Question: What condition must be fulfilled for a UE to consider the entering condition for Event S2 (Serving becomes worse than threshold) satisfied?
Option 1: Ms + Hys > Thresh
Option 2: Ms - Hys < Thresh
Option 3: Ms = Thresh
Option 4: Ms + Hys < Thresh
Explanation: According to the specification, Inequality S2-1 (Entering condition) is fulfilled when Ms + Hys < Thresh. This means that for a UE to consider the entering condition for Event S2 satisfied, the sum of the NR sidelink measurement result (Ms) and the hysteresis parameter (Hys) must be less than the threshold parameter (Thresh).
