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 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: 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.

Abstract: In a wireless local area network system including a plurality of types of access points (APs), a first type AP receives a trigger frame from a second type AP, wherein the trigger frame may include first information related to resource allocation for a first block acknowledgment (BA) frame transmitted by a station (STA) to the first type AP. The first type AP may transmit, to the STA, a physical protocol data unit (PPDU) including data for the STA and the first information. The first type AP may receive, from the STA, the first BA frame on the basis of the first information.

Abstract: In a wireless local area network (wireless LAN) system, a transmitting STA can transmit, to a receiving STA, a grouping initiation frame for generating a group that is to perform sensing. The grouping initiation frame can include information related to a session identifier (ID) for a sensing session and to the number of transmission times of a sensing signal performed in the sensing session. The transmitting STA can receive a grouping response frame from the receiving STA. The receiving STA can be included in the group on the basis of the reception of the grouping response frame from the receiving STA within a threshold time preset from the transmission time of the grouping initiation frame. The sensing session can include at least one transmission opportunity (TXOP).

Abstract: The present specification proposes various technical characteristics that may be applied to a Wireless Local Area Network (WLAN) sensing. For example, the present specification proposes a procedure for WLAN sensing using multiple channels or multiple resources. The same or different channels and/or resources may be allocated to at least one wireless device performing the WLAN sensing. The at least one wireless device may perform measurement and signal transmission/reception processes that are included in the WLAN sensing by using the channel(s) and/or resource(s).
