The directivity of an antenna is efficiently trained between a transmitter and a receiver, and the training results are efficiently fed back from the receiver to the transmitter. In the case where the order of transmit beam patterns corresponding to individual time slots in a beam training signal, and the names representing the respective transmit beam patterns have already been shared through pre-setting or pre-negotiation between the transmission and reception, the receiving end can estimate received power for each time slot on the basis of transition of the received power of the beam training signal, and writes the transmit beam pattern name or time slot number corresponding to the time slot that realizes the maximum received power, in a notification signal for feedback.
