Question: In a 5G NR (New Radio) network, what condition must be met for a User Equipment (UE) to consider leaving Event S2, where 'Serving becomes worse than threshold' in the context of sidelink measurements?
Option 1: The measured sidelink power (Ms) minus the hysteresis value (Hys) is greater than the defined threshold (Thresh), i.e., Ms - Hys > Thresh.
Option 2: The measured sidelink power (Ms) plus the hysteresis value (Hys) is less than the defined threshold (Thresh), i.e., Ms + Hys < Thresh.
Option 3: The measured sidelink power (Ms) equals the defined threshold (Thresh) without considering the hysteresis value (Hys), i.e., Ms = Thresh.
Option 4: The measured sidelink power (Ms) plus the hysteresis value (Hys) equals the defined threshold (Thresh), i.e., Ms + Hys = Thresh.
Explanation: According to specifications for Event S2 in NR sidelink measurements, a UE considers leaving this event when Ms - Hys > Thresh. This indicates the measured sidelink power must significantly improve beyond just crossing the threshold, by at least the hysteresis value, ensuring stability in state transitions.
