Abstract: Proposed are a method and apparatus for performing sensing in a wireless LAN system. In detail, a transmission STA transmits a first trigger frame that requests sensing from a reception STA. The transmission STA receives a response frame to the first trigger frame from the reception STA. The transmission STA transmits a second trigger frame that requests a first sensing frame from the reception STA. The transmission STA receives the first sensing frame from the reception STA. The transmission STA performs channel measurement on the basis of the first sensing frame and obtains sensing information.

Abstract: Proposed are a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives the EHT PPDU from a transmission STA through a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information about a pilot tone. The information about the pilot tone includes allocation information indicating that a first pilot tone for the 320 MHz band is configured by repeating a second pilot tone for an 80 MHz band defined in an 802.11ax wireless LAN system. The first pilot tone is received in a data field on the basis of the allocation information.

Abstract: Proposed are a method and an apparatus for receiving an MAC address of another STA within a reception MLD in a wireless LAN system. Specifically, the reception MLD receives an ML element from a transmission MLD through a first link. The reception MLD decodes the ML element. The ML element includes common information and link information. The link information includes a profile field of the second transmission STA. The profile field of the second transmission STA includes first information relating to whether an MAC address of the second transmission STA exists. If the first information is configured to be 1, the profile field of the second transmission ST A includes the MAC address of the second transmission STA.

Abstract: A method and apparatus for transmitting an EHT PPDU in a wireless LAN system is proposed. Specifically, a transmitting STA generates an EHT PPDU including a STF signal. The transmitting STA transmits the EHT PPDU to a receiving STA. The STF signal is generated on the basis of an EHT STF sequence for a 320 MHz band or a 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a predetermined M sequence is repeated, which is defined as {M 1 M 1 M 1 −M 0 M 1 −M 1 −M 1 M 0 M 1 M 1 M 1 −M 0 −M −1 M −1 M −1 −M}*(1+j)/sqrt(2). The sqrt( ) represents the square root. The predetermined M sequence is defined as M={−1, −1, −1, 1, 1, 1, −1, 1, 1, 1, −1, 1, 1, −1, 1}.

Abstract: Proposed are a method and a device for receiving significant update information regarding a specific AP via a management frame in a WLAN system. Specifically, a reception MLD receives a management frame from a transmission MLD via a first link. The reception MLD decodes the management frame. The management frame includes a notification method mode field. If a significant update on a second transmission STA occurs, a value of the notification method mode field is set to 1, and the management frame includes significant update information of the second transmission STA.

Abstract: In a Wireless Local Area Network system, an STA may receive a trigger frame from an AP. The trigger frame may include a common information field and user information fields. Each of the user information fields may include a first field related to an association identifier (AID) and a second field including information for the STA related to the AID. The second field may include special information for every STA receiving the trigger frame on the basis that the first field has a specific value. The common information field may include a present field related to whether a user information field in which the first field has the specific value is present among the user information fields.
