1. An apparatus that operates a small cell, the apparatus comprising:processing circuitry configured to
cut a number of beams used for downlink transmission on resources;
concentrate a transmission power on the resources so as to improve a downlink quality of a unit frequency band used in the small cell; and
report information for computing an improved downlink quality, the information being reported to a terminal that connects to the small cell, and the information indicating a difference between an antenna gain of a reference signal and a maximum antenna gain.
