Abstract: A transmission STA in a wireless local area network system can transmit a sensing start frame. The sensing start frame can comprise information relating to a feedback method and feedback frequency. The feedback method can comprise information relating to at least one of an explicit feedback, implicit feedback and hybrid feedback. The transmission STA can transmit a sensing frame to a reception STA. The transmission STA can receive from the reception STA a feedback frame comprising channel state information obtained on the basis of the sensing frame. The sensing start frame can further comprise information relating to the number of sensing frame transmissions. The information relating to feedback frequency can comprise information relating to the number of received sensing frames prior to the transmission of the feedback frame by the reception STA.

Abstract: Proposed are a method and a device for requesting partial information from APs within a transmission MLD in a WLAN system. Particularly, a reception MLD transmits a probe request frame to a transmission MLD via a first link. The reception MLD receives a probe response frame from the transmission MLD via the first link. When the partial information regarding the first link and the partial information regarding the second link are the same, the partial information regarding the second link is requested on the basis of the first request element, and a value of a first full information profile sub-field is set to 0.

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 (LAN) system, a transmission MLD may comprise a first station (STA) and a second station (STA), wherein the first STA operates in a first link, and the second STA operates in a second link. The transmission MLD may transmit a connection request frame to a reception MLD. The connection request frame may comprise capability information related to whether a restricted basic service set (BSS) mode is supported and information related to use of the restricted BSS mode. The information related to the use of the restricted BSS mode may comprise first information related to an STA which operates in the restricted BSS mode, among STAs included in the transmission MLD. The restricted BSS mode may mean a mode in which monitoring for signal reception is performed on the basis of acquisition of information, from an STA not operating in the restricted BSS mode, by the STA operating in the restricted BSS, the information indicating reception of a signal. The transmission MLD may receive a connection response frame from the reception MLD.

Abstract: In a wireless local area network (WLAN) system, an access point (AP) multi-link device (MLD) may include a first AP and a second AP, the first AP may operate in a first link, and the second AP may operate in a second link. A station (STA) MLD may receive BSS information related to the first and second links, in which the AP MLD operates, from the AP MLD through the first link. The BSS information may include information related to the number of single radio STAs operating in the first link and the number of single radio STAs operating in the second link. The STA MLD may determine a link, in which the STA MLD is to operate, on the basis of the BSS information.

The TIM information can include a TIM bitmap and a link bitmap. The TIM bitmap includes a bitmap related to whether data to be transmitted by the AP MLD to each receiving MLD is present, and the receiving MLD can include the STA MLD. The link bitmap can include information related to a link of the receiving MLD, in which the data to be transmitted by the AP MLD is present, from among the receiving MLDs. The STA MLD can receive wake-up link information from the AP MLD. The wake-up link information can include information related to a link to be woken up from among links of the STA MLD.
