    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.
