Question: In a TDD (Time Division Duplex) scenario, what is the maximum allowed time for a User Equipment (UE) to complete cell re-selection, from the start of the T2 period to sending an RRC CONNECTION REQUEST on the new cell?
Option 1: Less than 8 seconds
Option 2: Exactly 10 seconds
Option 3: More than 12 seconds
Option 4: Up to 15 seconds
Explanation: The correct answer is based on the understanding of cell re-selection delay in TDD mode, where the UE needs to quickly adapt to a new cell for seamless connectivity. The specified maximum time of less than 8 seconds ensures efficient handover, maintaining service continuity and user experience. This timeframe accounts for the evaluation period (TevaluateNTDD) plus the time to receive system information (TSI), aligning with typical radio resource management (RRM) requirements in telecom networks.
