Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU through a wide band from a transmission STA, and decodes the PPDU. The wide band is a 320/160+160 MHz band configured from a first band and a second band. When the first band is an 80 MHz band in which puncturing is performed in units of 20 MHz, the first band includes a first RU which is an aggregate of a 484RU and a 242RU. The second band is a 240 MHz band excluding the first band in the wide band, and includes a second RU which is an aggregate of three 996 RUs. The PPDU includes a control field and a data field. The data field is received via a first multi-RU which is an aggregate of the first and second RUs.

Abstract: In a wireless local area network system, a transmitting multi-link device (MLD) includes at least one transmitting station (STA). The transmitting STA generates a multi-link (ML) element and transmits the ML element. The ML element includes a common information field and information related to each transmitting STA. The information related to each transmitting STA includes a first link identifier (ID) field and a first link information field that includes information related to a transmitting STA operating in a link related to the first link field. The first link information field includes information commonly related to all transmitting STAs included in the transmitting MLD based on the first link ID field having a first value.

Abstract: Proposed is a method and apparatus for transmitting a C-OFDMA PPDU in a wireless LAN system. Specifically, a first AP transmits a C-OFDMA request frame to a second AP. The first AP receives a C-OFDMA response frame as a response to the COFDMA request frame from the second AP. The first AP transmits a first C-OFDMA PPDU to a first STA through a first channel. A second C-OFDMA PPDU is transmitted simultaneously together with the first PPDU through a second channel by the second AP. The C-OFDMA request frame includes first information indicating that using the second channel for the second AP is allowed. The first channel corresponds to a channel remaining after excluding a preamble-punctured channel from the entire channel, and the second channel corresponds to the preamble-punctured channel.

Abstract: A method and a device for transmitting data in a wireless LAN system are proposed. Specifically, an AP transmits a band switch announcement element through a first band supported by a first and a second RF. The AP changes the first band, supported by the second RF, to a second band on the basis of the band switch announcement element. The AP transmits first data to an STA through the first band supported by the first RF and the second band supported by the second RF. The first data is transmitted through a multiple band in which the first band and the second band are combined.

Abstract: The present specification proposes various technical characteristics that may be applied to a Wireless Local Area Network (WLAN) sensing. For example, the present specification proposes a procedure for WLAN sensing using multiple channels or multiple resources. The same or different channels and/or resources may be allocated to at least one wireless device performing the WLAN sensing. The at least one wireless device may perform measurement and signal transmission/reception processes that are included in the WLAN sensing by using the channel(s) and/or resource(s).

Abstract: In a wireless local area network (LAN) system, a first station (STA) may check the transfer failure of a first acknowledgement (ACK) signal for a first frame, the signal being received through a first link. The first STA may transmit report information related to the transfer failure of the first ACK signal to a second STA through a second link. Here, the report information may include identification information associated with the first link. The first STA may receive a second frame from the second STA through the first link. The first STA may transmit a second ACK signal for the second frame to the second STA through the first link on a narrowband.
