Question: In a 3GPP-compliant TDD (3.84 Mcps option) network, what is excluded from the measurement reporting delay during an event-triggered reporting period for a User Equipment (UE)?
Option 1: Propagation delay between UE and the nearest eNodeB
Option 2: Time taken for RRC signaling on the DCCH to prioritize reports
Option 3: The time required for UE to switch from idle to active transmission mode
Option 4: Delay uncertainty due to inserting reports into the TTI of the uplink DCCH
Explanation: According to the specifications, the measurement reporting delay in an event-triggered reporting period for a UE does not include the delay uncertainty that occurs when fitting the measurement report into the Transmission Time Interval (TTI) of the uplink Dedicated Control Channel (DCCH). This specific exclusion highlights the differentiation between the inherent reporting latency and the variability introduced by the TTI alignment, which is twice the TTI duration in this context.
