Question: In the context of Event A3H1 (Neighbour becomes offset better than SpCell and the Aerial UE altitude becomes higher than a threshold), what triggers the UE to consider the leaving condition for this event satisfied?
Option 1: When both conditions A3H1-3 and A3H1-4 are simultaneously fulfilled.
Option 2: When either condition A3H1-1 or condition A3H1-2 is no longer met.
Option 3: When at least one of the conditions A3H1-3 (neighbour cell measurement drops below a certain threshold) or A3H1-4 (Aerial UE altitude becomes lower than a specified threshold plus hysteresis) is fulfilled.
Option 4: When the SpCell's measurement result (Mp) exceeds that of the neighbouring cell (Mn) by more than the offset (Off).
Explanation: According to specifications for Event A3H1, the leaving condition is satisfied when either condition A3H1-3 (neighbour cell becomes less favourable after considering hysteresis) or condition A3H1-4 (Aerial UE altitude drops below a threshold plus hysteresis) is met, providing a nuanced trigger for exiting the event state based on changes in neighbour cell quality or UE altitude.
