Method and apparatus for paging procedure in wireless communication system
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method may include: receiving, from a base station, paging early indication (PEI) configuration information including a parameter indicating a number of UE identity (ID) based paging subgroups; determining a paging subgroup ID corresponding to the UE, based on a maximum value of the parameter; monitoring PEI information on a PEI occasion, based on the PEI configuration information; and in case that the PEI information indicates the paging subgroup ID, monitoring paging downlink control information (DCI) on a paging occasion (PO).
1 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, system information including configuration information, the configuration information including paging information on a number of paging subgroups;
determining a UE identifier (ID), based on a 5G-S-Temporary Mobile Subscription Identifier (5G-S-TMSI) and an integer value greater than 1024, wherein the integer value is a multiple of a maximum number of paging subgroups configurable by the base station, the maximum number of paging subgroups being greater than or equal to the number of paging subgroups configured by the base station;
determining a paging subgroup ID of the UE, based on the UE ID and the paging information;
monitoring a paging early indication (PEI) occasion for reception of a PEI from the base station;
identifying that the PEI indicates a paging subgroup associated with the paging subgroup ID; and
based on identifying that the PEI indicates the paging subgroup, monitoring a paging occasion (PO) for reception of paging downlink control information (DCI) from the base station.
2 . The method of claim 1 , wherein the UE ID is determined, based on a modulo operation of the 5G-S-TMSI and the integer value.
3 . The method of claim 1 , wherein the integer value is equal to 8192.
4 . The method of claim 1 , wherein the integer value is equal to 32768 in case that an extended discontinuous reception (eDRX) is applied.
5 . The method of claim 1 , wherein the maximum number of paging subgroups is equal to 8.
6 . The method of claim 1 , further comprising:
determining the PO, based on a UE ID associated with the 5G-S-TMSI and a value equal to 1024 or 4096.
7 . The method of claim 6 , wherein the value is equal to 4096 in case that the UE operates in an eDRX.
8 . A user equipment (UE) in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor communicatively coupled to the at least one transceiver; and
at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor to cause the UE to:
receive, from a base station, system information including configuration information, the configuration information including paging information on a number of paging subgroups,
determine a UE identifier (ID), based on a 5G-S-Temporary Mobile Subscription Identifier (5G-S-TMSI) and an integer value greater than 1024, wherein the integer value is a multiple of a maximum number of paging subgroups configurable by the base station, the maximum number of paging subgroups being greater than or equal to the number of paging subgroups configured by the base station,
determine a paging subgroup ID of the UE, based on the UE ID and the paging information,
monitor a paging early indication (PEI) occasion for reception of a PEI from the base station,
identify that the PEI indicates a paging subgroup associated with the paging subgroup ID, and
based on identifying that the PEI indicates the paging subgroup, monitor a paging occasion (PO) for reception of paging downlink control information (DCI) from the base station.
9 . The UE of claim 8 , wherein the UE ID is determined, based on a modulo operation of the 5G-S-TMSI and the integer value.
10 . The UE of claim 8 , wherein the integer value is equal to 8192.
11 . The UE of claim 8 , wherein the integer value is equal to 32768 in case that an extended discontinuous reception (eDRX) is applied.
12 . The UE of claim 8 , wherein the maximum number of paging subgroups is equal to 8.
13 . The UE of claim 8 , wherein the UE is further caused to:
determine the PO, based on a UE ID associated with the 5G-S-TMSI and a value equal to 1024 or 4096.
14 . The UE of claim 13 , wherein the value is equal to 4096 in case that the UE operates in an eDRX.
15 . One or more non-transitory computer-readable storage media storing computer-executable instructions that, when executed by at least one processor of a user equipment (UE), cause the UE to perform operations, the operations comprising:
receiving, from a base station, system information including configuration information, the configuration information including paging information on a number of paging subgroups;
determining a UE identifier (ID), based on a 5G-S-Temporary Mobile Subscription Identifier (5G-S-TMSI) and an integer value greater than 1024, wherein the integer value is a multiple of a maximum number of paging subgroups configurable by the base station, the maximum number of paging subgroups being greater than or equal to the number of paging subgroups configured by the base station;
determining a paging subgroup ID of the UE, based on the UE ID and the paging information;
monitoring a paging early indication (PEI) occasion for reception of a PEI from the base station;
identifying that the PEI indicates a paging subgroup associated with the paging subgroup ID; and
based on identifying that the PEI indicates the paging subgroup, monitoring a paging occasion (PO) for reception of paging downlink control information (DCI) from the base station.
