one or more memories; and
one or more processors, coupled to the one or more memories, configured to cause the UE to:
establish a first user equipment (UE) identifier (ID) associated with a pre-paging configuration, wherein the pre-paging configuration indicates a time and frequency resource assignment for pre-paging and a temporary UE ID, wherein the temporary UE ID corresponds to the first UE ID; and
monitor for the first UE ID in a pre-paging message.
14 . The apparatus of claim 13 , wherein to establish the first UE ID, the one or more processors are configured to cause the UE to:
receive the first UE ID; and
transmit a registration complete message.

16 . The apparatus of claim 13 , wherein the first UE ID is shorter in length than a 5G serving temporary mobile subscriber identity (S-TMSI) associated with a UE.
17 . The apparatus of claim 13 , wherein the one or more processors are further configured to cause the UE to transmit an indication of a UE capability to monitor pre-paging.
18 . An apparatus for wireless communication at a first network entity, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to cause the first network entity to:
receive a pre-paging configuration with a first user equipment (UE) identifier (ID) wherein the pre-paging configuration indicates a time and frequency resource assignment for pre-paging and a temporary UE ID as the first UE ID;
generate a mapping between the pre-paging configuration and a second UE ID associated with the first UE ID; and
transmit a request associated with paging with the second UE ID and the pre-paging configuration.
19 . The apparatus of claim 16 , wherein the time and frequency resource assignment and the temporary UE ID are associated with a setup time and a validity duration.
20 . The apparatus of claim 18 , wherein the request is a pre-paging request, and wherein to transmit the request, the one or more processors are configured to cause the first network entity to transmit the request based at least in part on an expiration of a timer that starts after a paging request.
21 . The apparatus of claim 18 , wherein to transmit the request, the one or more processors are configured to cause the first network entity to transmit the request in response to reception of a UE context release message.
