Question: In a TDD conformance test, after the UE receives a MEASUREMENT CONTROL message, what triggers the transmission of a MEASUREMENT REPORT message with event 1I for cell 1 in timeslot 2, and within what timeframe must this report be sent after a power setting change?
Option 1: The UE's internal timer expires; the report must be sent within 200 ms after the power settings switch from T1 to T2.
Option 2: The UE detects a significant change in downlink power; the report must be sent within 480 ms after the power settings switch from T1 to T2.
Option 3: The SS switches the power settings from T1 to T2; the report must be sent within 480 ms after this switch, triggered by event 1I for cell 1 in timeslot 2.
Option 4: The UE completes its internal self-test; the report must be sent within 1000 ms after the power settings switch from T1 to T2.
Explanation: This question assesses understanding of the test procedure for UE conformance in a TDD environment, specifically the triggers and timing for measurement reporting. Option 3 correctly identifies that the transmission of the MEASUREMENT REPORT message with event 1I is triggered by the SS switching power settings from T1 to T2, and this report must be sent within 480 ms after this switch, as outlined in step 5 and 6 of the procedure. This requires knowledge of how UE measurement reporting is controlled and timed in response to network changes in a test scenario.
