Time Division Duplexing (TDD)

Time Division Duplexing (TDD) is a technique to emulate full-duplex communication over a half-duplex communication link by transmitting the downlink (DL) and receiving the uplink (UL) at the same frequency but using synchronized time intervals. The UL and DL are separated by a guard period to avoid overlapping of the communication channels. Due to advanced technology, the switching is done within milliseconds and therefore fast enough for low latency 5G scenarios. The advantage of this technique is that it excels in spectral efficiency and can deliver improved latency results. To learn more, read our blog ‘RF and 5G new radio: top 5 questions answered’.
