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 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: Proposed are a method and device for performing sensing in a wireless LAN system. Specifically, a transmission STA generates a frame. The transmission STA transmits the frame to a reception STA in a 60 GHz band. The frame includes an EDMGHeader-A field. A reserved bit of the EDMG-Header-A field includes a packet classification descriptor. The packet classification descriptor includes information indicating that the frame is a sensing frame used for sensing.

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: 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.
