Abstract: The present invention relates to a wireless communication system. More particularly, a method and a device for restricted access window-based channel access in a WLAN system are disclosed. The method whereby a station (STA) performs channel access in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving restricted access window (RAW) cross-border transmission allowance (CBTA) information from an access point (AP) in case an RAW is allocated to the STA; and performing transmission by the STA on the basis of the RAW CBTA information. In case the RAW CBTA information is configured as a first value, transmission by the STA beyond the border of the RAW may be allowed.

Abstract: The present invention relates to a method for converting, by a station (STA), a non-traffic indication map (TIM) mode into a TIM mode and performing channel-accessing. According to the present invention, a station that does not receive a TIM or DTIM is to be switched so as to operate between a wakeup mode and a sleep mode for power saving. In order to set an efficient wakeup time, the STA may listen to beacon frame information from an AP and access a channel through information included in the beacon frame information.

Abstract: Proposed are a method and a device for configuring a spatial reuse field in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB PPDU to the transmission STA through a pre-configured frequency band. The trigger frame comprises a common information field and a special user information field. The common information field comprises first to fourth spatial reuse fields. The special user information field comprises fifth and sixth spatial reuse fields. When the pre-configured frequency band is a 20 MHz band, the first to fourth spatial reuse fields are configured by the value of the fifth spatial reuse field.
