Abstract: In a wireless local area network (WLAN) system, an STA MLD may include a first STA and a second STA, wherein the first STA operates on a first link, and the second STA operates on a second link. The STA MLD may transmit an association request frame to an access point (AP) MLD. The association request frame may include capability information of a requesting STA, which requests to be associated with the AP MLD, among STAs included in the STA MLD and information related to a request link, to with which a request to be associated is transmitted by the requesting STAs. The STA MLD may receive an association response frame from the AP MLD. The association response frame may include capability information of an AP that operates in a link, an association with which is accepted by the AP MLD, among the request links.

Abstract: 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 STAincludes 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.

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: In a wireless local area network (wireless LAN) system, an initiator station (STA) can transmit a sensing initiation frame. The sensing initiation frame can include information related to a first responder STA operating as a sensing responder. The initiator STA can receive a first transmission initiation frame from the first responder STA. The first transmission initiation frame can include strength information about a first sensing signal. The initiator STA can receive the first sensing signal from the first responder STA. The sensing initiation frame can further include information related to a second responder STA operating as a sensing responder. The initiator STA can receive a second transmission initiation frame from the second responder STA. The second transmission initiation frame can include strength information about a second sensing signal. The second sensing signal can be received from the second responder STA.

Abstract: A transmitting STA can transmit a sensing initiation frame to a first receiving STA in a wireless local area network (wireless LAN) system. The sensing initiation frame can include information related to an STA for transmitting a sounding frame and a session identifier (ID) related to an STA group that is to perform sensing. The transmitting STA can transmit the sounding frame to the first receiving STA. The transmitting STA can receive a first feedback frame for the sounding frame from the first receiving STA. The sounding frame can be a frame transmitted to identify a target. The first feedback frame can include information about a channel changed by means of the target. The sounding frame can include a null data packet announcement (NDPA) frame and a null data packet (NDP) frame.

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 (WLAN) system, in a case where data is being transmitted through a link, a transmission multi-link device (MLD) may perform back-off through another link during a time interval in which a PPDU is not transmitted through the link for the data transmission. Further, the transmission MLD may perform back-off again if a TXOP of the link for the data transmission is not over when a BC becomes 0.
