摘要：
The present invention makes it possible to feed back PMIs that are required to generate precoding weights, while securing improvement of throughput performance, in downlink MIMO transmission using a plurality of transmitting antennas. With the present invention, in a mode to include a PTI (Precoder Type Indicator) in a PUCCH and feedback the PTI to a radio base station apparatus for downlink MIMO transmission using a plurality of transmitting antennas, the transmission cycle of feedback information corresponding to report 2 and report 3 when the value of the PTI is 0 are made different from the transmission cycle of feedback information corresponding to report 2 and report 3 when PTI=1 and the former feedback information and the latter feedback information are multiplexed, and the multiplexed signal is transmitted to the radio base station apparatus by the PUCCH.
