Abstract:
1. A wireless communication base station used as a first base station in a wireless communication system including the first base station having a relatively large allowable arrival range of a downlink transmit power to a user equipment, and a second base station having a relatively small allowable arrival range of the downlink transmit power to a user terminal, and affected with an interference by an uplink communication of the first base station and the user terminal, the wireless communication base station comprising: a communication prohibited period setting unit configured to set an uplink communication prohibited period to the user equipment belonging to the wireless communication base station per se, wherein the uplink communication from the user equipment to the wireless communication base station per se is prohibited during the uplink communication prohibited period; a grouping processing unit configured to divide user terminals belonging to the wireless communication base station per se into a plurality of groups, and set an uplink communication time period to different time periods of the respective groups; and an information collecting unit configured to collect a piece of information indicating magnitudes of interferences affecting the second base station by the uplink communication from the user equipment, wherein the grouping processing unit is configured to make the user terminal in which the magnitude of the interferences affecting the second base station exceeds a previously determined criterion belong to a group the same as a group of the second base station.
