1. A wireless communication device communicating with a second wireless communication device, comprising:
a receiver configured to
receive a terminal identifier of a first terminal being a target for downlink frequency multiplexing transmission from the second wireless communication device, the first terminal existing at a neighbor area of being judged by the second wireless communication device that interference from the wireless communication device is small and the terminal identifier of the first terminal being allocated by the second wireless communication device, and
receive information identifying, among a plurality of frequency components, a first frequency component allocated to the first terminal;
a controller configured to
select, among a plurality of second terminals belonging to the wireless communication device, a second terminal existing at a neighbor area of being judged by the wireless communication device that interference from the second wireless communication device is small, a terminal identifier of the second terminal being allocated by the wireless communication device and being same as the terminal identifier of the first terminal, and
allocate the first frequency component to the selected second terminal; and
a transmitter configured to transmit a first physical packet in a period at least partially overlapping with a period in which a second physical packet is transmitted from the second wireless communication device, the first physical packet including
(1) a first header containing a plurality of first fields associated with the plurality of frequency components, the terminal identifier of the selected second terminal being set in a field corresponding to the first frequency component among the plurality of first fields, and
(2) a first frame addressed to the second terminal,
wherein the first header is transmitted at a frequency band including the plurality of frequency components and the first frame is transmitted via the first frequency component, the transmitter being configured to transmit the terminal identifier of the second terminal and the information identifying the first frequency component to the second wireless communication device,
wherein the second physical packet including
(1) a second header containing a plurality of second fields associated with the plurality of frequency components, the terminal identifier of the first terminal being set in a field corresponding to the first frequency component among the plurality of second fields, and
(2) a second frame addressed to the first terminal, the second header being transmitted at the frequency band including the plurality of frequency components and the second frame is transmitted via the first frequency component, and
a format of the first header being the same as a format of the second header.
