    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.

    摘要： The present invention is designed to reduce the space to install antennas and still increase the system capacity despite the state of the distribution of user terminals in cells. According to the radio communication method of the present invention, a radio base station apparatus selects precoding vectors from a codebook that is set in advance to be uneven with respect to the direction of the arrangement of antenna elements, based on communication quality information of the user terminals in the cell, multiplies signals to supply to each antenna element by the selected precoding vectors, and transmits the signals multiplied by the precoding vectors to the user terminals, and the user terminal receives a signal from the radio base station apparatus, extracts a reference signal from the received signal and measures channel quality; and feeds back a communication quality feedback signal, including the measured channel quality, to the radio base station apparatus, via the uplink.
