A radio communication system includes a plurality of mobile stations and a base station for selecting a plurality of radio channels whose frequencies are different from each other to perform radio communication with the mobile stations. The base station includes a plurality of pairs of receivers and transmitters, arranged in correspondence with the radio channels, for performing radio communication with the mobile stations, a plurality of reception field detectors for detecting that field levels of received signals output from the receivers are higher than a predetermined level, a controller for issuing an instruction to switch a radio channel when detection outputs which are larger in number than channels used in the base station are simultaneously generated by the reception field detectors, and a channel switching controller for selecting one pair from the pairs of idle receivers and idle transmitters on the basis of the instruction from the controller to switch at least one of busy radio channels, thereby continuing communication.
