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 fr ame 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: In a wireless local area network system, a reception MLD may include a plurality of reception stations (STAs). The reception MLD may receive, from a transmission MLD, a first physical protocol data unit (PPDU) including data. The reception MLD may transmit, to the transmission MLD, a block acknowledgement (ACK) (BA) frame regarding the first PPDU. The BA frame may include a first association identifier (AID) information field and a second AID information field. The first AID information field may include a first AID field related to an AID of the transmission MLD and an ACK information field regarding the data. The second AID information field may include a second AID field and a power state information field related to whether the plurality of reception STAs are in an awake state or in a doze state, on the basis of the second AID field having a first value.

Abstract: In a wireless local area network (LAN) system, a sensing session comprises a first burst and a second burst, wherein, in the first burst, a transmitting STA may transmit a first sounding signal to a first receiving STA and a second receiving STA. In the first burst, the transmitting STA may receive, from the first receiving STA, a first feedback frame comprising first channel information between the transmitting STA and the first receiving STA, and, from the second receiving STA, a second feedback frame comprising channel information between the transmitting STA and the second receiving STA. In the second burst, the transmitting STA may receive a second sounding signal from the first receiving STA. In the second burst, the transmitting STA may receive, from the second receiving STA, a third feedback frame comprising channel information between the first receiving STA and the second receiving STA.

Abstract: Proposed are a method and apparatus for receiving important update information via a multi-link element in a wireless LAN system. In detail, a reception MLD receives a multi-link element from a transmission MLD via a first link. The reception MLD decodes the multi-link element. The transmission MLD includes a first transmission STA operating in the first link and a second transmission STA operating in a second link. The multi-link element includes common information and link-specific information. The common information is changed when an important update occurs for the second transmission STA.

Abstract: In a wireless local area network system, an RTS frame may include information associated with the length of the RTS frame. The type of information included in the RTS frame may vary according to the length of the RTS frame. In other words, the RTS frame may include information indicating the type of information included in the RTS frame. The information associated with the length of the RTS frame may further include information associated with the wireless LAN system supported by a reception STA that transmits the RTS frame.

Abstract: A transmitting STA can directly communicate with a receiving STA in a wireless local area network (wireless LAN) system. The transmitting STA can transmit, to an AP, a request signal for a P2P transmission at a determined time or a random time and, when a trigger frame is received from the AP, the transmitting STA can perform P2P communication with a receiving STA on the basis of the trigger frame.
