Abstract: Communication devices and methods for multi-band traffic streams are provided. One exemplary embodiment provides a multi-band communication device which includes at least a plurality of transceivers and Media Access Control (MAC) circuitry. In operation, the transceivers each transmit signal frames on different ones of a plurality of frequency bands. The MAC circuitry is coupled to the transceivers and, in operation, receives a multi-band block acknowledgement frame on one of the plurality of frequency bands acknowledging the signal frames transmitted on the plurality of frequency bands. Another exemplary embodiment provides MAC circuitry which in operation generates and transmits a multi-band block acknowledgement frame on one of the plurality of frequency bands acknowledging the signal frames received on the plurality of frequency bands.

Abstract: Provided is a multi-band communication apparatus including a transmitter and a receiver. The transmitter transmits, in a wireless network and to multi-band communication devices, frames on a frequency band that include actions related to the frequency band and to at least one other frequency band in which the multi-band communication apparatus transmits. The receiver receives, in the wireless network, from the multi-band communication devices, frames on the frequency band that include actions related to the frequency band and to the at least one other frequency band in which the multi-band communication apparatus receives.

Abstract: A transmitting method includes: configuring a frame using a plurality of orthogonal frequency-division multiplexing (OFDM) symbols, by allocating a plurality of transmission data to a plurality of areas; and transmitting the frame. The plurality of areas are each identified by at least one time resource among resources and at least one frequency resource among frequency resources. The frame includes a first period in which a preamble is transmitted, and a second period in which the plurality of transmission data are transmitted by at least one of time division and frequency division. The second period includes a first area, and the first area includes a data symbol generated from first transmission data, a data symbol generated from second transmission data and subsequent to the data symbol generated from the first transmission data, and a dummy symbol subsequent to the data symbol generated from the second transmission data.
