Abstract: An operating method of a repeater, the operating method comprises: receiving a first communication signal according to a first mobile communication standard, generating a time division duplex (TDD) switching signal based on information about a start point of the received first communication signal, and controlling switching of an uplink and a downlink of a repeater that relays a second communication signal according to a second mobile communication standard based on the generated TDD switching signal.

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.
