Abstract:
1. A base station in a radio communication system in which a plurality of base stations communicate with a terminal using one or more of a plurality of time slot patterns which have slots divided in time and transmission timing of the slots has a certain interval, the base station comprising: an interference measurement unit that measures an uplink interference power in each time slot pattern within at least the interval; a time slot pattern determination unit that determines a time slot pattern in which measured uplink interference power is a minimum or smaller than a predetermined threshold value as an uplink time slot pattern to be used in an uplink communication, and a time slot pattern of timing shifted from the determined uplink time slot pattern by a predetermined timing as a downlink time slot pattern to be used in a downlink communication; and a communication processing unit that communicates with the terminal using determined uplink and downlink time slot patterns, wherein the interference measurement unit stops an uplink communication of a first terminal that communicates with the base station, and measures the uplink interference power from one or more second terminals belonging to another one of the base stations.
