  • Publication number: 20260322431
    Abstract: A transmission station transmits a radio signal via a plurality of antennas to establish wireless communication by MIMO under a communication standard supporting a dummy frame. A UW unique to an antenna used for transmission of the dummy frame is imparted to the dummy frame. The dummy frame and a normal frame in which data to be transferred is stored are transmitted from any of the plurality of antennas. A reception station receives the dummy frame, extracts the UW, specifies the antenna of the transmission source of the dummy frame based on the UW, estimates a channel state between the transmission station and the reception station based on the reception state of the dummy frame the antenna of the transmission source of which can be specified, and achieves MIMO transmission for the data stored in the normal frame using a channel matrix representing the channel state.
