摘要： Provided is a radio communication system in which a base station apparatus with a plurality of transmission antennas spatially multiplexes and transmits a transmission signal addressed to a plurality of mobile station apparatuses, and in which the mobile station apparatuses receive the signal transmitted from the base station apparatus. The mobile station apparatuses select a desired precoding vector from predetermined candidates, and give the base station apparatus information identifying the selected precoding vector. The base station apparatus generates a linear filter on the basis of the information from the mobile station apparatuses, grasps multi-user interference that at least one of the mobile station apparatuses is subjected to when the generated linear filter is used, generates a new transmission signal by subtracting the multi-user interference from the transmission signal, and spatially multiplexes the transmission signal addressed to the plurality of mobile station apparatuses by multiplying the new transmission signal by the linear filter. Thus, favorable reception characteristics can be obtained while CSI feedback is performed efficiently.

摘要： A terminal device notifies a base station device about control information associated with a receive quality of the terminal device. The base station device performs data modulation on a plurality of pieces of transmit data for the terminal device, by using a plurality of different data modulation schemes one by one, based on the control information, and spatially multiplexes the plurality of pieces of transmit data after the data modulation over a single wireless resource and transmits a spatially multiplexed signal. The terminal device receives the signal with the plurality of pieces of transmit data spatially multiplexed, and detects desirable transmit data from the receive signal, based on a first channel matrix which represents channel state information between the base station device and the terminal device and a second channel matrix in which the first channel matrix is multiplied by a transform matrix. Accordingly, an adaptive modulation technology is applied even to MIMO spatial multiplexing transmission using a LR technology, and hence a wireless communication system and so forth that can contribute to improvement in frequency utilization efficiency can be provided.

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.
