A base station receives a signal transmitted from a mobile station, estimates the state of the radio uplink, and receives state information indicating the state of the radio downlink measured by the mobile station. When the uplink quality and the downlink quality satisfy scheduling grant conditions set up in advance, the base station is allowed to carry out scheduling for the mobile station. In contrast, the base station is not allowed to carry out the scheduling for any terminal in which a link imbalance has occurred. Therefore, the throughput of the whole system increases.
