Radio communication system, high-power base station, low-power base station, and communication control method

A base station used in a radio communication system, comprising:

• a processor configured to set normal subframes and specific subframes among a plurality of subframes used for a downlink, wherein a transmission power of the specific subframes is limited to low compared with the normal subframes, and
• the processor changes a setting pattern of the normal subframes and the specific subframes among the plurality of subframes on the basis of information on a load of other base station, wherein the information on the load of the second base station is acquired via an X2 interface and indicates a usage rate of resource blocks in the second base station.
