Abstract: In a radio communication system a first radio station performs communication by the use of a first radio signal. A second radio station receives a second radio signal which is indistinguishable from the first radio signal. A third radio station is in a radio communication area of the first radio station and a radio communication area of the second radio station. A communication format conversion unit generates a third radio signal by converting a communication format of the second radio signal to a communication format which is distinguishable from the first radio signal, and communicates with the third radio station by the use of the third radio signal.

Abstract: Each of two or more base stations notifies a communication controller of information on a first frequency band that the base station uses for radio communication. Based on the information on the first frequency bands acquired from the two or more base stations, the communication controller selects a second frequency band to be used by the two or more base stations to transmit the data with common content, and notifies the two or more base stations of information on the selected second frequency band. The two or more base stations transmit the data with common content based on the information on the second frequency band acquired from the communication controller.
