Question: In the context of Event Y1 (PCell becomes worse than threshold1 and candidate L2 U2N Relay UE becomes better than threshold2), what condition must be met for the UE to consider leaving this event, based on the inequalities provided?
Option 1: Both Mp - Hys > Thresh1 and Mr + Hys < Thresh2 must be fulfilled simultaneously.
Option 2: Either Mp - Hys ≤ Thresh1 or Mr + Hys ≥ Thresh2 is sufficient.
Option 3: At least one of the conditions, either Mp - Hys > Thresh1 (Leaving condition 1) or Mr + Hys < Thresh2 (Leaving condition 2), must be fulfilled.
Option 4: The UE's measurement result for PCell (Mp) must exceed the threshold for the candidate L2 U2N Relay UE (Thresh2).
Explanation: According to the specifications for Event Y1, the leaving condition is satisfied when at least one of two conditions is met: either the measurement result of the PCell (Mp) minus hysteresis (Hys) is greater than threshold1 (Thresh1), or the measurement result of the candidate L2 U2N Relay UE (Mr) plus hysteresis (Hys) is less than threshold2 (Thresh2). This ensures a flexible trigger for exiting the event based on improvements in either the PCell's condition or the relay UE's condition relative to their respective thresholds, with consideration for hysteresis to prevent rapid toggling.
