Abstract
In radio communication, the invention delivers a transmission signal wave from a transmission station to a plurality of receiving stations whereby the signal wave places the station in communication with the receiving stations using the same carrier passage reciprocally. The transmission station can determine the service condition of the carrier passage on the space in which communication takes place so that generation of the carrier wave which interferes with the station in the midst of communication can be prevented. There is a signal wave transmitter for transmitting specified signal waves from the other station at intervals shorter than the transmission intervals of the response signals. There is a monitor for monitoring whether the interference wave exists in the carrier passage on the space in which the delivery of the waves is about to be performed when an optional station of the radio communication stations begins to deliver the transmission wave or transmit the signal wave. There is a controller for judging and controlling whether delivery or transmission of the transmission wave from the optional station or transmission of the signal wave should be started when the monitor judges that an interference wave exists.
