ABSTRACT:
A wireless communication apparatus includes a carrier sense device which determines whether or not the first channel satisfies a specific condition of the determination of an idle state, and an occupation/release control device which performs control to make the first physical layer protocol processing device generate and transmit a first frame which declares that the first channel will be occupied for a first predetermined period by virtual carrier sense, when the specific condition of the determination of the idle state is satisfied, and perform control to make the second physical layer protocol processing device generate and transmit a second frame which declares that the second channel will be occupied for a second predetermined period by virtual carrier sense.
