCH monitoring opportunities, the second terminal device group corresponds to the second group of S consecutive PDCCH monitoring opportunities in the N*S PDCCH monitoring opportunities, and the Nth terminal device group corresponds to the Nth group of S consecutive PDCCH monitoring opportunities in the N*S PDCCH monitoring opportunities.

[0113] The terminal device determines the PDCCH monitoring timing for detecting the paging message according to the terminal device group information it belongs to. For example, if the terminal device belongs to the second terminal device group, the terminal device determines the PDCCH monitoring timing for detecting the paging message as: the second group of S consecutive PDCCH monitoring timings.

[0114] If the terminal device is not grouped, that is, the terminal device does not belong to any of the N terminal device groups, the terminal device determines that the PDCCH monitoring opportunities for detecting the paging message are: the first group of S consecutive PDCCH monitoring opportunities.

[0115] like Figure 6 As shown, taking the case where the terminal devices corresponding to a paging opportunity are divided into N=3 groups and the number of SSBs actually sent by the network device is S=4 as an example, the number of PDCCH monitoring opportunities that the terminal devices in a paging opportunity can detect paging messages is N*S=12, and the first PDCCH monitoring opportunity corresponding to the paging opportunity is determined according to the configuration parameter first PDCCH-Monitoring OccasionOfPO sequence. Then the first terminal device group corresponds to the 1st to 4th PDCCH monitoring opportunities, that is, the terminal devices in the first terminal device group detect paging messages at the 1st to 4th PDCCH monitoring opportunities. The second terminal device group corresponds to the 5th to 8th PDCCH monitoring opportunities, that is, the terminal devices in the second terminal device group detect paging messages at the 5th to 8th PDCCH monitoring opportunities. The third terminal device group corresponds to the 9th to 12th PDCCH monitoring opportunities, that is, the terminal devices in the third terminal device group detect paging messages at the 9th to 12th PDCCH monitoring opportunities. The ungrouped terminal devices detect the paging message during the 1st to 4th PDCCH monitoring opportunities.

[0116] In other embodiments, if the number of PDCCH monitoring opportunities for the terminal device to detect paging messages is equal to (N+1)*S, each terminal device group corresponds to S consecutive PDCCH monitoring opportunities other than the first S consecutive PDCCH monitoring opportunities included in the paging opportunity. For example, the first terminal device group corresponds to the second group of S consecutive PDCCH monitoring opportunities in the (N+1)*S PDCCH monitoring opportunities, the second terminal device group corresponds to the third group of S consecutive PDCCH monitoring opportunities in the (N+1)*S PDCCH monitoring opportunities, and the Nth terminal device group corresponds to the N+1th group of S consecutive PDCCH monitoring opportunities in the N*S PDCCH monitoring opportunities.

[0117] The terminal device determines the PDCCH monitoring timing for detecting the paging message according to the terminal device group information it belongs to. For example, if the terminal device belongs to the second terminal device group, the terminal device determines the PDCCH monitoring timing for detecting the paging message as: the third group of S consecutive PDCCH monitoring timings.

[0118] If the terminal device is not grouped, that is, the terminal device does not belong to any of the N terminal device groups, the terminal device determines that the PDCCH monitoring opportunities for detecting the paging message are: the first group of S consecutive PDCCH monitoring opportunities.

[0119] like Figure 7 As shown, taking the case where the terminal devices corresponding to a paging opportunity are divided into N=3 groups and the number of SSBs actually sent by the network device is S=4 as an example, the number of PDCCH monitoring opportunities for the terminal devices in a paging opportunity to detect paging messages is (N+1)*S=16, and the first PDCCH monitoring opportunity corresponding to the paging opportunity is determined according to the configuration parameter firstPDCCH-Monitoring OccasionOfPO sequence. Then the ungrouped terminal devices detect paging messages at the 1st to 4th PDCCH monitoring opportunities. The first terminal device group corresponds to the 5th to 8th PDCCH monitoring opportunities, that is, the terminal devices in the first terminal device group detect paging messages at the 5th to 8th PDCCH monitoring opportunities. The second terminal device group corresponds to the 9th to 12th PDCCH monitoring opportunities, that is, the terminal devices in the second terminal device group detect paging messages at the 9th to 12th PDCCH monitoring opportunities. The third terminal device group corresponds to the 13th to 16th PDCCH monitoring opportunities, that is, the terminal devices in the third terminal device group detect paging messages at the 13th to 16th PDCCH monitoring opportunities.

[0120] Step S405: The terminal device performs paging message detection based on the determined PDCCH monitoring opportunity.

[0121] In specific implementation, the terminal device detects the paging message only during the S PDCCH monitoring opportunities corresponding to the terminal device group to which it belongs.

[0122] In an embodiment of the present application, the terminal device determines the PDCCH monitoring timing for detecting paging messages according to the terminal device group to which it belongs. By limiting the PDCCH monitoring timing for detecting paging messages by the terminal device, the number of unnecessary paging message detections by the terminal device can be reduced, the probability of false paging alarms can be reduced, and the power consumption of the terminal device can be saved.

[0123] In the case where the paging parameter is a paging advance indication, an optional processing flow of the paging method provided in the embodiment of the present application is as follows: Figure 8 As shown, it may include:

[0124] Step S901: The terminal device determines the grouping information of the terminal device in a predefined manner or through first configuration information sent by a network device.

[0125] In an embodiment of the present application, multiple terminal devices corresponding to a PO are divided into N groups, where N is an integer greater than 1.

[0126] Step S902: The terminal device receives fifth configuration information sent by the network device.

[0127] In the embodiment of the present application, the fifth configuration information and the first configuration information may be the same configuration information or different configuration information.

[0128] In some embodiments, the fifth configuration information is used to configure parameters related to the PEI.

[0129] In a specific implementation, the PEI-related parameters may include at least one of the following: the search space of the PEI; the minimum time offset (minoffset) before the last PDCCH listening opportunity corresponding to the PEI; the correspondence between the PEI and the group information of the terminal device; the number of synchronization signal blocks actually sent by the network device. Among them, the correspondence between the PEI and the group information of the terminal device can be that one PEI is used to indicate whether at least one terminal device group performs paging detection at the paging opportunity, that is, one PEI is used to indicate whether the terminal devices in one or more terminal device groups perform paging detection at the subsequent PO; different PEIs are used to indicate whether different terminal device groups perform paging detection at the subsequent paging opportunities. N terminal device groups of a PO can correspond to one or more PEIs.

[0130] In some embodiments, the correspondence between the PEI and the grouping information of the terminal device may also be predefined.

[0131] In some embodiments, the number of PDCCH monitoring occasions corresponding to all PEIs sent by the network device before the paging occasion is: the product of the number of PEIs to be sent by the network device and the number of synchronization signal blocks actually sent by the network device.

[0132] Step S903: The terminal device determines a PDCCH monitoring timing for the terminal device to receive the PEI according to the grouping information of the terminal device.

[0133] In some embodiments, the terminal device determines the PEI corresponding to the terminal device group based on the correspondence between the PEI and the group information of the terminal device; the S consecutive PDCCH monitoring opportunities corresponding to the PEI determined by the terminal device are the PDCCH monitoring opportunities for the terminal device to receive the PEI; wherein S is the number of SSBs sent by the network device.

[0134] In some embodiments, before the network device sends a paging opportunity, it sends M PEIs, each PEI corresponds to S consecutive PDCCH monitoring opportunities, then the PDCCH monitoring opportunity corresponding to the nth PEI among the M PEIs sent by the network device is: starting from the minimum time offset before the paging opportunity, from the (n-1)*S+1th PDCCH monitoring opportunity to the n*Sth PDCCH monitoring opportunity, where 1≤n≤M.

[0135] Alternatively, in some other embodiments, before the network device sends a paging opportunity, it sends M PEIs, each PEI corresponds to S consecutive PDCCH monitoring opportunities, then the PDCCH monitoring opportunity corresponding to the nth PEI among the M PEIs sent by the network device is: starting from the minimum time offset before the paging opportunity, from the (Mn)*S+1th PDCCH monitoring opportunity to the (M-n+1)*Sth PDCCH monitoring opportunity, where 1≤n≤M. In this scenario, the correspondence between PEI and PDCCH monitoring opportunity is as follows: Fig. 9 As shown: the PDCCH monitoring timing corresponding to the first PEI among the M PEIs is: taking the minimum time offset before the paging opportunity as the starting position, and moving forward from the (M-1)*S+1th PDCCH monitoring timing to the M*Sth PDCCH monitoring timing; the PDCCH monitoring timing corresponding to the second PEI among the M PEIs is: taking the minimum time offset before the paging opportunity as the starting position, and moving forward from the (M*S-2S+1)th PDCCH monitoring timing to the (M*SS)th PDCCH monitoring timing; and so on, the PDCCH monitoring timing corresponding to the Mth PEI among the M PEIs is: taking the minimum time offset before the paging opportunity as the starting position, and moving forward for S consecutive PDCCH monitoring timings.

[0136] In some embodiments, the method may further include:

[0137] Step S904: The terminal device receives PEI at the determined PDCCH monitoring opportunity.

[0138] In some embodiments, the way in which the terminal device receives PE is similar to the way in which the terminal device receives paging DCI; specifically, the network device can repeatedly send PEI at S PDCCH monitoring opportunities, and the terminal device assumes that the PEI is repeatedly sent in different SSB beam directions at the determined S PDCCH monitoring opportunities. Then the terminal chooses which SSB beam direction to receive PEI depends on the UE implementation.

[0139] Step S905: The terminal device determines whether it needs to monitor or receive a paging message on a subsequent PO according to the indication of the received PEI.

[0140] In some embodiments, if the PEI received by the terminal device indicates receiving a paging message, the terminal device monitors or receives the paging message on the PO after receiving the PEI. If the PEI received by the terminal device indicates not receiving a paging message, the terminal device does not monitor or receive the paging message on the PO after receiving the PEI.

[0141] It should be noted that the PEI in the embodiment of the present application can also be replaced by a wake-up signal WUS, that is, the network device indicates whether the terminal device is listening to or receiving a paging message on the PO by sending a WUS. The process of the network device indicating whether the terminal device is listening to or receiving a paging message on the PO by sending a WUS is the same as the process of the network device indicating whether the terminal device is listening to or receiving a paging message on the PO by sending a PEI, except that PEI is replaced by WUS, which will not be repeated here.

[0142] Another optional processing flow of the paging method provided in the embodiment of the present application is as follows: Fig.10 As shown, the following steps may be included:

[0143] Step S501: The network device sends first configuration information.

[0144] In some embodiments, the first configuration information is used by a terminal device to determine group information of the terminal device, and to determine a paging parameter for paging message detection based on the group information.

[0145] In the case where the paging parameter includes a time domain offset of a paging frame, the method may further include:

[0146] Step S502: The network device sends second configuration information, where the second configuration information is used by the terminal device to determine a mapping relationship between a time domain offset of a paging frame and grouping information.

[0147] Step S503: The network device sends third configuration information, where the third configuration information is used by the terminal device to determine the number of time domain offsets of the paging frame.

[0148] In some embodiments, the number of time domain offsets of the paging frame is equal to the number of groups obtained by grouping terminal devices corresponding to a paging occasion included in the paging frame. Each terminal device group corresponds to a time domain offset of the paging frame; the terminal devices that are not grouped correspond to the default time domain offset of the paging frame.

[0149] In some other embodiments, the number of time domain offsets of the paging frame is equal to the number of groups obtained by grouping terminal devices corresponding to a paging occasion included in the paging frame plus 1. The ungrouped terminal devices correspond to the first time domain offset of the paging frame; each terminal device group corresponds to a time domain offset other than the first time domain offset of the paging frame.

[0150] In the case where the paging parameters include a downlink control channel PDCCH monitoring opportunity for the terminal device to detect paging messages, among the PDCCH monitoring opportunities included in the paging opportunities corresponding to the terminal device, every S consecutive PDCCH monitoring opportunities starting from the first PDCCH monitoring opportunity correspond to a terminal device group; S is the number of synchronization signal blocks actually sent by the network device.

[0151] The number of PDCCH monitoring opportunities for the terminal device to detect the paging message is equal to the product of the number of groups N obtained by grouping the terminal devices corresponding to the paging opportunity and the number of synchronization signal blocks S actually sent by the network device. Each terminal device group corresponds to S consecutive PDCCH monitoring opportunities, and the terminal devices that are not grouped correspond to the first S consecutive PDCCH monitoring opportunities included in the paging opportunity.

[0152] Alternatively, the number of PDCCH monitoring opportunities for the terminal device to detect the paging message is equal to the product of the number of groups N obtained by grouping the terminal devices corresponding to the paging opportunity plus 1 and the number of synchronization signal blocks S actually sent by the network device. The terminal devices that are not grouped correspond to the first S consecutive PDCCH monitoring opportunities included in the paging opportunity, and each terminal device group corresponds to S consecutive PDCCH monitoring opportunities other than the first S consecutive PDCCH monitoring opportunities included in the paging opportunity.

[0153] When the paging parameter is PEI, the PEI is used to indicate whether the terminal device performs paging detection at the paging opportunity.

[0154] In some embodiments, after executing step S501, the method may further include:

[0155] Step S504: The network device sends fifth configuration information to the terminal device, where the fifth configuration information is used to configure parameters related to the PEI.

[0156] In some embodiments, the PEI-related parameters may include at least one of the following: the search space of the PEI; the minimum time offset of the last PDCCH listening opportunity corresponding to the PEI before the paging opportunity; the correspondence between the PEI and the group information of the terminal device; the number of synchronization signal blocks actually sent by the network device. Among them, the correspondence between the PEI and the group information of the terminal device can be that one PEI is used to indicate whether at least one terminal device group performs paging detection at the paging opportunity, that is, one PEI is used to indicate whether the terminal devices in one or more terminal device groups perform paging detection at the subsequent PO; different PEIs are used to indicate whether different terminal device groups perform paging detection at the subsequent paging opportunities. N terminal device groups of a PO can correspond to one or more PEIs.

[0157] In some embodiments, the number of PDCCH monitoring opportunities corresponding to all PEIs sent by the network device before the paging opportunity is: the product of the number of PEIs to be sent by the network device and the number of synchronization signal blocks actually sent by the network device. Specifically, the PDCCH monitoring opportunity corresponding to the nth PEI among the M PEIs sent by the network device before the paging opportunity is: starting from the minimum time offset before the paging opportunity and moving forward from the (n-1)*S+1th PDCCH monitoring opportunity to the n*Sth PDCCH monitoring opportunity, where 1≤n≤M.

[0158] Alternatively, in some other embodiments, the PDCCH monitoring opportunity corresponding to the nth PEI among the M PEIs sent by the network device before the paging opportunity is: starting from the minimum time offset before the paging opportunity and moving forward from the (Mn)*S+1th PDCCH monitoring opportunity to the (M-n+1)*Sth PDCCH monitoring opportunity, where 1≤n≤M. In this scenario, the corresponding relationship between PEI and PDCCH monitoring opportunity is as follows: Fig. 9As shown: the PDCCH monitoring timing corresponding to the first PEI among the N PEIs is: taking the minimum time offset before the paging opportunity as the starting position, and moving forward from the (M-1)*S+1th PDCCH monitoring timing to the M*Sth PDCCH monitoring timing; the PDCCH monitoring timing corresponding to the second PEI among the M PEIs is: taking the minimum time offset before the paging opportunity as the starting position, and moving forward from the (M*S-2S+1)th PDCCH monitoring timing to the (M*SS)th PDCCH monitoring timing; and so on, the PDCCH monitoring timing corresponding to the Mth PEI among the M PEIs is: taking the minimum time offset before the paging opportunity as the starting position, and moving forward for S consecutive PDCCH monitoring timings.

[0159] In a specific implementation, the network device traverses each synchronization signal block and sends the first PEI; the network device then traverses each synchronization signal block and sends the second PEI until all PEIs are sent. The PDCCH monitoring timing for the terminal device to receive the PEI is: the S consecutive PDCCH monitoring timings corresponding to the PEI corresponding to the grouping information of the terminal device, and S is the number of synchronization signal blocks actually sent by the network device. For the S consecutive PDCCH monitoring timings corresponding to a PEI sent by the network device, the network device sends the PEI through the Kth synchronization signal block at the Kth PDCCH monitoring timing, 1≤K≤S.

[0160] The paging method, electronic device and storage medium provided by the embodiment of the present application include: the terminal device determines the grouping information of the terminal device, the grouping information is obtained by grouping at least two terminal devices corresponding to a paging opportunity; the terminal device determines the paging parameters based on the grouping information, and the paging parameters are used by the terminal device to detect the paging message. In this way, the terminal device determines the paging parameters for detecting the paging message according to the terminal device group to which it belongs, and by limiting the PDCCH monitoring opportunity or paging frame for the terminal device to detect the paging message, the number of unnecessary paging message detections by the terminal device can be reduced, the probability of paging false alarms can be reduced, and the power consumption of the terminal device can be saved.
