Abstract: A method of operating a repeater comprises detecting a synchronization signal from a received communication signal, identifying a time division duplex (TDD) switching pattern based on a power change of the communication signal over time and switching an uplink operation and a downlink operation of the repeater based on the detected synchronization signal and the TDD switching pattern.

Abstract: A node unit of a distributed antenna system includes a power supply unit for supplying power for operating the node unit, a digital part operated by the power supplied from the power supply unit, the digital part performing digital processing on input relay signals and outputting the digital-processed relay signals, and a controller for disabling an output of the digital part in response to a first control command for instructing a reset of the power supply unit or a second control command for instructing a reset of the digital part.
