Abstract:
1. 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, comprising: a selection unit configured to select a Basic Service Set (BSS) operational mode for a BSS on the basis of a load amount of the other first channel of the two first channels; a generation unit configured to generate a management frame indicating the BSS operational mode selected by the BSS mode selection unit; a transmission unit configured to transmit the management frame; a carrier sense unit configured to determine idle/busy information of the other first channel or the second channel; and a load amount measurement unit configured to measure a load amount of the other first channel or the second channel on the basis of the idle/busy information, wherein the selection unit selects, as the BSS operational mode, one of the BSS modes that is a first BSS mode in which a frame is transmitted by the first wireless communication, a second BSS mode in which a centralized control station alternately switches between a first communication period for performing the first wireless communication and a second communication period for performing the second wireless communication, or a third BSS mode in which a frame is transmitted by either the first wireless communication or the second wireless communication.
