During the course of research, I have found a really hard time understanding this short lines below. I will appreciate a short hint or explanation from any expert in this area.
Time division duplex (TDD) concerns at least a 2 way communication. For example, a discussion is taking place between two people, say a and b, a talks whilst b listens, then b talks whilst a listens. A and b can't talk at the same time, hence timely divided and both share a time unit. Full duplex can be imagined as if both a and b talk and listen at the same time which double the amount of the information exchanged. Hope this helps.
