Question: In a TDD network with a DRX cycle length of 1.28 seconds, what is the maximum allowed cell re-selection delay to ensure at least a 90% correct cell reselection rate with a 95% confidence level?
Option 1: 5 seconds
Option 2: 6.4 seconds (applicable to TDD only)
Option 3: Less than 8 seconds
Option 4: 10 seconds to account for additional network latency
Explanation: The correct answer balances efficient cell re-selection with DRX cycle lengths and system information reception times. Allowing less than 8 seconds accommodates TevaluateNTDD (implied by the context, not explicitly defined) and time for receiving system information, ensuring a high rate of correct cell reselections under specified confidence levels in TDD networks.
