Abstract
A radio communication apparatus that performs first radio communication using a first channel among two first channels each having a first channel width, and second radio communication using a second channel having a second channel width that is wider than the first channel width and also having a channel width overlapping with the two first channels. The apparatus includes an interference detection device which detects that interference occurs in the first channel among the two first channels, and a frame generation unit which generates a notification frame that recommends the use of only the first channel width. An instruction unit instructs the frame generation unit to generate the notification frame when the occurrence of interference is detected by the interference detection device. A frame transmission unit transmits the notification frame generated from the frame generation unit in response to the instruction from the instruction unit.
