1. A relay station that is shared among a plurality of operators and that relays signals communicated between base stations and mobile stations of the plurality of operators, the relay station comprising:

  • a band allocation determining section that calculates a difference between a first throughput and a second throughput for each of the plurality of operators, the first throughput being a throughput for communication between the base station and the mobile station via at least the relay station, and the second throughput being a throughput for communication between the base station and the mobile station without using the relay station, and determines a bandwidth for each of the operators in a shared band so as to maximize a product of the respective differences for the respective operators, the shared band being a band used between the relay station and the mobile stations and being shared among the plurality of operators; and

    a signal generation section that generates signals of the plurality of operators based on the bandwidths for the respective operators in the shared band.
