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: Disclosed is a method by which an operating station (STA) transmits a signal in a multiple user (MU) scheme in a wireless LAN (WLAN) system. In the present method, the STA configures a wireless frame, which includes a data field for data transmission and a signaling (SIG) field including control information, wherein the SIG field includes a SIG A field, which includes bandwidth information indicating the whole bandwidth having a bandwidth of 2n times that of 20 MHz, and a SIG B field, which includes user specific information. Here, the bandwidth information of the SIG A field additionally indicates whether the whole bandwidth includes one or more 20 MHz bands (null channel), which are not used in the data transmission.
