Question: In a TDD (Time Division Duplex) system, when applying a signalled Timing Advance value to UL (Uplink) DPCH (Dedicated Physical Channel) transmission timing, what is the required accuracy for the Timing Advance adjustment?
Option 1: ±1 chip
Option 2: ±0.25 chip
Option 3: ±1.5 chips
Option 4: ±0.5 chip
Explanation: The correct answer is Option 4 because, according to the specified requirements for Timing Advance adjustment in TDD systems, the accuracy must be within ±0.5 chip to ensure proper synchronization and minimize errors in uplink transmissions. This level of precision is crucial for maintaining the integrity of the signal and overall network performance.
