Abstract
A wireless communication device includes a transmitter and a receiver. 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. The first frame contains at least either information to specify a preamble of the third frame and a preamble of the fourth frame or information to specify a subcarrier used for transmission of the third frame and a subcarrier used for transmission of the fourth frame.
