Abstract: A plurality of pieces of data is properly transmitted with use of a plurality of beams. Data generated in an application is divided into a plurality of pieces of data, different priories are assigned to the plurality of pieces of data, and the plurality of pieces of data is transmitted with a plurality of beams. A beam quality acquiring section acquires quality of each of the plurality of beams. A beam evaluating section performs evaluation of the plurality of beams on the basis of quality of each of the beams. A beam assigning section determines a correspondence between the plurality of beams and the plurality of pieces of data on the basis of evaluation of the beams and the priorities of data. A controller controls a transmitter to transmit the plurality of pieces of data through the corresponding plurality of beams.

Abstract: A communication device that performs processing for estimating out-of-band leakage power is provided. The communication device includes a communication unit that transmits and receives wireless signals in a first frequency band and a second frequency band, and a control unit that controls a communication operation in the communication unit, transmits a reference signal in the first frequency band and the second frequency band, and receives a communication result from a transmission destination of the reference signal. The control unit determines the transmission destination of the reference signal on the basis of results of exchange of capability information with the first terminal and the second terminal, and performs control such that a notification signal for notifying of transmission of the reference signal in advance is transmitted in the first frequency band and the second frequency band.
