To solve the problem wherein in two mutual radio frequency bands acting as an intermediary of communication in time-division duplex operation, when transmitting and receiving timings of radio mobile stations become match between adjacent mutual frequency bands because radio waves transmitting and receiving timings of the mobile stations have been out of synchronization with each other, radio wave interference that should not have essentially been received might be given to a base station for receiving radio waves within one side adjacent frequency band from a mobile station for transmitting radio waves within an arbitrary frequency band; and at the same time, radio wave interference that should not have essentially been received might be given to a base station for receiving the radio waves within the other side adjacent frequency band from the mobile stations for transmitting the radio waves within an arbitrary frequency band.

In the radio wave transmission and reception method, the radio wave transmitting and receiving timings of the mobile stations are mutually reversed for the adjacent frequency bands.
