RADIO BASE STATION, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD

摘要

The present invention is designed to reduce the impact of inter-cell interference by interference control using signaling between radio base stations. In the radio communication system of the present invention, a radio base station carries out radio communication with a user terminal by using a UL/DL configuration, which represent the configuration of uplink subframes and downlink subframes in a radio frame. Also, the radio base station determines the interference control information to use in interference control in the fixed subframe and the flexible subframe in the above UL/DL configuration. Also, the radio base station transmits the above interference control information to the neighboring radio base stations via an inter-radio-base-station interface.

主权项

1. A radio base station that is connected to a neighboring radio base station via an inter-radio-base-station interface, comprising:
a radio communication section that carries out radio communication with a user terminal by using a UL/DL configuration, which represents a configuration of an uplink subframe and a downlink subframe in a radio frame; a determining section that determines interference control to information that is used in interference control for a fixed subframe and a flexible subframe in the UL/DL configuration; and an interface section that transmits the interference control information to the neighboring radio base station via the inter-radio-base-station interface.
