Abstract
In order to reduce the amount of feedback information for specifying a precoding weight, the mobile station apparatus generates a control signal for specifying the precoding weight using bits representing a rank indicator (RI) and bits representing a precoding matrix indicator (PMI) from a bit space, including a plurality of bits representing the RI and a plurality of bits representing the PMI, in which the same bits representing the RI are allocated to a plurality of ranks equal to or higher than a predetermined rank. The control signal is transmitted in uplink using the antennas.
