The present invention relates to a wireless communication method, and more particularly, to a backoff method and device in the slot-type channel access of a wireless LAN system. A method of performing channel access by means of a station (STA) in a wireless LAN system according to an embodiment of the present invention may include: receiving restricted access window (RAW) configuration information on the station STA from an access point (AP); performing a backoff process by using a second backoff function state for a channel access within the RAW; and performing a backoff process by using a first backoff function state when the RAW is ended. The station STA may maintain a plurality of backoff function states that include the first backoff function state used outside the RAW and the second backoff function state used within the RAW. |
