The UE may initiate an update of the paging subgroup ID assigned to the UE by transmitting paging assistance information to the AMF. The paging assistance information may include an expected paging probability of the UE. The base station may initiate an update of the paging subgroup ID assigned to the UE based on the change of RRC connection between the UE and the base station. The core network including the AMF may transmit an updated paging subgroup ID to the UE. The core network including the AMF may configure a set of candidate subgroups associated with the UE, and the base station may update the paging subgroup ID of the UE based on releasing the RRC connection to the RRC inactive state. ## Claims ### Claim 1 An apparatus for wireless communication at a user equipment (UE), comprising: memory; and at least one processor coupled to the memory, the at least one processor configured to cause the UE to: transmit, to a network, a paging assistance information; receive, from the network, a subgroup identifier (ID) of the UE in response to transmission of the paging assistance information; receive, from a base station, system information indicating a number of UE subgroups assigned by the network; and monitor a paging channel using the subgroup ID based at least in part on receiving the subgroup ID, the subgroup ID having a value within a range corresponding to the number of the UE subgroups assigned by the network. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising a transceiver coupled to the at least one processor, and wherein the at least one processor is configured to cause the UE to transmit the paging assistance information or receive the subgroup ID via the transceiver. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the at least one processor is configured to cause the UE to transmit the paging assistance information in one or more of a registration request message or a registration update message, and the subgroup ID is received in a registration acceptance message from the network. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the subgroup ID is in a radio resource control (RRC) release message from the base station. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the at least one processor is further configured to cause the UE to: transmit, to the network, a UE capability indicating whether the UE supports subgrouping assigned by the network. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the paging assistance information includes at least one of a paging probability, a mobility profile, or a power profile. ### Claim 7 A method of wireless communication at a user equipment (UE), comprising: transmitting, to a network, a paging assistance information; receiving, from the network, a subgroup identifier (ID) of the UE in response to transmitting the paging assistance information; receiving, from a base station, system information indicating a number of UE subgroups assigned by the network; and monitoring a paging channel using the subgroup ID based at least in part on receiving the subgroup ID, the subgroup ID having a value within a range corresponding to the number of the UE subgroups assigned by the network. ### Claim 8 (depends on 7) The method of claim 7, wherein transmitting the paging assistance information includes transmitting the paging assistance information in one or more of a registration request message or a registration update message, and the subgroup ID is received in a registration acceptance message from the network. ### Claim 9 (depends on 7) The method of claim 7, wherein the subgroup ID is received in a radio resource control (RRC) release message from the base station. ### Claim 10 (depends on 7) The method of claim 7, further comprising: transmitting, to the network, a UE capability indicating whether the UE supports subgrouping assigned by the network. ### Claim 11 (depends on 7) The method of claim 7, wherein the paging assistance information includes at least one of a paging probability, a mobility profile, or a power profile. ### Claim 12 An apparatus for wireless communication at a user equipment (UE), comprising: means for transmitting, to a network, a paging assistance information; means for receiving, from the network, a subgroup identifier (ID) of the UE in response to transmitting the paging assistance information; means for receiving, from a base station, system information indicating a number of UE subgroups assigned by the network; and means for monitoring a paging channel using the subgroup ID based at least in part on receiving the subgroup ID, the subgroup ID having a value within a range corresponding to the number of the UE subgroups assigned by the network. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the means for transmitting the paging assistance information are configured to transmit the paging assistance information in one or more of a registration request message or a registration update message, and the subgroup ID is received in a registration acceptance message from the network. ### Claim 14 (depends on 12) The apparatus of claim 12, wherein the subgroup ID is in a radio resource control (RRC) release message from the base station. ### Claim 15 (depends on 12) The apparatus of claim 12, further comprising: means for transmitting, to the network, a UE capability indicating whether the UE supports subgrouping assigned by the network. ### Claim 16 (depends on 12) The apparatus of claim 12, wherein the paging assistance information includes at least one of a paging probability, a mobility profile, or a power profile. ### Claim 17 A non-transitory computer-readable medium storing computer executable code at a user equipment (UE), the code when executed by at least one processor causes the UE to: transmit, to a network, a paging assistance information; receive, from the network, a subgroup identifier (ID) of the UE in response to transmission of the paging assistance information; receive, from a base station, system information indicating a number of UE subgroups assigned by the network; and monitor a paging channel using the subgroup ID based at least in part on receiving the subgroup ID, the subgroup ID having a value within a range corresponding to the number of the UE subgroups assigned by the network. ### Claim 18 (depends on 17) The non-transitory computer-readable medium of claim 17, wherein the code, when executed by the at least one processor causes the UE to transmit the paging assistance information in one or more of a registration request message or a registration update message, and the subgroup ID is received in a registration acceptance message from the network. ### Claim 19 (depends on 17) The non-transitory computer-readable medium of claim 17, wherein the subgroup ID is in a radio resource control (RRC) release message from the base station. ### Claim 20 (depends on 17) The non-transitory computer-readable medium of claim 17, wherein the code, when executed by the at least one processor further causes the UE to: transmit, to the network, a UE capability indicating whether the UE supports subgrouping assigned by the network. ### Claim 21 (depends on 17) The non-transitory computer-readable medium of claim 17, wherein the paging assistance information includes at least one of a paging probability, a mobility profile, or a power profile.
