COMMUNICATION DEVICE AND COMMUNICATION METHOD

Abstract:

A communication device is provided that performs highly reliable data communication using a plurality of channels. The communication device includes: a generation unit that generates a transmission frame including an aggregation frame in which a sequence of subframes is multiplexed in a time axis direction and a frequency channel axis direction; and a transmission unit that wirelessly transmits the transmission frame. The generation unit generates the aggregation frame aggregated to cause each of the subframes included in the sequence to be stored at least once in each of frequency channels, and arranges in the aggregation frame at least one slot for receiving a continuation request signal.
