摘要

A decrease in a transmission capacity is suppressed even when CSI is not fed back from a mobile station apparatus to all cooperating base station apparatuses. A base station apparatus (BS2) decides, according to the presence/absence of CSI fed back from a plurality of mobile station apparatuses (MS (MS1, MS2)), a cooperation target mobile station apparatus (MS2) to which the base station apparatus transmits a signal in cooperation with another base station apparatus (BS1) and a non-cooperation target mobile station apparatus (MS1) to which a specific base station apparatus (BS1) transmits a signal, and generates a precoding weight for the signal transmitted to the cooperation target and non-cooperation target mobile station apparatuses (MSs) based on the channel state information.
