Abstract: Provided are a method and device for receiving data in a wireless LAN system. Particularly, an STA transmits an operating band negotiation request frame to an AP by means of a first band supported by first and second RFs. The STA receives an operating band negotiation response frame from the AP by means of the first band as a response to the operating band negotiation request frame. The STA changes the first band supported by the second RF into a second band on the basis of the operating band negotiation request frame and the operating band negotiation response frame. The STA receives first data from the AP by means of the first band supported by the first RF and the second band supported by the second RF. The first data is transmitted by means of a multi-band in which the first band and the second band are combined.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. 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 PPDUs to a reception device via the multi-band on the basis of the result of the channel sensing. In the multi-hand, a first band and a second band are combined. The first band includes a first primary channel. The second band includes a second primary channel. The channel sensing is performed on the basis of a first CW value which is set in common for the first and second bands. If transmission of some PPDUs allocated to the second band of the PPDUs fails, the first CW value is increased.

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.
