Abstract
A terminal device is provided for solving the problem of large overhead expended in the PMI calculation process. A reception quality measurement unit () measures, for each block frequency band, the reception quality of a signal received by a communication processing unit (). A reception quality judgment unit () determines for each block frequency band whether the reception quality is greater than a first threshold value. A calculation unit () individually computes the individual PMI for each frequency band for which the reception quality is equal to or less than the first threshold value, and further, computes for each frequency band for which the reception quality is greater than the first threshold value a common PMI that is common to these frequency bands. A report unit () reports to the wireless base station the correspondence between the frequency bands and the individual PMI and common PMI that were computed.
