Question: Upon receiving N311 consecutive 'in-sync' indications for the Secondary Cell (SpCell) while T310 timer is running, what actions does the User Equipment (UE) take regarding its timers for the corresponding SpCell?
Option 1: Only stop timer T310 for the corresponding SpCell.
Option 2: Stop both timer T310 and timer T312 (if running) for the corresponding SpCell.
Option 3: Start timer T312 if it's not already running, in addition to stopping timer T310.
Option 4: Ignore 'in-sync' indications until T310 expires naturally.
Explanation: According to the specified behavior for recovering from physical layer problems, upon receiving N311 consecutive 'in-sync' indications while T310 is running, the UE must stop both the T310 timer and the T312 timer if it is currently running. This ensures that once the UE regains synchronization with the SpCell, it promptly ceases any ongoing error recovery timers related to that cell, maintaining the RRC connection without needing explicit signaling.
