Abstract
In user terminal, communication sectionreceives a data signal to which precoding based on first channel information indicating a channel between radio base stationand user terminalestimated 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 sectionperforms second channel estimation for estimating second channel information indicating a channel between radio base stationand user terminal. The second channel information is an equivalent channel matrix including the beamforming weight and a precoding matrix. Postcoding sectionperforms postcoding on the data signal based on the second channel information.
