Abstract: Provided are a method and apparatus for requesting complete information or partial information on access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD includes a first transmitting station (STA) operating in the first link and a second transmitting STA operating in a second link. The receiving MLD includes a first receiving STA operating in the first link and a second receiving STA operating in the second link. The probe request frame includes a profile field of the second receiving STA.

Abstract: Provided are a method and apparatus for receiving only complete information on other access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The probe request frame includes a frame body and a profile field of a second receiving station (STA). When a first receiving STA does not request complete information on the first link and requests complete information on the second link, the complete information on the second link is requested based on the profile field of the second receiving STA. The probe response frame does not include the complete information on the first link, and includes only the complete information on the second link.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links can receive a PPDU through a first link from among the plurality of links. The PPU can include a first information field related to a second link that is differentiated from the first link. The first information field related to a second link can include a second information field related to a link identifier of a second link and a third information field related to whether all pieces of element information related to a second link is included in the PPDU.

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 STA includes 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 (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.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links may transmit a first request frame for requesting information on the plurality of links. The multi-link device may receive a first response frame on the basis of the first request frame. The first response frame may include information on a ratio of stations (STAs) using a first link as an anchor link, and information on a ratio of STAs using a second link as an anchor link.

Abstract: A transmitting multi-link device (MLD) in a wireless local area network system enables a first station (STA) to perform a back-off operation again without transmitting PPDU, if a second STA is in the middle of receiving even when a back-off counter (BC) of the first STA becomes 0. The first STA and the second STA are included in the same transmitting MLD. The first STA operates on a first link and the second STA operates on a second link. The first and second links are included in a non-simultaneous transmit and receive (NSTR) link pair.
