Abstract
A channel estimation unit estimates channel state information to or from a base station device. A feedback information generation unit performs a decomposition process for the channel state information and thereby acquires first decomposition information that includes plural singular values and second decomposition information that includes plural right singular vectors respectively associated with the plural singular values. The feedback information generation unit mutually replaces portions of the plural singular values, thereby acquires first replacement information, and further acquires second replacement information based on the first replacement information and the plural right singular vectors. The feedback information generation unit performs a conversion process for the second replacement information and thereby acquires second conversion information. A radio transmission unit notifies the base station device of the second conversion information.
