摘要： Proposed are a method and device for performing sensing in a wireless LAN system. Specifically, a transmission STA generates a frame. The transmission STA transmits the frame to a reception STA in a 60 GHz band. The frame includes an EDMGHeader-A field. A reserved bit of the EDMG-Header-A field includes a packet classification descriptor. The packet classification descriptor includes information indicating that the frame is a sensing frame used for sensing.

摘要： Disclosed are a method and an apparatus for transmitting and receiving protocol data unit (PDU)-related information in a wireless LAN system. The method by which a first station (STA) transmits an aggregate-medium access control (MAC) protocol data unit (PDU) (A-MPDU) in a wireless LAN system, according to an embodiment of the present disclosure, may comprise the steps of: receiving, from a second STA, one or more of first information, second information, and third information related to the maximum length for the A-MPDU; and transmitting, to the second STA, an A-MPDU having a length less than or equal to the maximum length for the A-MPDU, which is derived from a first type physical layer PDU (PPDU) on the basis of the first information, the second information, and the third information.

摘要： Provided are a method and apparatus for receiving only complete information on other access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The probe request frame includes a frame body and a profile field of a second receiving station (STA). When a first receiving STA does not request complete information on the first link and requests complete information on the second link, the complete information on the second link is requested based on the profile field of the second receiving STA. The probe response frame does not include the complete information on the first link, and includes only the complete information on the second link.

摘要： A method and device for transmitting an NGV frame in a wireless LAN system is proposed. Specifically, a transmission device generates an NGV frame and transmits the NGV frame through a first band. The NGV frame includes an L-STF, an L-LTF, an L-SIG, an NGV-SIG, an NGV-STF, an NGV-LTF, and NGV-Data. The L-STF, the L-LTF, the L-SIG, and the NGV-SIG are duplicated in units of second bands and transmitted through the first band. The NGV-STF, the NGV-LTF, and the NGV-Data are transmitted through a full band of the first band. The first band is a 20 MHz band, and a second band is a 10 MHz band.

摘要： According to various embodiments, a multi-link device (MLD) operating in a plurality of links can receive a PPDU through a first link from among the plurality of links. The PPU can include a first information field related to a second link that is differentiated from the first link. The first information field related to a second link can include a second information field related to a link identifier of a second link and a third information field related to whether all pieces of element information related to a second link is included in the PPDU.

摘要： Proposed are a method and a device for requesting partial information on APs in a transmission MLD in a WLAN system. Specifically, a receiving MLD transmits a probe request frame to a transmission MLD through a first link. The receiving MLD receives a probe response frame from the transmission MLD through the first link. The probe request frame includes a profile field of the second receiving STA. The profile field of the second receiving STA includes a first full information profile subfield. When the first receiving STA requests partial information on the second link, the value of the first full information profile subfield is set to 0, and the profile field of the second receiving STA further includes a first request element. The partial information on the second link is requested on the basis of the first request element.

摘要： Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

摘要： One example according to the present specification relates to a method for identifying the format of a PPDU in a wireless LAN (WLAN) system. A receiving STA may receive a first PPDU. The receiving STA may check at least one extra tone of at least one symbol of the first PPDU. The receiving STA may determine, on the basis of the at least one extra tone, the format of the first PPDU as a repeated PPDU format. Thereafter, the receiving STA may receive a second PPDU including the same data as the first PPDU.
