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.

Abstract: In a wireless local area network (LAN) system, a transmission STA may generate capability information related to WLAN sensing. 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: Proposed are a method and apparatus for performing sensing in a wireless LAN system. In detail, a transmission STA transmits a first trigger frame that requests sensing from a reception STA. The transmission STA receives a response frame to the first trigger frame from the reception STA. The transmission STA transmits a second trigger frame that requests a first sensing frame from the reception STA. The transmission STA receives the first sensing frame from the reception STA. The transmission STA performs channel measurement on the basis of the first sensing frame and obtains sensing information.

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.

Abstract: According to various embodiments, a multi-link device including a first STA and a second STA may receive a first PPDU by means of the first STA. The PPDU may include information about traffic buffered in the second STA operating in a second link. In response to the first PPDU, the multi-link device may change the second STA from a doze state to an awake state, and transmit information about the state of the second STA by means of the second STA.

Abstract: According to various embodiments, a multi-link device operating in a plurality of links can transmit, via a first link, a request frame for changing the first link from among the plurality of links to a second link not included in the plurality of links. The multi-link device can receive a response frame via the first link on the basis of the request frame. The multi-link device can change the first link to the second link on the basis of the response frame.

Abstract: According to various embodiments, a multi-link device including a first STA and a second STA may receive, via the first STA, at least one PPDU within a transmission opportunity (TXOP) configured in a first link. While the at least one PPDU is received, the state of the second STA may be set to a doze state. The multi-link device may receive, via the first STA, a first control frame for the truncation of the TXOP. The multi-link device may change the state of the second STA from the doze state to an awake state on the basis of the first control frame.

Abstract: One embodiment according to the present specification relates to a technique for transmitting a long training field (LTF) signal in a wireless LAN (WLAN) system. The LTF signal may comprise an LTF sequence transmitted on the basis of a plurality of subcarriers. For example, a minimum subcarrier index of a plurality of subcarriers may be set to −28, and a maximum subcarrier index of the plurality of subcarriers may be set to 28. A pilot tone may be inserted/allocated to four subcarriers from among a plurality of subcarriers.
