Question: What is excluded from the measurement reporting delay in the event triggered reporting period for UEs (User Equipment) in FDD (Frequency Division Duplex) mode?
Option 1: Delay uncertainty due to TTI (Transmission Time Interval) of the uplink DCCH (Dedicated Control Channel)
Option 2: Time taken for RRC (Radio Resource Control) signalling on the DCCH
Option 3: Processing time at the UE before initiating transmission over the Uu interface
Option 4: Propagation delay between the UE and the base station
Explanation: The excluded delay relates to uncertainty introduced when inserting the measurement report into the Transmission Time Interval (TTI) of the uplink Dedicated Control Channel (DCCH), specifically quantified as twice the TTI, highlighting its relation to the TTI timing structure.
