Question: What condition must be fulfilled for a UE to consider the entering condition for Event S1 (Serving becomes better than threshold) satisfied?
Option 1: The NR sidelink measurement result minus the hysteresis parameter is greater than the threshold parameter.
Option 2: The NR sidelink measurement result plus the hysteresis parameter is less than the threshold parameter.
Option 3: The NR sidelink measurement result equals the threshold parameter.
Option 4: The hysteresis parameter is greater than the threshold parameter.
Explanation: According to the 3GPP specification, Inequality S1-1 (Entering condition) states that Ms – Hys > Thresh must be fulfilled for the entering condition of Event S1 to be satisfied. This means that the UE considers the entering condition satisfied when the NR sidelink measurement result minus the hysteresis parameter is greater than the threshold parameter.
