Abstract: According to one embodiment, a wireless communication device includes: a receiver configured to receive a plurality of first frames each including first information required for uplink multi-user transmission; and a transmitter configured to transmit a second frame generated on the basis of the first information included in the plurality of first frames. The transmitter does not transmit a transmission request for the first information before the first frames are received. The second frame is a frame instructing transmission of a third frame including data after a predetermined time from reception of the second frame.

Abstract: According to one embodiment, a wireless communication device, includes: a receiver configured to receive a first frame a transmitter address of which is an address of a first wireless communication device and a receiver address of which is an address of the wireless communication device; and a transmitter configured to transmit a second frame generated using a first address process in response to receipt of the first frame. The first address process is a process to set a first value in a first region in a receiver address field of the second frame. The first value is a value different from values settable in first regions in addresses of the first wireless communication device and another wireless communication device capable of receiving the second frame.
