    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: The present disclosure provides communication apparatus and communication method for channel estimation. The communication apparatus comprises circuitry, which, in operation, generates a signal comprising one or more non-legacy long training field (LTF) symbols, each of the one or more non-legacy LTF symbols comprising a plurality of data tones and a plurality of pilot tones, maps a non-legacy LTF sequence to the plurality of data tones and the plurality of pilot tones, and groups the plurality of data tones with nonzero non-legacy LTF sequence values into a first tone group and a second tone group; and a transmitter which, in operation, transmits the generated signal.
