Abstract: Proposed are a method and device for acquiring information on links between MLDs in a wireless LAN system. Specifically, a receiving MLD transmits a probe request frame to a 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 comprises: a first transmitting STA operating in the first link; a second transmitting STA operating in a second link; and a third transmitting STA operating in a third link. The receiving MLD comprises a first receiving STA operating in the first link. When the first receiving STA requests for information on the second and third links, the probe request frame includes link identifiers for the second and third links. When the first receiving STA requests for information on all the links, the probe request frame does not include link identifiers for all the links.

Abstract: Proposed are a method and an apparatus for receiving an MAC address of another STA within a reception MLD in a wireless LAN system. Specifically, the reception MLD receives an ML element from a transmission MLD through a first link. The reception MLD decodes the ML element. The ML element includes common information and link information. The link information includes a profile field of the second transmission STA. The profile field of the second transmission STA includes first information relating to whether an MAC address of the second transmission STA exists. If the first information is configured to be 1, the profile field of the second transmission ST A includes the MAC address of the second transmission STA.

Abstract: Proposed are a method and a device for receiving significant update information regarding a specific AP via a management frame in a WLAN system. Specifically, a reception MLD receives a management frame from a transmission MLD via a first link. The reception MLD decodes the management frame. The management frame includes a notification method mode field. If a significant update on a second transmission STA occurs, a value of the notification method mode field is set to 1, and the management frame includes significant update information of the second transmission STA.

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: A method and a device for transmitting updated information for an ML reconfiguration in a wireless LAN system are proposed. Specifically, a reception MLD performs an ML reconfiguration with a transmission MLD. The reception MLD transmits MLD capability information for the ML reconfiguration to the transmission MLD. The transmission MLD comprises a first transmission STA operating in a first link and a second transmission STA operating in a second link. The reception MLD comprises a first reception STA operating in the first link and a second reception STA operating in the second link. The MLD capability information includes information on a change in the number of links supported by the transmission and reception MLDs at the same time.

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: 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.
