PROBLEM TO BE SOLVED: To achieve precise estimation of interference from a cooperative cell; to complete accurate update of channel quality indication (CQI); to avoid the occurrence of a case when the CQI of UE is estimated high or low; to achieve precise user scheduling; and to improve system performance.SOLUTION: A base station determines the degree of matching between the receiver of UE (user equipment), which is a service target of the self-station, and a cooperative cell channel (101); and determines interference power received in the UE from the cooperative cell, on the basis of the degree of matching between the UE receiver and the cooperative cell channel (102); and determines signal power received in the UE on the basis of the CSI which is fed back from the UE (103); and then updates the CQI on the basis of the interference power and signal power received in the UE from the cooperative cell, to select a modulation coding system and perform user scheduling for the UE, on the basis of the updated CQI (104). |
