Question: In a TDD (Time Division Duplex) system, what is the primary reference point for determining the time position of both the leading and lagging guard-periods of a burst under test, as well as the equivalent guard periods of the subsequent two bursts?
Option 1: The trailing edge of the previous frame
Option 2: The midamble of an adjacent burst in the same frame
Option 3: The start of the current Time Slot in Frame
Option 4: The time position of the midamble of the burst under test
Explanation: In TDD systems, precise timing is crucial for maintaining signal integrity and preventing interference. The midamble, being a central reference within a burst, serves as an optimal anchor point for synchronizing the timing of guard periods. This ensures accurate positioning of guard-periods relative to the midamble's time position, facilitating seamless transmission and reception in a TDD frame structure, which is crucial for effective UE communication with the base station.
