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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for receiving feedback frame in wireless LAN system","description":"Proposed are a method and device for receiving a feedback frame in a wireless LAN system.
