Question: For 3.84Mcps TDD cell synchronization bursts in the steady-state phase, what are the possible triggering conditions for sending measurement reports via Synchronisation Report Characteristics IE on the UTRAN Iub interface?
Option 1: Only when the requested threshold is exceeded or after every SFN period.
Option 2: After every measured frame, but only if a certain quality metric is met.
Option 3: After every measured frame, after every SFN period, after every cycle length, or only when the requested threshold is exceeded.
Option 4: Immediately after the first measured frame and then only after every cycle length.
Explanation: In the steady-state phase for 3.84Mcps TDD cell synchronization bursts, the Synchronisation Report Characteristics IE allows flexibility in when measurement reports are sent. This can be based on regular intervals (every measured frame, SFN period, or cycle length) or conditionally when a specific threshold is exceeded, ensuring efficient use of resources while maintaining necessary monitoring levels.
