摘要： A wireless communication system includes a base station apparatus having a plurality of antennas and a plurality of mobile station apparatuses each having, at least, one antenna. The base station apparatus acquires channel state information of the plurality of mobile station apparatuses, based on any one of a plurality of different channel state information formats, and, separately precodes data signals addressed to the plurality of mobile station apparatuses based on the channel state information, and spatially multiplexes and transmits the precoded signals. The mobile station apparatus receives the precoded signals and detects a desired data signal from the multiplexed signals addressed to mobile station apparatuses, based on the channel state information. With this scheme, it is possible to realize a new spatial multiplexing technology that enables a plurality of mobile station apparatuses using different CSI feedback schemes to be spatially multiplexed on the same wireless resource in the downlink MU-MIMO transmission.
