Claim Text:
1. A communication duration configuring method in a mobile communication system with a relay station for relaying wireless communications between a base station and a mobile station, the method comprising: configuring a communication duration that is at least one of a downlink communication duration in which the relay station receives a transmission signal from the base station while limiting a transmission of a signal from the relay station to the mobile station, and an uplink communication duration in which the relay station transmits the transmission signal to the base station while limiting a transmission of a signal from the mobile station to the relay station; measuring a self-interference amount in the relay station; and controlling a configuration of the communication duration, wherein the communication duration is configured by configuring, by the relay station, a subframe at a predetermined position in one radio frame when the self-interference amount is larger than a reference value, and a subframe is not configured in one radio frame when the self-interference amount is equal to or less than the reference value, and the reference value is determined according to a self-interference mitigation capability of the relay station.
