Question: In a UTRA 1.28 Mcps TDD scenario, what is the primary factor that the cell search delay requirement assumes is NOT impacting the timing of the event-triggered measurement report sent by the UE?
Option 1: Congestion in the uplink shared channel (UL-SCH)
Option 2: Interference from neighboring cells on the downlink shared channel (DL-SCH)
Option 3: Delay caused by other Radio Resource Control (RRC) signalling on the Dedicated Control Channel (DCCH)
Option 4: The UE's processing power and memory capacity
Explanation: The cell search delay requirement specifically isolates the measurement of interest by assuming that the timing of the event-triggered measurement report is not influenced by concurrent RRC signalling on the DCCH. This focuses the requirement on the inherent capabilities of the UE in detecting and reporting cell-related events, without the confounding factor of potential delays introduced by other control channel activities.
