Abstract

The present invention is designed to reduce the impact of interference even when different DL/UL configurations are applied between neighboring transmission points (radio base stations). A radio base station which can communicate with a user terminal by means of time division duplexing, and furthermore change and control the DL/UL configuration, has an interference measurement section that measures the interference level from other radio base stations in at least a UL subframe, and a scheduling control section that changes the feedback method of uplink control signals, which the user terminal feeds back in the UL subframe in response to downlink signals that have been transmitted in DL subframes, based on the measured interference level.
