    Abstract: One embodiment according to the present specification relates to a method for transmitting, from a first link, information for setting a NAV in a second link. When transmission STA performs communication through a second link, the transmission STA can transmit, through a first link, information for setting the NAV for the second link in another STA. Particularly, the transmission STA can receive, from the second reception STA, a second frame through the second link. The transmission STA can transmit, to a first reception STA, a first frame through the first link during the reception of the second frame. The first frame can include information for setting the NAV for the second link. The first reception STA can set the NAV for the second link on the basis of the first frame.

    Abstract: A method and apparatus for transmitting a PPDU on the basis of S-TDMA in a wireless LAN system are presented. In particular, an AP generates a PPDU, and transmits the PPDU to a first STA and a second STA. When a PPDU further comprises a third signal field, the third signal field comprises information about S-TDMA. The information about S-TDMA comprises STDMA indication information indicating that S-TDMA can be carried out, first symbol offset information about a first data field, and second symbol offset information about a second data field. The S-TDMA indication information comprises information indicating that the first and second data fields are assigned to a first RU. The first data field is transmitted from the first RU during a first symbol determined on the basis of the first symbol offset information. The second data field is transmitted from the first RU during a second symbol determined on the basis of the second symbol offset information.

    Abstract: A method and device for transmitting data in a wireless LAN system are provided. Particularly, a transmission device receives configuration information relating to a multi-band. The transmission device performs channel sensing with respect to the multi-band. The transmission device transmits data to a reception device via the multi-band on the basis of the result of the channel sensing. A first band and a second band are combined in the multi-band. The first band comprises a first primary channel, and the second band comprises a second primary channel. The result of the channel sensing is obtained on the basis of whether or not the first primary channel is idle until a first BC value becomes 0 and whether or not the second primary channel is idle until a second BC value becomes 0. The first BC value is selected within a first CW configured with respect to the first primary channel. The second BC value is selected within a second CW configured with respect to the second primary channel.

    Abstract: An AP and a STA can perform a PHY-level HARQ operation in a wireless local area network system, and the AP can transmit resource allocation information about a PHY-level feedback frame to be transmitted by a plurality of STAs. The AP can receive a plurality of HARQ feedback frames from a plurality of STAs. The plurality of HARQ feedback frames are PHY layer signals. The resource allocation information can include information related to a tone set and a symbol from which transmission of the plurality of HARQ feedback frames are started.
