TRANSMITTER APPARATUS, RECEIVER APPARATUS AND RADIO COMMUNICATION APPARATUS

摘要

A MAC part (10) divides data, which are to be transmitted, into the number of used channels to produce transmitted data. A used-channel notifying part (11) inserts, into an area used only for the transmitted data, channel information used for identifying the used channels. Transmission processing parts (20a-20d) corresponding to the respective used channels produce radio frames from the transmitted data into which the channel information has been inserted, and then transmits the produced radio frames to a radio communication apparatus on the other end.
