Relay station, base station, and band frequency allocation method
First Claim
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.

Abstract
A relay station to which network sharing is applied, wherein it is possible to appropriately allocate between multiple operators a shared band frequency shared by the multiple operators, and to improve the frequency use efficiency. In a relay station (100), a band frequency allocation determination unit (107) determines the bandwidth for each operator within a shared band frequency, which is shared by multiple operators and used between the relay station (100) and a mobile station, on the basis of the quality of a first line between the relay station (100) and the base stations of the operators and on the basis of the status of a second line between the relay station (100) and the mobile stations of the operators. A signal generation unit (108) allocates the signal of the operators to a resource on the basis of the bandwidth for each operator in the shared band frequency.
