Question: In the context of 3GPP NR RRC, for Event A5 (SpCell becomes worse than threshold1 and neighbour becomes better than threshold2), what is the condition for the UE to consider leaving this event when both inequalities A5-3 and A5-4 are evaluated?
Option 1: Both Mp - Hys > Thresh1 AND Mn + Ofn + Ocn + Hys < Thresh2 must be true.
Option 2: Either Mp - Hys > Thresh1 OR Mn + Ofn + Ocn + Hys < Thresh2 (or both) needs to be fulfilled.
Option 3: Neither Mp - Hys > Thresh1 nor Mn + Ofn + Ocn + Hys < Thresh2 can be true.
Option 4: The UE must always satisfy Mp - Hys > Thresh1 before evaluating Mn + Ofn + Ocn + Hys < Thresh2.
Explanation: According to the specifications for Event A5, the leaving condition is satisfied when either condition A5-3 (Mp - Hys > Thresh1) OR condition A5-4 (Mn + Ofn + Ocn + Hys < Thresh2), or both, are fulfilled. This ensures flexibility in determining when to leave the event based on improvements in either the serving cell's measurement (Mp) or the neighbouring cell's comparative advantage (Mn with offsets).
