Abstract
A communication apparatus which generates a single physical frame including a plurality of MAC frames, and which transmits the physical frame. The physical frame has variable-length bitmap information which includes bits corresponding to the plurality of MAC frames, respectively, and length information of the bitmap information. The communication apparatus can include a transmission scheme selecting device configured to select a transmission scheme of the physical frame to be transmitted as a response to the polling frame from a plurality of candidates in such a manner as to adapt to a channel estimate result estimated by the channel estimating device. The transmission scheme in this arrangement includes at least one of a modulation scheme and a coding ratio.
