Question: What is excluded from the measurement reporting delay in the event triggered reporting period for UEs supporting FDD and GSM when transmitting over the Uu interface?
Option 1: The time taken to process the measurement at the UE before transmission.
Option 2: Delays caused by other RRC signalling on the DCCH.
Option 3: A delay uncertainty resulting from inserting the report into the TTI of the uplink DCCH, equivalent to twice the TTI duration.
Option 4: The propagation time of the signal through the Uu interface.
Explanation: The measurement reporting delay excludes the uncertainty introduced by aligning the measurement report with the Transmission Time Interval (TTI) of the uplink Dedicated Control Channel (DCCH), specifically twice the TTI duration, to accurately measure the delay.
