Question: What is the required timing for a User Equipment (UE) to apply a signalled Timing Advance value to its transmission timing after receiving a timing advance command?
Option 1: Immediately upon reception of the timing advance command
Option 2: k slots before the designated activation time
Option 3: At the same slot as the reception of the timing advance command
Option 4: k+1 slots after the reception of the timing advance command
Explanation: This question assesses understanding of Timing Advance (TA) procedures in 5G NR, specifically how a UE adjusts its transmission timing. The correct answer reflects the standardized behavior where the UE applies the TA value at a designated time following the command receipt, ensuring synchronization with the base station (gNB), crucial for optimal radio resource management and minimizing interference.
