Abstract: Proposed are a method and a device for requesting the same partial information for all transmission STAs within a transmission MLD and responding thereto in a wireless LAN system. Specifically, a reception MLD transmits an ML probe request frame through a first link from the transmission MLD. The reception MLD receives an ML probe response frame through the first link from the transmission MLD. The ML probe request frame includes a first frame body and a probe request ML element. When the first reception ST A requests the same partial information for all transmission STAs, the first frame body includes a first request element and the probe request ML element does not include a profile sub-element of the second transmission STA.

Abstract: The present specification (disclosure) proposes a method and device for applying a sequence and preamble puncturing to an A-PPDU in a wireless LAN system. Specifically, a reception STA receives an A-PPDU from a transmission STA. The reception STA decodes the A-PPDU. The A-PPDU includes a first PPDU for a primary 160 MHz channel and a second PPDU for a secondary 160 MHz channel. The reception STA is allocated to the secondary 160 MHz channel by SST. The first PPDU is transmitted on the basis of a first sequence for 160 MHz and a first preamble puncturing pattern for 160 MHz. The second PPDU is transmitted on the basis of a second sequence for 160 MHz and a second preamble puncturing pattern for 160 MHz.

Abstract: A method and a device for transmitting a feedback frame in a wireless LAN system are proposed. Specifically, a reception STA receives an NDPA frame from a transmission STA through a 320 MHz band. The reception STA receives an NDP frame from the transmission STA. The reception STA transmits a feedback frame to the transmission STA on the basis of the NDPA frame and the NDP frame. The NDPA frame comprises first and second STA information fields. The first STA information field comprises a first AID subfield and information relating to a first partial band. The second STA information field comprises a second AID subfield and information relating to a second partial band. The first and second AID subfields are configured identically as the AID value of the reception STA.
