Abstract

This application provides a paging method and a relevant device, and belongs to the technical field of communications. The paging method is applied to a terminal device, and includes: receiving configuration information sent by a base station, where the configuration information includes a mapping relationship between paging subgroups and WUS states and includes a total quantity of subgroups of the PO and/or a paging subgroup corresponding to the terminal device indicated by the base station; according to the total quantity of subgroups of the PO or the paging subgroup corresponding to a terminal device indicated by the base station, obtaining a first paging subgroup corresponding to the terminal device. According to the method, the problem of too high power consumption caused by additional monitoring of paging messages due to false paging alarms of the terminal device is solved.

First claim

What is claimed is:

1 . A paging method, applied to a terminal device and comprising:
receiving configuration information sent by a base station, wherein the configuration information comprises a mapping relationship between paging subgroups and wake up signal (WUS) states and comprises a total quantity of subgroups of a paging occasion (PO) and/or a paging subgroup corresponding to the terminal device indicated by the base station; according to the total quantity of subgroups of the PO or the paging subgroup corresponding to a terminal device indicated by the base station, obtaining a first paging subgroup corresponding to the terminal device, wherein the first paging subgroup corresponds to a first WUS state; and monitoring the WUS.

2 . The method according to claim 1 , wherein the WUS comprises one or more WUS states, and the method comprises:
monitoring a physical downlink control channel (PDCCH) at a paging occasion (PO) when the first WUS state is monitored.

3 . The method according to claim 1 , wherein the WUS comprises a plurality of WUS states, and the method further comprises:
when no first WUS state is monitored, entering or maintaining an idle state, or entering or maintaining an inactive state; or when a second WUS state is monitored, entering or maintaining an idle state, or entering or maintaining an inactive state, wherein the second WUS state corresponds to another paging subgroup different from the first paging subgroup.

4 . The method according to claim 2 , wherein when the WUS state is one WUS state, the mapping relationship between the paging subgroups and the WUS state specifically comprises:
the WUS state corresponds to one or more paging subgroups.

5 . The method according to claim 2 , wherein when the WUS states are a plurality of WUS states, the mapping relationship between the paging subgroups and the WUS states specifically comprises:
different WUS states respectively correspond to one or more different paging subgroups.

6 . The method according to claim 5 , wherein different WUS states correspond to different paging monitoring modes.

7 . The method according to claim 6 , wherein the paging monitoring modes comprise at least one of the followings:
monitoring WUS, and monitoring PEI when the first WUS state is monitored; monitoring WUS, and monitoring scheduling information of a PDCCH paging message at the PO when the first WUS state is monitored; monitoring PEI; and monitoring scheduling information of the PDCCH paging message at the PO.

8 . The method according to claim 7 , wherein the monitoring scheduling information of a physical downlink control channel (PDCCH) paging message at the paging occasion (PO) when the first WUS state is monitored specifically comprises:
monitoring PEI when the first WUS state is monitored; and monitoring scheduling information of the PDCCH paging message at the PO according to the indication of the PEI.

9 . The method according to claim 8 , wherein a user equipment identification UE ID corresponding to the terminal device is a first UE ID; and
the monitoring the PDCCH at the PO according to the indication of the PEI specifically comprises: monitoring scheduling information of the PDCCH paging message at the PO when the obtained UE ID carried by the PEI is the first UE ID.

10 . The method according to claim 9 , wherein the configuration information further comprises a total quantity of subgroups of the PO; and
the obtaining a first paging subgroup corresponding to the terminal device specifically comprises: obtaining a first paging subgroup corresponding to the terminal device according to the total quantity of subgroups of the PO.

11 . The method according to claim 10 , wherein the configuration information further comprises WUS configuration of the base station, and the monitoring WUS specifically comprises:
monitoring WUS when the WUS configuration of the base station supports the first paging subgroup.

12 . The method according to claim 11 , further comprising:
monitoring the WUS before the PO.

13 . The method according to claim 12 , further comprising:
monitoring the WUS before each PO according to a paging cycle.

14 . A paging method, applied to a base station and comprising:
sending configuration information, wherein the configuration information comprises a mapping relationship between paging subgroups and wake up signal (WUS) states and comprises a total quantity of subgroups of a paging occasion (PO) and/or a paging subgroup corresponding to the terminal device indicated by the base station; receiving a paging message, wherein the paging message comprises an identification of a paged terminal device; and sending WUS.

15 . The method according to claim 14 , wherein the WUS comprises one or more WUS states, and the WUS states correspond to one or more paging subgroups.

16 . The method according to claim 15 , wherein different WUS states correspond to different paging monitoring modes.

17 . The method according to claim 16 , wherein the paging monitoring modes comprise at least one of the followings:
monitoring WUS, and monitoring PEI when the first WUS state is monitored; monitoring WUS, and monitoring scheduling information of a PDCCH paging message at the PO when the first WUS state is monitored; monitoring PEI; and monitoring scheduling information of the PDCCH paging message at the PO.

18 . The method according to claim 17 , wherein the method further comprises:
obtaining a first paging subgroup corresponding to the terminal device according to the total quantity of subgroups of the PO.

19 . The method according to claim 18 , wherein the method further comprises:
sending a PDCCH at the PO; or sending the PEI before the PO, and sending the PDCCH at the PO.

20 . A base station, comprising:
one or more processors; and one or more memories, wherein the one or more memories have one or more computer programs stored therein, the one or more computer programs comprise an instruction, and the instruction, when executed by the one or more processors, enables the base station to implement operations comprising: sending configuration information, wherein the configuration information comprises a mapping relationship between paging subgroups and wake up signal (WUS) states and comprises a total quantity of subgroups of a paging occasion (PO) and/or a paging subgroup corresponding to the terminal device indicated by the base station; receiving a paging message, wherein the paging message comprises an identification of a paged terminal device; and sending WUS, wherein the WUS comprises one or more WUS states, and the WUS states correspond to one or more paging subgroups.
