Question: What condition must be fulfilled for a UE to consider the entering condition for Event X2 (Serving L2 U2N Relay UE becomes worse than threshold) satisfied?
Option 1: The measurement result of the serving L2 U2N Relay UE minus the hysteresis parameter is greater than the threshold parameter.
Option 2: The measurement result of the serving L2 U2N Relay UE plus the hysteresis parameter is less than the threshold parameter.
Option 3: The measurement result of the serving L2 U2N Relay UE minus the hysteresis parameter is less than the threshold parameter.
Option 4: The measurement result of the serving L2 U2N Relay UE plus the hysteresis parameter is greater than the threshold parameter.
Explanation: According to the specification, Inequality X2-1 (Entering condition) states that Mr + Hys < Thresh. This means that for a UE to consider the entering condition for Event X2 satisfied, the measurement result of the serving L2 U2N Relay UE plus the hysteresis parameter must be less than the threshold parameter.
