Abstract
Provided is a communication device. The communication device communicating with another communication device, includes: a reception unit configured to receive a signal transmitted from the another communication device; a transmission unit configured to transmit a signal to the another communication device; and a control unit configured to determine a weighting vector to be used in the reception unit and a precoding vector to be used in the transmission unit, in which, in a case where a specific reference signal indicating that the weighting vector used for receiving the signal in the another communication device has been changed is received by the reception unit, the control unit determines the precoding vector to be used for signal transmission by performing channel estimation by using the received specific reference signal, and in which the transmission unit transmits data precoded with the precoding vector determined by the control unit.
