Systems and methods for time division duplex (TDD) synchronizing in distributed communication systems (DCSs) synchronize remote units operating with 5G signals by initially connecting these remote units to a 4G TDD source, and once the remote units are synchronized, switching back to a 5G TDD source. By using the downlink synchronization process of 4G instead of the normal synchronization process of 5G, the synchronization of the remote units using 5G is expedited. Further, the 5G receiver is not compressed or otherwise negatively impacted.

Systems and methods for time division duplex (TDD) synchronizing in distributed communication systems (DCSs)

A multi-band remote unit is disclosed. The multi-band remote unit includes a number of radio frequency (RF) front-end circuits configured to generate a number of downlink RF communications signals associated with a number of frequency bands based on a number of downlink digital communications signals, respectively. The multi-band remote unit also includes a digital interface circuit and a digital processing circuit. The digital interface circuit is configured to receive an encapsulated downlink digital communications signal and generate the downlink digital communications signals associated with the frequency bands based on the encapsulated downlink digital communications signal. The digital processing circuit is configured to digitally process the downlink digital communications signals before providing the downlink digital communications signals to the RF front-end circuits. As such, it may be possible to share the digital processing circuit among RF front-end circuits, thus helping to reduce cost and/or power consumption of the multi-band remote unit.
