Abstract: According to one embodiment, a wireless communication device includes a receiver and controlling circuitry. The receiver receives a first frame transmitted by a first wireless communication device in a predetermined frequency band. The controlling circuitry performs channel estimation based on the first frame to acquire channel information between the first wireless communication device and the wireless communication device. The receiver receives a second frame transmitted by a second wireless communication device. The controlling circuitry calculates, using the channel information, weight coefficients for a plurality of antennas to suppress reception of a signal from the first wireless communication device. The receiver receives, using the weight coefficients, a third frame transmitted in the predetermined frequency band from the second wireless communication device after a predetermined time from transmission of the second

The transmitter transmits a first frame containing notification information to specify first and second wireless terminals and a second frame for channel estimation. The receiver receives a third frame transmitter from the first wireless terminal and a fourth frame transmitted from the second wireless terminal. The third frame and the fourth frame are transmitted in a multiplexing scheme by the first and the second wireless terminals. The third frame contains first channel information estimated based on the second frame. The fourth frame contains second channel information estimated based on the second frame.
