COMMUNICATION DURATION CONFIGURING METHOD, RELAY STATION, BASE STATION, AND MOBILE COMMUNICATION SYSTEM
First Claim
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 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 according to the self-interference amount.
