Question: What condition must be fulfilled for a UE to consider the entering condition for Event X1 (Serving L2 U2N Relay UE becomes worse than threshold1 and NR Cell becomes better than threshold2) satisfied?
Option 1: Both Inequality X1-1 (Mr + Hys < Thresh1) and Inequality X1-2 (Mn + Ofn + Ocn – Hys > Thresh2) must be fulfilled.
Option 2: Either Inequality X1-1 (Mr + Hys < Thresh1) or Inequality X1-2 (Mn + Ofn + Ocn – Hys > Thresh2) must be fulfilled.
Option 3: Only Inequality X1-1 (Mr + Hys < Thresh1) must be fulfilled.
Option 4: Only Inequality X1-2 (Mn + Ofn + Ocn – Hys > Thresh2) must be fulfilled.
Explanation: According to the specification, the UE shall consider the entering condition for Event X1 satisfied when both conditions X1-1 and X1-2 are fulfilled. This means that both inequalities (Mr + Hys < Thresh1 and Mn + Ofn + Ocn – Hys > Thresh2) must be true simultaneously.
