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: Disclosed are a method and apparatus for an access point (AP) to control channel access of a station in a wireless local area network (WLAN) system. An AP according to one embodiment may determine resource allocation information for protecting a resource for a station not referring to traffic indication map (TIM) information. The determined resource allocation information is transmitted to a station referring to the TIM information, and the station referring to the TIM information does not conduct channel access in a time period specified in the resource allocation information.
