PROBLEM TO BE SOLVED: To enable execution of effective precoding in a MIMO system.SOLUTION: A method includes: selecting a first precoding matrix to be applied to signals transmitted from a first antenna set and a second antenna set included in a communications partner device, and a second precoding matrix to be applied only to signals transmitted form the second antenna set; and informing the communications partner device of control information including precoding matrix information (PMI) indicative of the first precoding matrix and the second precoding matrix. |
