Abstract: In a wireless local area network (LAN) system, a sharing access point (AP) may transmit a first selection frame to a first shared AP and transmit a second selection frame to a second shared AP on the basis of information relating to channels between a reception station (STA) and the first shared AP and between the reception STA and the second shared AP. The sharing AP may receive a first selection response frame from the first shared AP. The sharing AP may determine to use the first shared AP in multi-AP transmission on the basis of the first selection response frame.

Abstract: Disclosed in the present specification are a method for transmitting and receiving a signal including a physical protocol data unit (PPDU) in a wireless LAN (WLAN) system and an apparatus therefor. Specifically, disclosed in the present specification are a method for transmitting and receiving a signal and an apparatus therefor, which, in a PPDU supported by a specific wireless LAN system, can minimize an overall length error (also known as “spoofing error”) of the PPDU that is assumed to occur between a station capable of decoding all fields in the PPDU and a station capable of decoding only some fields in the PPDU.

Abstract: Proposed are a method and apparatus for transmitting a feedback frame in a wireless local area network (WLAN) system. Specifically, a first STA generates the feedback frame based on multi user (MU)-multi input multi output (MIMO) beamforming. The first STA transmits the feedback frame to a second STA. The feedback frame includes information related to a feedback subcarrier for a predetermined frequency band and a beamforming report field for the MU-MIMO beamforming. The feedback subcarrier includes a first subcarrier transmitted first in the feedback subcarrier and a second subcarrier of which a subcarrier index is determined based on a grouping value related to a subcarrier spacing. The beamforming report field includes a first signal to noise ratio (SNR) for the first subcarrier and a first differential SNR for the second subcarrier. The first differential SNR is an SNR difference between adjacent subcarriers included in the feedback subcarrier.

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: A method of transmitting and receiving a signal, which is transmitted by a station in a wireless communication system, is disclosed in the present specification. The method can include the steps of receiving a PPDU and performing beamforming training based on a TRN field of the received PPDU. In this case, a training length field belonging to an L-header field of the PPDU indicates a length of the TRN field from the timing at which the PPDU ends in reverse order and a length field belonging to the L-header field of the PPDU can indicate a length resulted from subtracting the length of the TRN field indicated by the training length field from a length of the PPDU after the L-header field.
