According to one embodiment, a wireless communication device includes a reception circuit receiving a frame including first and second data units, the first and second data units each including first and second data areas, the first data area including channel bandwidth information; and a control circuit controlling the reception circuit. The reception circuit receives the first data area with a first frequency bandwidth corresponding to a first channel bandwidth for the first data unit. When the channel bandwidth information indicates a second channel bandwidth, the control circuit switches, before reception of the second data, a frequency bandwidth of the reception circuit to a second frequency bandwidth corresponding to the second channel bandwidth. |
