Abstract:
1. A wireless communication apparatus, comprising: a first physical layer protocol processing device configured to perform physical layer protocol processing for wireless communication using one first-channel of two first-channels, or other first-channel of the two first-channels, the first-channels each having a first bandwidth; a second physical layer protocol processing device configured to perform physical layer protocol processing for wireless communication using a second-channel having a second bandwidth which is wider than the first bandwidth, and overlapping the two first-channels; a state management device configured to determine whether or not the one first-channel satisfies a specific condition of determination of an idle state; and a control device configured to perform control to, upon receiving a determination result which indicates that the one first-channel satisfies the specific condition of determination of the idle state, make the first physical layer protocol processing device transmit a first frame for occupation of the one first-channel for a first period, the control device further configured to make the first physical layer protocol processing device or the second physical layer protocol processing device transmit a second frame for occupation of the other first-channel for a second period, after transmission of the first frame, the control device still further configured to transmit a third frame for termination of occupation of the second-channel, after transmission of the second frame.
