Question: In a TDD (Time Division Duplex) radio resource management test for SFN-CFN (System Frame Number - Cell Frame Number) observed time difference measurement accuracy, what is the specified transmission timeslot for the Uplink Dedicated Physical Channel (UL DPCH)?
Option 1: Timeslot 1
Option 2: Timeslot 3
Option 3: Timeslot 4
Option 4: Timeslot 2
Explanation: According to the test setup for verifying SFN-CFN observed time difference measurement accuracy in a synchronized cell environment, the Uplink Dedicated Physical Channel (UL DPCH) is specifically transmitted in timeslot 2. This detail is crucial for ensuring accurate measurements of timing differences between cells, which can range from 0 to 256 frames in this test scenario. The correct identification of UL DPCH's timeslot highlights understanding of the test's technical requirements for assessing radio resource management capabilities in TDD systems.
