Abstract: Provided are a method and apparatus for transmitting a frame in a wireless LAN (WLAN) system. Specifically, a first station (STA) transmits a Link Measurement Request frame requesting Transmit Power Control (TPC) information to a second STA. The first STA receives a Link Measurement Report frame from the second STA. The Link Measurement Report frame being transmitted as a response to the Link Measurement Request frame. The Link Measurement Request frame includes a TPC Configuration field. The TPC Configuration field includes a first sub-field and a second sub-field. The first sub-field includes information on whether or not the Link Measurement Request frame is transmitted through a channel on which channel aggregation is performed. The second sub-field includes information on a number of transmit chains being used for transmitting the Link Measurement Request frame. If the Link Measurement Request frame is transmitted through the channel on which the channel aggregation is performed, the number of transmit chains is equal to an even number.

Abstract: Proposed are a method and apparatus for transmitting a feedback frame in a wireless LAN (WLAN) system. Specifically, a first station (STA) generates a feedback frame based on a multi input multi output (MIMO) beamforming procedure. The first STA transmits the feedback frame to a second STA. The feedback frame is transmitted through an aggregated channel in which a first channel and a second channel are aggregated. The feedback frame includes a first beamforming feedback matrix transmitted on the first channel and a second beamforming feedback matrix transmitted on the second channel. The feedback frame includes a third beamforming feedback matrix when the feedback frame is not transmitted through the aggregated channel. The number of columns of the third beamforming feedback matrix is set to Nc, and the number of rows of the third beamforming feedback matrix is set to Nr. Nc is determined based on the total number of spatial streams supported by the first STA. The number of columns of the first beamforming feedback matrix is set to Nc/2, and the number of rows of the first beamforming feedback matrix is set to Nr/2. The number of columns of the second beamforming feedback matrix is set to Nc/2, and the number of rows of the second beamforming feedback matrix is set to Nr/2.
