Abstract: Presented are a method and a device for requesting and receiving information about other AP corresponding to a nontransmitted BSSID set in a wireless LAN system. Particularly, a reception MLD transmits a multi-link (ML) probe request frame from a transmission MLD through a first link. The reception MLD receives an ML probe response frame from the transmission MLD through the first link. The transmission MLD includes first and second transmission MLDs. The first transmission MLD includes a first transmission STA operating in the first link. The second transmission MLD includes a second transmission STA operating in the first link, and a third transmission STA operating in a second link. The second transmission STA is a transmission STA corresponding to a first nontransmitted BSSID of a set of multiple BSSIDs on the basis of the first transmission STA.

Abstract: Proposed are a method and a device for requesting the same partial information for all transmission STAs within a transmission MLD and responding thereto in a wireless LAN system. Specifically, a reception MLD transmits an ML probe request frame through a first link from the transmission MLD. The reception MLD receives an ML probe response frame through the first link from the transmission MLD. The ML probe request frame includes a first frame body and a probe request ML element. When the first reception ST A requests the same partial information for all transmission STAs, the first frame body includes a first request element and the probe request ML element does not include a profile sub-element of the second transmission STA.

Abstract: Suggested are a method and an apparatus for signaling RSP on the basis of a TWT information frame in a wireless LAN system. Specifically, a first receiving STA receives a beacon frame from a transmitting STA. The first receiving STA transmits a first TWT information frame to the transmitting STA. The beacon frame includes allocation information for the RSP. The first TWT information frame includes a first All TWT field, a first TWT Flow identifier field, and a first Next TWT field. When the first All TWT field is set to 1, the first TWT Flow identifier field is set to 2, and the first Next TWT field is set to 0, the RSP is stopped.

Abstract: The present specification proposes various methods for transmitting restricted TWT scheduling information. According to an embodiment of the present invention, the restricted TWT scheduling information can be transmitted through a beacon frame and another beacon frame other than the beacon frame. According to another embodiment described in the present specification, the restricted TWT scheduling information can be transmitted through a beacon frame and response information to request information transmitted by an STA that has not received the beacon frame.

Abstract: The present specification proposes a restricted TWP operation applicable in an OBSS environment. According to an embodiment described in the present specification, a restricted TWT operation applicable in an OBSS environment can be performed by an STA regardless of the OBSS NAV if a more data field in the final data transmitted before the start of a restricted TWT SP is set to 0.

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.
