PURPOSE: An integrated base station device in a communication system is provided to cut additional base station installation costs dependent on an increase of capacity and increase call quality by integrating base stations, installed in many places, into one and offering service after sectionalizing many antennas through the integrated base station. CONSTITUTION: A BCP(BTS Control Processor)(10) processes the calls of large capacity at a high speed. A DU(Digital Unit)(20) processes the call-processed signals of large capacity by the channel. An RFU(Radio and Frequency Unit)(30) executes radio processing for the signals by sectors processed at the DU(20). A TFU(Time and Frequency Unit)(40) provides information on the time and frequency of a base station to the DU(20) and the RFU(30) respectively. An LPA(Linear Power Amplifier)(50) linearly amplifies the radio signals by sectors processed at the RFU(30). The first to the Nth delay unit(60-1-60-N) delay each of the power-amplified radio signals as much as a time difference, depending on the distance between a base station and an antenna. The first to the Nth antenna(Ant1-AntN) emit each of the delayed radio signals to the external.
