ABSTRACT:
According to one embodiment, a radio communication apparatus includes a first reservation slot securing unit, a second reservation slot securing unit and a radio communication unit. The first reservation slot securing unit secures a first reservation slot for performing radio communication through a first transmission output in a radio communicable slot to be shared in time division in a group by adjustment in periodically formed beacon slots. The second reservation slot securing unit secures a second reservation slot for performing radio communication through a second transmission output smaller than the first transmission output in the radio-communicable period, when the first reservation slot securing unit fails in securing the first reservation slot. And the radio communication unit performs radio communication through the first transmission output or the second transmission output by using at least either the first reservation slot or the second reservation slot.
