Question: In RRC_IDLE, what information does a UE include in `sl-PagingIdentityRemoteUE` when it has paging related information to provide that hasn’t been sent before?
Option 1: Only ng-5G-S-TMSI
Option 2: Both ng-5G-S-TMSI and fullI-RNTI
Option 3: Either ng-5G-S-TMSI or fullI-RNTI, depending on UE configuration
Option 4: Neither ng-5G-S-TMSI nor fullI-RNTI; instead, it includes a temporary ID
Explanation: According to the specifications for RRC_IDLE state, when a UE has paging related information to provide (e.g., not sent `sl-PagingInfo-RemoteUE` before), it includes `ng-5G-S-TMSI` in the `sl-PagingIdentityRemoteUE`. This is specific to the RRC_IDLE state; the inclusion of both `ng-5G-S-TMSI` and `fullI-RNTI` is relevant for the RRC_INACTIVE state. Thus, in RRC_IDLE, only `ng-5G-S-TMSI` is included.
