Abstract: Provided is a method and device for transceiving a frame in a wireless Local Area Network (LAN) system. Particularly, an Access Point (AP) transmits a first frame to a first station (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 Downlink (DL) transmission and a Uplink (UL) transmission. The relationship between the first STA and the second STA is a hidden node. A Physical (PHY) header of the first frame includes channel status information of the second band. A Network Allocation Vector (NAV) of the first STA is set up on the basis of the channel status information.

Abstract: In a wireless local area network system, a transmitting multi-link device (MLD) includes at least one transmitting station (STA). The transmitting STA generates a multi-link (ML) element and transmits the ML element. The ML element includes a common information field and information related to each transmitting STA. The information related to each transmitting STA includes a first link identifier (ID) field and a first link information field that includes information related to a transmitting STA operating in a link related to the first link field. The first link information field includes information commonly related to all transmitting STAs included in the transmitting MLD based on the first link ID field having a first value.

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.
