Abstract: According to one embodiment of the present specification, an STA may be connected to a primary AP and a secondary AP simultaneously. The STA may acquire control information related to whether the secondary AP can acquire a transmission/reception signal of the primary AP. Thereafter, the STA may transmit a UL signal to the primary AP. The STA may transmit, on the basis of whether the secondary AP can acquire the transmission/reception signal of the primary AP, a block acknowledgement request (BAR) signal for a UL signal to the secondary AP.

Abstract: In a wireless local area network (LAN) system, a sharing access point (AP) can determine a Q-matrix related to a first antenna of a first shared AP, a second antenna of the first shared AP, a third antenna of a second shared AP, and a fourth antenna of the second shared AP. The sharing AP can transmit, to the first shared AP, a first value related to the first antenna and a second value related to the second antenna in the Q-matrix. The sharing AP can transmit, to the second shared AP, a third value related to the third antenna and a fourth value related to the fourth antenna in the Q-matrix.

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.
