Abstract: Proposed is a method and apparatus for receiving UL data in a wireless LAN system. Particularly, a transmission apparatus transmits an NSRP trigger frame to a reception apparatus. The transmission apparatus receives an NSR control frame from the reception apparatus in response to the NSRP trigger frame. The NSR control frame includes an NAV value. When the NAV value is 0, the transmission apparatus transmits a trigger frame to the reception apparatus. The transmission apparatus receives UL data from the reception apparatus on the basis of the trigger frame.

Abstract: The present specification relates to a method and a device for determination related to enhanced distributed channel access (EDCA). For example, it may be inappropriate for a STA to perform uplink communication based on EDCA. In this case, an AP and/or the STA can disable an EDCA function or operation. The present specification proposes various examples of a determination criterion and a determination method related to EDCA disabling.
