Embodiments of the disclosure relate to downlink (DL) and uplink (UL) communication path switching in a time-division duplex (TDD) distributed antenna system (DAS). In this regard, a communications control circuit is provided. The communications control circuit is configured to synchronize to DL periods and UL periods of TDD communication signal to switch a TDD communication signal between a DL communication path and a UL communication path in a DAS accordingly. The communication control circuit is configured to detect the DL periods and/or the UL periods in the TDD communication signal by sensing a power increase associated with the TDD communication signal in the DL communication path. In this manner, the TDD communication signals can be synchronously directed to the DL communication path and UL communication path without destructing and/or decoding the TDD communication signals.
