Question: In a scenario where a UE receives an MBMS service while monitoring neighboring cells on two carriers, what is the maximum allowed cell re-selection delay to ensure at least 90% correct cell reselections?
Option 1: Less than 480 ms
Option 2: Between 1.5 s and 2.5 s
Option 3: Less than 1.9 s
Option 4: Greater than 2.72 s
Explanation: This answer reflects the specified maximum cell re-selection delay for ensuring at least 90% correct cell reselections, balancing between timely handovers and reliable service continuity during MBMS reception and neighbor cell monitoring.
