    Abstract: Disclosed are a frame transmission method using a selective beamforming and a communication apparatus to perform the frame transmission method. The communication apparatus may determine a beamforming matrix based on classification information in which a plurality of subcarriers used for communication is classified into a plurality of frequency units, may map a long training field (LTF) sequence to the beamforming matrix, and transmit a beamforming training (BF-T) frame including the mapped LTF sequence to a plurality of stations, may receive, from the plurality of stations having receiving the BF-T frame, feedback information generated based on a reception strength of the BF-T frame, and may allocate frequency units to data frames to be transmitted to the plurality of stations based on the feedback information, and transmit the data frames using the allocated frequency units. The reception strength of the BF-T frame may be determined at each station for each frequency unit.

    Abstract: The present invention relates to a method for efficient transmission of a request frame such as an RTS/CTS frame and a response frame in response to the request frame in a multi-user based wireless communication system. The method of the present invention comprises: a process where wireless terminals transmit a response frame at their own response frame transmission time through a request frame that contains information about a plurality of wireless terminals and information about the response frame transmission time of the respective wireless terminals; a process where the respective wireless terminals transmit a response frame according to a token scheme such that the response frame is transmitted to a final access point; and a process where only a representative wireless terminal selected depending on a given wireless environment receives the response frame.
