Title: WIRELESS BASE STATION, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD
Abstract:
In order to reduce the effect of inter-cell interference by interference control using signaling between wireless base stations, a wireless base station in a wireless communication system according to the present invention: uses a UL/DL configuration, which expresses a configuration for UL sub-frames and DL sub-frames within a wireless frame, to wirelessly communicate with a user terminal; determines interference-control information, which is used in interference control, for fixed sub-frames and flexible sub-frames in the UL/DL configuration; and transmits the interference control information to a neighboring wireless base station via an interface between the wireless base stations.
