Question: In a TDD (Time Division Duplex) radio resource management scenario, where two synchronized cells (Cell 1 and Cell 2) share the same frame and timeslot timing, what is the specified transmission timeslot for the Downlink Dedicated Physical Channel (DL DPCH) in this setup?
Option 1: Timeslot 8
Option 2: Timeslot 4
Option 3: Timeslot 10
Option 4: Timeslot 12
Explanation: In the context of managing radio resources in a TDD system, especially when testing synchronization and timing differences between cells, the precise allocation of timeslots for different channels is crucial. The Downlink Dedicated Physical Channel (DL DPCH) is designated for transmitting data from the base station to the User Equipment (UE). According to the specified setup, Timeslot 4 is allocated for the DL DPCH, ensuring efficient use of resources and minimizing interference between downlink and uplink transmissions, which are typically separated in TDD systems by using different timeslots (e.g., UL DPCH in Timeslot 12). This allocation facilitates the testing of SFN-SFN observed time difference type 1 measurement accuracy within the required limits.
