Abstract: In a Wireless Local Area Network system, a reception device can receive information about link deactivation, and deactivate a link. The proposed method includes receiving a physical protocol data unit (PPDU) including a first control field in a first link. In the method, the first control field may include information related to disablement of the first link and information on a time point at which the first link is disabled. The proposed method further includes disabling the first link based on the first control field.

Abstract: In a wireless local area network system, a station (STA) generates a physical (PHY) protocol data unit (PPDU) including at least one subframe and information related to a subframe length, wherein the subframe may include a medium access control (MAC) protocol data unit (MPDU) and a padding bit. The length of the padding bit may be determined such that the length of the subframes is an integer multiple of a codeword length. The information related to the subframe length may be information on the number of codewords related to the subframe length. A step in which the STA transmits the PPDU may be comprised.

Abstract: Provided are a method and apparatus for requesting complete information or partial information on access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the 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 includes a first transmitting station (STA) operating in the first link and a second transmitting STA operating in a second link. The receiving MLD includes a first receiving STA operating in the first link and a second receiving STA operating in the second link. The probe request frame includes a profile field of the second receiving STA.

Abstract: In a wireless local area network system including a plurality of types of access points (APs), a first type AP receives a trigger frame from a second type AP, wherein the trigger frame may include first information related to resource allocation for a first block acknowledgment (BA) frame transmitted by a station (STA) to the first type AP. The first type AP may transmit, to the STA, a physical protocol data unit (PPDU) including data for the STA and the first information. The first type AP may receive, from the STA, the first BA frame on the basis of the first information.

Abstract: One example according to the present specification relates to a scheme for transmitting a PPDU in a wireless LAN (WLAN) system. A transmission STA can determine whether both a first channel and a second channel are idle. The transmission STA can configure backoff count values associated with the first channel and the second channel. The transmission STA can reduce the backoff count values on the basis of the first channel and the second channel. The transmission STA can transmit an NGV PPDU on the basis of the backoff count values.
