Question: In the context of Event A5H2 for a UE (User Equipment) in an NR (New Radio) network, what triggers the leaving condition for this event, considering the conditions defined by 3GPP specifications?
Option 1: Only when the serving cell's (SpCell) measurement result (`Mp`) exceeds `Thresh1` without hysteresis (`Hys1`).
Option 2: Exclusively if the neighbouring cell's measurement result (`Mn`) plus offsets falls below `Thresh2` with hysteresis (`Hys1`).
Option 3: Solely when the UE's aerial altitude (`Ms`) surpasses `Thresh3` without considering hysteresis (`Hys2`).
Option 4: When at least one of the following conditions is met: `Mp - Hys1 > Thresh1`, `Mn + Ofn + Ocn + Hys1 < Thresh2`, or `Ms - Hys2 > Thresh3`.
Explanation: According to the specifications for Event A5H2, the leaving condition is satisfied when at least one of the three specified conditions (A5H2-4, A5H2-5, or A5H2-6) is fulfilled. This means any of the conditions related to the serving cell's measurement result improving past a threshold, the neighbouring cell's combined measurement falling below a threshold, or the UE's altitude increasing beyond a set threshold (all with their respective hysteresis considerations), will trigger the leaving condition. Thus, Option 4 accurately reflects this requirement by encompassing all three conditions.
