In user terminal 20, communication section 202 receives a data signal to which precoding based on first channel information indicating a channel between radio base station 10 and user terminal 20 estimated in first channel estimation and beamforming are applied. The first channel information is an equivalent channel matrix including a beamforming weight. Stage-2 channel estimation section 205 performs second channel estimation for estimating second channel information indicating a channel between radio base station 10 and user terminal 20. The second channel information is an equivalent channel matrix including the beamforming weight and a precoding matrix. Postcoding section 207 performs postcoding on the data signal based on the second channel information.
