Abstract: There is provided a communication device that transmits a wireless signal using a plurality of bands.
The communication device that transmits data in a plurality of bands includes: a first queue for each band that stores data to be transmitted in each band; a second queue common to at least two bands of the plurality of bands, the second queue storing data to be transmitted with high priority; and a control unit that controls transmission of the data stored in the first queue and the second queue. The communication device transmits information regarding the first queue and the second queue. The second queue stores the retransmission data together with information regarding a band of first transmission.

Abstract: Provided is a communication apparatus and a method that allow for synthesis of information using an original signal and a retransmission signal for retransmitting information of the original signal whose demodulation has failed, in wireless communication with independent physical layer and MAC layer. Information is transmitted regarding a configuration of a retransmission signal for retransmitting information of an original signal whose demodulation has failed to a sender of the retransmission signal, and the retransmission signal transmitted from the sender is received on the basis of the information regarding the configuration of the retransmission signal transmitted.

Abstract: To provide a communication apparatus that realizes data sharing and coordinate transmit of shared data. A communication apparatus that operates as an access point includes: a communicating unit configured to transmit and receive wireless signals; and a control unit configured to control communication operations in the communicating unit, the communication operations including a communication operation for sharing data to be simultaneously transmitted to a single communication terminal between adjacent access points and a communication operation for recognizing that sharing of the data has been completed. The control unit is configured to perform control when transmitting the shared data simultaneously with the adjacent access points so as to multiplex the shared data with a transmission stream addressed to another communication apparatus and transmit the shared data as a multi-user multiplexed stream.
