Abstract
Provided is a wireless base station which uses distributed antennas and selects a combination of a plurality of wireless terminals and the distributed antennas of a wireless base station that performs multi-user transmission with respect to the plurality of wireless terminals in a multi-BSS wireless environment. The wireless base station includes: a scheduling unit that measures reception power (RSSI) from each wireless terminal at each of the distributed antennas and selects a combination of a plurality of wireless terminals and a plurality of antennas having approximately the same RSSIs in descending order for respective wireless terminals; and a transmission power control unit that sets minimum transmission power corresponding to the RSSI of the antenna when multi-user transmission is performed between the plurality of wireless terminals and the plurality of antennas combined by the scheduling unit.
