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.

Abstract: Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

Abstract: Proposed are a method and an apparatus for changing a primary link belonging to an NSTR link pair through an ML element in a WLAN system Specifically, a receiving MLD receives an ML element from a transmitting MLD via a first link. The receiving MLD decodes the ML element. The first link is a primary link, and a second link is a non-primary link. The first and second links are link pairs operating as NSTRs. The ML element contains a common information field. The common information field includes first and second subfields. The first subfield includes information that the primary link is changed from the first link to the second link. The second subfield includes information on a time when the primary link is changed from the first link to the second link.
