Abstract: Proposed herein is a method and device for receiving a WUR discovery frame in a wireless LAN system. More specifically, a station (STA) receives a WUR discovery element from an access point (AP). The STA receives the WUR discovery frame from a neighbor AP based on the WUR discovery element. The WUR discovery element includes AP list information. The AP list information includes information on a WUR discovery period. The WUR discovery frame is received during the WUR discovery period.

Abstract: A method performed in a wireless local area network (LAN) system is presented. Particularly, a first type access point (AP) #1 can receive a trigger frame from a second type AP. The first type AP #1 can transmit a null data packet (NDP) request frame to a first station (STA). The first type AP #1 can receive a first NDP frame from the first STA, and receive a second NDP frame from a second STA. The first type AP #1 can receive a feedback request frame from the second type AP. The first type AP #1 can transmit an NDP feedback frame to the second type AP on the basis of the first and second NDP frames.

Abstract: In the wireless LAN system, the station STA receives a frame and updates a corresponding Inter-BSS Network Allocation Vector (NAV) or Intra-BSS NAV according to whether the frame is an Inter-BSS (Basic Service Set) frame or an Intra-BSS frame. If the received frame cannot be distinguished from the Inter-BSS frame or the Intra-BSS frame, it updates the Inter-NAV, and after receiving the frame that cannot be distinguished from the Inter-BSS frame or the Intra-BSS frame, it receives the CF-End frame, and then the corresponding NAV is reset.

Abstract: Provided is a method and device for transceiving a frame in a wireless LAN system. Particularly, an AP transmits a first frame to a first STA via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a DL transmission and a UL transmission. The relationship between the first STA and the second STA is a hidden node. A PHY header of the first frame includes channel status information of the second band. An NAV of the first STA is set up on the basis of the channel status information.

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.
