PURPOSE: A transmission/reception operation control method, a digital unit supporting the same and a separated base station capable of controlling transmission/reception operation according to channel wideband applied a remote RF unit. CONSTITUTION: A DU(Digital Unit) periodically monitors a connection state with an RRU(Remote Radio Frequency Unit)(S502). If the digital unit receives channel bandwidth information, the channel bandwidth information is confirmed. Synchronization signal is generated by an oscillation frequency adjustment(S506). The clock based on the synchronizing signal is generated(S508). The transmission/reception operation is controlled in order to the modulation/demodulation process of IQ signal(S510).
