Question: In E-UTRA handover scenarios, what is the maximum allowed interruption time on the original cell during the initial handover period, and what is the subsequent action completion deadline for the UE to release the original cell after initiating handover to the target cell?
Option 1: 3ms interruption, complete release of Cell 1 within 30ms
Option 2: 6ms interruption, complete release of Cell 1 within 21ms
Option 3: 10ms interruption, complete release of Cell 1 within 15ms
Option 4: 12ms interruption, complete release of Cell 1 within 25ms
Explanation: During the initial handover period, the maximum allowed interruption on the original cell should not exceed 6ms. After initiating handover to the target cell, the UE must complete releasing the original cell within 21ms from the start of the relevant time period, ensuring seamless E-UTRA handovers.
