Question: In a TDD (Time Division Duplex) system with 3.84 Mcps, what is the defined reference point for measuring Cell Synchronisation Burst Timing in a Node B?
Option 1: The air interface between the Node B and User Equipment (UE)
Option 2: The Tx (Transmit) antenna connector of the neighbouring cell
Option 3: The midpoint between the Node B and the neighbouring cell
Option 4: The Rx (Receive) antenna connector of the Node B
Explanation: Accurate measurement of Cell Synchronisation Burst Timing is crucial for synchronization between cells in a TDD system. Measuring from the Rx (Receive) antenna connector of the Node B ensures that the timing is referenced at the point closest to where the signal is actually received, minimizing potential delays or inaccuracies introduced by the Node B’s internal processing or cabling. This precise measurement point is essential for maintaining synchronization across the network.
