Question: In an NE-DC scenario, a User Equipment (UE) experiences a Secondary Cell Group (SCG) failure due to repeated transmission failures. How should the UE categorize this failure?
Option 1: rlc-MaxNumRetx (Maximum Number of RLC Retransmissions reached)
Option 2: t313-Expiry (Timer T313 Expiration)
Option 3: randomAccessProblem (Random Access Problem detected by SCG MAC)
Option 4: scg-ChangeFailure (SCG Change Failure)
Explanation: This is because the failure scenario described involves 'repeated transmission failures', which aligns with the condition of reaching the maximum number of retransmissions at the Radio Link Control (RLC) layer, prompting the UE to consider the failureType as rlc-MaxNumRetx. This categorization is crucial for appropriate error handling and recovery procedures in NE-DC operations.
