There is disclosed a wireless communication apparatus in which a first wireless communication using one first channel of two first channels each having a first bandwidth, and a second wireless communication using a second channel having a second bandwidth wider than the first bandwidth and having a band overlapping those of the two first channels are performed. A selection unit selects a Basic Service Set (BSS) operational mode on the basis of a load amount of the other first channel of the two first channels. A generation unit generates a management frame indicating the BSS operational mode selected by the BSS mode selection unit. A transmission unit transmits the management frame.
