<P>PROBLEM TO BE SOLVED: To reduce information amount of feedback information to specify a precoding weight. <P>SOLUTION: A mobile station device 10 generates a control signal which specifies the precoding weight based on a bit representing RI and a bit representing PMI from a bit space, which is constructed by a plurality of bits representing RI and a plurality of bits representing PMI and to which bits representing the same RI in a plurality of ranks higher than a predetermined rank is allocated, by using a feedback control signal generation unit 108; and transmits the control signal through antennas RX #1-#N in an uplink. <P>COPYRIGHT: (C)2012,JPO&INPIT |
