Question: In accordance with 3GPP RRC protocol for NR, what triggers the leaving condition for Event H1 (Aerial UE altitude becomes higher than a threshold)?
Option 1: The Aerial UE's altitude (Ms) exceeds the threshold value (Thresh) by more than the hysteresis parameter (Hys)
Option 2: The Aerial UE's altitude (Ms) plus the hysteresis parameter (Hys) becomes less than the threshold value (Thresh)
Option 3: The difference between the Aerial UE's altitude (Ms) and the threshold value (Thresh) equals the hysteresis parameter (Hys)
Option 4: The Aerial UE's altitude (Ms) alone drops below the threshold value (Thresh) without considering Hys
Explanation: According to the specifications for Event H1, the leaving condition is satisfied when the sum of the Aerial UE's current altitude and the hysteresis parameter is less than the defined threshold value, ensuring a buffer zone to prevent rapid triggering between entering and leaving conditions.
