Abstract: Proposed are a method and apparatus for transmitting a SU PPDU to a peer STA in a TXOP period allocated by a trigger frame in a wireless LAN system. Specifically, a first STA receives an MU-RTS frame from an AP. The first STA transmits a CTS frame to the AP. The first STA transmits a first SU PPDU to the AP or a second STA. The MU-RTS frame includes information about a TXOP period in which the first SU PPDU may be transmitted. The CTS frame includes type information. The AP is set to a doze state after the CTS frame is received.

Abstract: Proposed are a method and apparatus for requesting significant update information from APs within a transmission MLD in a wireless LAN system. In detail, a reception MLD transmits a probe request frame to the transmission MLD via a first link. The reception MLD receives a probe response frame from the transmission MLD via the first link. The transmission MLD comprises a first transmission STA operating in the first link and a second transmission STA operating in a second link. The reception MLD includes a first reception STA operating in the first link and a second reception STA operating in the second link. The probe request frame includes a profile field of the second reception STA. The profile field of the second reception STA includes a first significant update request field. When the first reception STA requests partial information regarding the second link and the first significant update request field is set to 1, the partial information regarding the second link is set as significant update information regarding the second link.

Abstract: A method and apparatus for identifying change sequence information in a wireless LAN system are proposed. In detail, an STA receives a DTIM beacon frame and a beacon frame from a first AP. The STA decodes the DTIM beacon frame in a first awake state and decodes the beacon frame in a second awake state. Both the DTIM beacon frame and the beacon frame include a CUF and a CSN. When a significant update of a second AP occurs, a value of the CUF is changed from 0 to 1 until transmission of a next DTIM beacon frame, the value of the CUF is changed from 1 to 0 after the transmission of the next DTIM beacon frame, and the CSN includes updated information. The updated information is decoded in the second awake state regardless of the value of the CUF.

Abstract: Proposed are a method and a device for receiving information on a beacon interval of another AP in a transmitting MLD in a WLAN system. Specifically, a receiving MLD receives an ML element from a transmitting MLD through a first link. The receiving MLD decodes the ML element. The transmitting MLD includes a first transmitting STA operating in the first link and a second transmitting STA operating in a second link. The ML element contains common information and link information. The link information includes information about a beacon interval of the second transmitting STA.

Abstract: Proposed are a method and apparatus for performing sensing in a wireless LAN system. In detail, a first STA broadcasts a sensing request frame. The first STA receives a first sensing response frame form a second STA and receives a second sensing response frame from a third STA. The sensing request frame includes STA identifier information and RU allocation information. The STA identifier information includes identifiers of the second and third STAs. The RU allocation information includes information about a first RU allocated to the second STA and information about a second RU allocated to the third STA. The first sensing response frame is received through the first RU. The second sensing response frame is received through the second RU.

Abstract: In a Wireless Local Area Network system, an STA MLD may include a first STA and a second STA, and an access point (AP) MLD may include a first AP and a second AP. The first STA and the first AP operate over a first link, the second STA and the second AP operate over a second link, and the second STA may be in a doze state. The first STA may receive, through the first link, a notice frame including information related to a critical update that has occurred in the second AP. The second STA may acquire, from the first STA, information related to the critical update. The notice frame may include a management frame.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.
