Question: In the context of Event X2 for a Serving L2 U2N Relay UE, what condition must be met for the UE to consider leaving the event?
Option 1: Measurement result (Mr) equals the threshold (Thresh)
Option 2: Measurement result (Mr) minus hysteresis (Hys) is greater than the threshold (Thresh)
Option 3: Measurement result (Mr) plus hysteresis (Hys) is less than the threshold (Thresh)
Option 4: Measurement result (Mr) is equal to or greater than the threshold (Thresh) plus hysteresis (Hys)
Explanation: The leaving condition for Event X2 is satisfied when the measurement result (Mr) minus the hysteresis parameter (Hys) is greater than the threshold parameter (Thresh), i.e., Mr – Hys > Thresh, preventing immediate reversion due to minor fluctuations in measurement results.
