BASE STATION AND CORRECTION VALUE CALCULATION METHOD

WIPO Patent Application WO/2013/047635

A1

In a base station according to the present invention, correspondence relationship between downlink wireless resources and uplink wireless resources to be used for transmitting known signals in a communication terminal is determined for null-steering on the basis of the known signals. A correction value calculation unit calculates a first correction value for a downlink quality value obtained by the communication terminal, on the basis of a response signal which indicates whether or not the communication terminal appropriately receives a signal transmitted to the communication terminal from a communication unit using a corresponding downlink wireless resource which has a correspondence relationship with the uplink wireless resource used by the communication terminal to transmit the known signal. The correction value calculation unit calculates a second correction value for the downlink quality value obtained by the communication terminal, on the basis of a response signal which indicates whether or not the communication terminal appropriately receives a signal transmitted to the communication terminal from a communication unit using a non-corresponding downlink wireless resource which does not have a correspondence relationship with the uplink wireless resource used by the communication terminal to transmit the known signal.
