According to one embodiment, a wireless communication device includes a transmitter configured to transmit a first field containing information to identify a plurality of wireless communication terminals, and configured to multiplex and transmit a plurality of second fields in each of which a first frame containing an address of any of the wireless communication terminals is set; and a controller configured to determine, for the first frames, values pertaining to lengths of durations to suppress access to a wireless medium to the wireless communication terminal having an address different from the address contained in each of the first frames. The transmitter is configured to set the values in the first frames, the second fields, or the first field. The controller is configured to determine the values so that the durations have an end at an identical time.
