Question: In E-UTRA, for Event A3 triggered measurement reports, what is the maximum allowed measurement reporting delay from the start of time period T2, considering additional uncertainties?
Option 1: Less than 1.6 s
Option 2: Less than 3.2 s (without considering additional uncertainties)
Option 3: Up to 6.4 s (accounting for up to 2xTTI insertion uncertainty in DCCH)
Option 4: Greater than 8 s
Explanation: The correct answer accounts for the base delay of less than 3.2 seconds from the start of T2, plus additional uncertainty due to TTI insertion in DCCH, potentially doubling the base delay, making up to 6.4 s the most accurate choice when considering real-world uncertainties.
