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.

Abstract: Proposed are a method and a device for transmitting data in a wireless LAN system. Specifically, a transmission device receives configuration information of a multi-band formed by aggregating first to third bands. The transmission device carries out channel sensing on the first to third bands. The transmission device transmits data to a receiving device on the basis of the result of the channel sensing. The first band comprises a first primary channel and a first secondary channel; the second band comprises a second primary channel and a second secondary channel; and the third band comprises a third primary channel and a third secondary channel.

Abstract: A method and an apparatus for transmitting a PPDU on the basis of an S-TDMA in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP receives, on the basis of the trigger frame, a first trigger-based frame from the first STA and a second trigger-based frame from the second STA. The trigger frame includes a common information field and a user information field. The common information field includes S-TDMA indication information enabling the S-TDMA to be performed. The user information field includes: allocation information on a first RU to which the first trigger-based frame and the second trigger-based frame are transmitted; first symbol offset information on the first trigger-based frame; and second symbol offset information on the second trigger-based frame.

Abstract: Proposed are a method and a device for receiving a PPDU on the basis of control information related to an operating channel in a wireless LAN system. Specifically, a reception STA receives control information from a transmission STA. The reception STA receives a PPDU from the transmission STA on the basis of the control information. The control information includes an EHT operation element and a UHR operation element. The EHT operation element includes a first channel bandwidth subfield, a first CCFS subfield, and a second CCFS subfield. The UHR operation element includes a second channel bandwidth subfield, a third CCFS subfield, and a fourth CCFS subfield.

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.
