TERMINAL DEVICE, FEEDBACK INFORMATION GENERATION METHOD, AND BASE STATION DEVICE

摘要

A propagation path estimation unit estimates propagation path information between a terminal device and a base station device. A feedback information generation unit acquires first decomposition information including a plurality of singular values, and second decomposition information including a plurality of right singular vectors associated with the plurality of singular values, respectively, by performing decomposition processing on the propagation path information. The feedback information generation unit acquires first interchange information by interchanging some of the plurality of singular values, and acquires second interchange information on the basis of the first interchange information and the plurality of right singular vectors. The feedback information generation unit acquires second conversion information by performing conversion processing on the second interchange information. A radio transmission unit notifies the base station device of the second conversion information.
