Question: Upon selecting a new L2 U2N Relay UE while timer T311 is running, what action does the L2 U2N Remote UE take regarding its cell selection procedure?
Option 1: Continue the cell selection procedure to evaluate additional options.
Option 2: Stop the cell selection procedure, if ongoing.
Option 3: Suspend the cell selection procedure until T301 expires.
Option 4: Initiate a new cell selection procedure targeting only relay UEs.
Explanation: When a suitable L2 U2N Relay UE is selected during an ongoing T311 timer, the Remote UE's immediate response includes halting any concurrent cell selection process. This ensures resources are reallocated towards establishing communication with the newly selected relay, streamlining the connection setup and minimizing delays in the sidelink relay adaptation protocol (SRAP) establishment. Stopping the cell selection procedure upon selecting a new relay optimizes network resource utilization and focuses on securing a stable link via the chosen relay.
