Question: What is the maximum allowed measurement reporting delay for a UE to send an Event triggered measurement report for an E-UTRA FDD cell (e.g., Cell3) from the beginning of time period T2?
Option 1: Less than 5 seconds
Option 2: Less than 4270 milliseconds
Option 3: Less than 10 seconds
Option 4: Less than 2000 milliseconds
Explanation: This question assesses understanding of specific timing requirements for measurement reporting in E-UTRA FDD cells. The correct answer, "Less than 4270 milliseconds", reflects the precise delay specified for Event triggered reports in E-UTRA FDD cells (e.g., Cell3) from the start of time period T2. This highlights the importance of timely measurement reporting for efficient network operation and handover decisions. Incorrect options (1, 3, and 4) either confuse the delay with that of inter-frequency UTRA TDD cells or propose arbitrary values not aligned with the specification.
