Abstract: Proposed are a method and device for receiving a feedback frame in a wireless LAN system. Specifically, a first STA transmits an NDPA frame to a second STA. The first STA transmits an NDP frame to the second STA. The first STA receives, from the second STA, a feedback frame transmitted on the basis of the NDP frame. The feedback frame includes information about a beamforming feedback matrix. The information about the beamforming feedback matrix includes a first bit for the index difference between quantized phi of adjacent subcarriers, and a second bit for the index difference between quantized psi of the adjacent subcarriers. The adjacent subcarriers are two adjacent subcarriers starting with the first subcarrier among all of the subcarriers. The first subcarrier is either the left edge subcarrier or the right edge subcarrier. The quantized phi and psi are information about beamforming angles.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. Specifically, a transmitter generates a PPDU and transmits the PPDU to a receiver. The PPDU includes a legacy field and an EHT field. The legacy field includes an L-STF. The EHT field includes a data field. The legacy field is configured on the basis of a CSD value per a transmission chain. The CSD value is determined by a candidate CSD value that is the minimum of the sums of a first absolute value and a second absolute value on the basis of a power ratio. The power ratio is a ratio of received power of the L-STF to received power of the data field. The first absolute value is an absolute value of a value related to 5 percent of a CDF relative to the power ratio. The second absolute value is an absolute value of a value related to 95 percent of the CDF relative to the power ratio.

Abstract: Proposed are a method and device for transmitting EHT PPDU in a wireless LAN system. Particularly, a transmission STA generates first and second LTF symbols. The transmission STA transmits EHT PPDU comprising the first and second LTF symbols to a reception STA. The first and second LTF symbols are generated on the basis of an LTF sequence for first to fourth spatial streams. In the first LTF symbol, the LTF sequence for the first to fourth spatial streams is mapped to tones in four tone units in a frequency domain. In the second LTF symbol, the LTF sequence for the first to fourth spatial streams is mapped to tones in four tone units in a frequency domain. The LTF sequence, for the first to fourth spatial streams, mapped to the frequency domain of the second LTF symbol is mapped to a tone by means of cyclic shifting, by two tones, the LTF sequence, for the first to fourth spatial streams, mapped to the frequency domain of the first LTF symbol.

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: A method for reporting channel information by a station (STA) in a wireless LAN (WLAN) system according to an embodiment of the present invention comprises the steps of: receiving a null data packet announcement (NDP-A) frame from a first access point (AP); when it is determined that the NDP-A frame is for joint transmission of a plurality of APs, measuring a channel for a first AP having transmitted the NDP-A frame and a channel for at least one second AP channel which has not transmitted the NDP-A frame; and transmitting channel information for the plurality of APs, which has been acquired according to a result of the channel measurement, to the first AP, wherein when the NDP-A frame is for the joint transmission, the STA can acquire channel information relating to the plurality of APs through a plurality of NDP frames received from the plurality of APs after receiving the NDP-A frame one time.

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.
