Abstract
In a base station, a downlink radio resource and an uplink radio resource to be used for transmission of a known signal from a communication terminal are associated for null steering to be performed based on the known signal. A correction value calculating unit calculates a first correction value used to correct a downlink quality value obtained by a communication terminal. The correction value calculating unit calculates a second correction value used to correct a downlink quality value obtained by a communication terminal.
