Abstract:
The present invention is designed to control inter-cell interference adequately even when a plurality of cells are placed at a high density. A user terminal can connect with a plurality of radio base stations, and has a receiving section that receives a downlink signal from each radio base station, and a power control section that, when an uplink grant or a downlink assignment and a control signal for power control are detected at the same time from the downlink signal, prioritizes a TPC command contained in the control signal for power control, and changes transmission power.
