Question: What is excluded from the measurement reporting delay in event-triggered reporting for E-UTRAN TDD, as per 3GPP specifications?
Option 1: The time taken for UE to process the measurement before transmission
Option 2: A delay caused by other RRC signalling on the DCCH and a delay uncertainty due to TTI of uplink DCCH insertion
Option 3: Only a delay resulting from no available UL resources for the UE to send the report
Option 4: Both a delay uncertainty resulted from inserting the report into the TTI of the uplink DCCH and a delay caused by lack of UL resources for the UE
Explanation: According to the specifications, two types of delays are explicitly excluded from the measurement reporting delay: 1. Delay uncertainty when inserting the measurement report into the Transmission Time Interval (TTI) of the uplink Dedicated Control Channel (DCCH). 2. A delay caused by the absence of uplink (UL) resources for the User Equipment (UE) to send the measurement report. Therefore, the correct answer includes both exclusions, making Option 4 the accurate choice.
