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.

Abstract: A method for a non-simultaneous transmit and receive (non-STR) device in a wireless local area network (LAN) is provided. The non-STR device may support a multi-link communication related to a first link and a second link. The non-STR device may determine whether to transmit a first physical protocol data unit (PPDU), PPDU, based on a channel access result on the first link and a channel access result on the second link. The non-STR device determines not to transmit the first PPDU through the first link and keeps the back-off counter of the first link at zero (0) when a back-off counter of the first link reaches zero (0) and a back-off counter of the second link does not reach zero (0).

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 (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.

Abstract: Proposed are a method and apparatus for performing, by reception MLD, link reconfiguration with transmission MLD, in a wireless LAN system. In detail, the reception MLD transmits a link change request frame to the transmission MLD via a first link. The reception MLD receives a link change response frame from the transmission MLD via the first link. The reception MLD configures a second link with the transmission MLD, on the basis of the link change response frame. The transmission MLD comprises a first transmission STA operating in the first link and a second transmission STA operating in the second link. The reception MLD comprises a first reception STA having a link changed from the first link to the second link. The link change response frame comprises information about the first and second links. The information about the second link is updated. The information about the first link is maintained without being reset or deleted.

Abstract: In a wireless local area network system, a transmission MLD may comprise a first station (STA) and a second STA, wherein the first STA operates on a first link and the second STA operates on a second link. The transmission MLD may transmit, to a reception MLD, capability information regarding whether power saving is supported. The power saving may be performed by one method among first to third power saving methods. The transmission MLD may transmit, to the reception MLD, a control frame comprising method information regarding which method among the first to third power saving methods is to be used.

The capability information may comprise a common part and an individual part. The common part may comprise sensing support band information including information related to whether WLAN sensing performed in a sub 7 GHz band is supported, and information related to whether WLAN sensing performed in a 60 GHz band is supported. The individual part may comprise, on the basis of the sensing support band information, at least one of capability information for WLAN sensing performed in the sub 7 GHz band, and capability information for WLAN sensing performed in the 60 GHz band. The transmission STA may transmit the capability information to a reception STA.

Abstract: The present disclosure proposes a transmitting multi-link device (MLD) including a first station (STA) operating on a first link and a second STA operating on a second link. The transmitting MLD acquires a first transmission opportunity (TXOP) in the first link and transmits a first physical protocol data unit (PPDU) in the first link. The transmitting MLD receives a block acknowledgment (BA) frame for the first PPDU in the first link and transmits a second PPDU in the first link. The transmitting MLD changes a responder of the first TXOP based on not receiving, from the receiving MLD, a BA frame for the second PPDU within a preconfigured time interval in the first link.
