Question: What condition should be fulfilled for a UE to consider entering Event C1, related to the NR sidelink channel busy ratio being above a threshold?
Option 1: When the measurement result of channel busy ratio (Ms) is below the threshold parameter (Thresh) minus the hysteresis parameter (Hys).
Option 2: When the measurement result of channel busy ratio (Ms) equals the threshold parameter (Thresh) plus the hysteresis parameter (Hys).
Option 3: When the measurement result of channel busy ratio (Ms) is above the threshold parameter (Thresh) minus the hysteresis parameter (Hys).
Option 4: When the measurement result of channel busy ratio (Ms) equals the threshold parameter (Thresh) minus the hysteresis parameter (Hys).
Explanation: According to the 3GPP TS specification, Inequality C1-1 (Entering condition) states that the UE should consider entering Event C1 when Ms is above Thresh - Hys. This ensures that the event is triggered only when the channel busy ratio exceeds a certain threshold, taking into account hysteresis to prevent frequent triggering.
