Question: What is excluded from the measurement reporting delay in Event Triggered Reporting for Radio Resource Management in TDD?
Option 1: The time taken for UE to process the measurement before transmission
Option 2: A delay caused by lack of uplink resources for the UE to send the report, and a delay uncertainty when inserting the report into the TTI of the uplink DCCH
Option 3: The RRC signalling delay on the DCCH and the L3 filtering processing time
Option 4: The transmission time of the measurement report over the air interface
Explanation: According to specifications, the measurement reporting delay excludes two types of delays: (1) a delay due to no available uplink resources for sending the report, and (2) a delay uncertainty from inserting the report into the Transmission Time Interval of the uplink Dedicated Control Channel. This distinguishes between different sources of delay in radio resource management for accurate performance assessment and optimization.
