Question: In 3GPP-compliant TDD networks, what is excluded from the measurement reporting delay in event-triggered reporting for a User Equipment (UE) transmitting over the Uu interface?
Option 1: Propagation delay between UE and the nearest eNodeB
Option 2: Time taken for RRC signaling on the DCCH to clear the buffer
Option 3: The time required for UE to switch from idle to active state
Option 4: Delay uncertainty due to inserting reports into the TTI of the uplink DCCH
Explanation: The measurement reporting delay in event-triggered reporting for a UE does not include the delay uncertainty when fitting the measurement report into the Transmission Time Interval (TTI) of the uplink Dedicated Control Channel (DCCH), clarifying how the delay is defined and measured.
