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 (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: A method and a device for transmitting updated information for an ML reconfiguration in a wireless LAN system are proposed. Specifically, a reception MLD performs an ML reconfiguration with a transmission MLD. The reception MLD transmits MLD capability information for the ML reconfiguration to the transmission MLD. The transmission MLD comprises a first transmission STA operating in a first link and a second transmission STA operating in a second link. The reception MLD comprises a first reception STA operating in the first link and a second reception STA operating in the second link. The MLD capability information includes information on a change in the number of links supported by the transmission and reception MLDs at the same time.

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).

Abstract: Proposed are a method and a device for transmitting and receiving important update information of another AP through an ML element in a WLAN system. Specifically, a receiving MLD receives a basic ML element from a transmitting MLD over a first link. The receiving MLD decodes the basic ML element. The basic ML element includes a profile field of the second transmitting STA. The profile field of the second transmitting STA includes a first CSF presence field. When the value of the first CSF presence field is set to 0, the profile field of the second transmitting STA includes a first CSF field. The first CSF field includes information about the current change sequence number of the second transmitting STA.

Abstract: According to various embodiments, a multi-link device (MLD) operating in multiple links including a first link may transmit, through a first station (STA) and to a first AP of an AP multi-link device, a request frame including an information field for requesting at least one element related to a second link. The multi-link device may receive at least one element related to the second link on the basis of the request frame.

Abstract: A method and an apparatus for transmitting a PPDU on the basis of an S-TDMA in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP receives, on the basis of the trigger frame, a first trigger-based frame from the first STA and a second trigger-based frame from the second STA. The trigger frame includes a common information field and a user information field. The common information field includes S-TDMA indication information enabling the S-TDMA to be performed. The user information field includes: allocation information on a first RU to which the first trigger-based frame and the second trigger-based frame are transmitted; first symbol offset information on the first trigger-based frame; and second symbol offset information on the second trigger-based frame.

Abstract: According to various embodiments, a multi-link device including a first STA and a second STA may receive, via the first STA, at least one PPDU within a transmission opportunity (TXOP) configured in a first link. While the at least one PPDU is received, the state of the second STA may be set to a doze state. The multi-link device may receive, via the first STA, a first control frame for the truncation of the TXOP. The multi-link device may change the state of the second STA from the doze state to an awake state on the basis of the first control frame.
