摘要： To reduce interference among mobile station apparatuses even when the CSI is not transmitted from all mobile station apparatuses as feedback in an environment where Joint Transmission is performed, a channel matrix is generated which is comprised of the CSI from a plurality of mobile station apparatuses (UEs) undergoing spatial multiplexing for each of coordinated cells, and based on the channel matrix, precoding weights are generated successively starting from a cell having the highest number of mobile station apparatuses (UEs) that transmit the CSI as feedback. When data transmission is targeted for a mobile station apparatus (UE#1) that transmits the CSI as feedback as well as a weight generation target cell that is a target for generation of precoding weights, precoding weights are generated so as not to suppress interference on a mobile station apparatus (UE#2) that transmits the CSI as feedback as well as the weight generation target cell, while suppressing interference on mobile station apparatuses (UE#3, UE#4) that do not transmit the CSI as feedback except the weight generation target cell.
