Question: What is the required accuracy for a User Equipment (UE) to adjust its transmission timing in relation to the signalled timing advance value in TDD mode?
Option 1: ±1 chip
Option 2: ±0.25 chip
Option 3: ±0.5 chip
Option 4: ±2 chips
Explanation: In TDD (Time Division Duplex) mode, precise timing adjustment is crucial for effective communication. The UE must synchronize its transmissions with the base station's expectations, as defined by the signalled timing advance value. An accuracy of ±0.5 chip ensures that the UE's transmissions are closely aligned with the expected timing, minimizing potential interference and maximizing network efficiency. This level of precision is critical for maintaining high-quality service in wireless communications, especially in environments where timing misalignments could lead to significant signal degradation.
