According to one embodiment, a wireless communication apparatus includes a reception unit, a storage unit, a transfer amount decision unit, and a first transfer control unit. The reception unit receives a first frame with a frame length of a first length using a first wireless method. The storage unit stores the first frame. The transfer amount decision unit sets, when a second length decided based on the first wireless method is smaller than the first length, a third length to be the second length, and sets, when the second length is not less than the first length, the third length to be a value not more than the first length. The first transfer control unit transfers transfer information including first information of the third length in the first frame to a first memory, and transfers the first frame by the first length to a second memory.
