Abstract: Proposed are a method and an apparatus for receiving a PPDU over a broadband in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband. The receiving STA decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes first and second SIG fields. The first SIG field includes information on a broadband bandwidth. The information on the broadband bandwidth consists of 3 bits or 4 bits.

Abstract: In a wireless local area network system, a station (STA) may transmit, to an access point (AP), low-latency queue capability information including information related to whether the STA supports a low-latency queue. The STA may receive, from the AP, low-latency queue operation information including information related to a low-latency queue activation condition. The present invention may include a step of allowing the STA to transmit a low-latency queue activation signal to the AP on the basis of the low-latency queue activation condition.

Abstract: Provided are a method and apparatus for receiving only complete information on other access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The probe request frame includes a frame body and a profile field of a second receiving station (STA). When a first receiving STA does not request complete information on the first link and requests complete information on the second link, the complete information on the second link is requested based on the profile field of the second receiving STA. The probe response frame does not include the complete information on the first link, and includes only the complete information on the second link.

Abstract: In a wireless local area network system, a receiving STA may receive a PPDU. The receiving STA may check information related to an STA identifier and/or information related to a hybrid automatic repeat request (HARQ) operation. The receiving STA may perform one of the HARQ operation and an automatic repeat request (ARQ) operation on the basis of at least one of the information related to the STA identifier and the information related to the HARQ operation.

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.

Abstract: A method for an STA for receiving a WUR frame in a WLAN, according to one embodiment of the present invention, comprises the steps of: receiving a WUR frame including a first portion of a TSF timer and an MIC value; calculating an MIC verification value on the basis of the first portion of the TSF timer and the TSF timer stored in the STA; and determining whether to discard the received WUR frame depending on whether the MIC value included in the WUR frame matches the calculated MIC verification value, wherein the first portion of the TSF timer included in the WUR frame is the 8-bits following the least significant N-bit in the TSF timer, and the STA may obtain a continuous 48-bit partial TSF timer value through the first portion of the TSF timer and a second portion of the TSF timer stored in the STA, and may calculate the MIC verification value on the basis of the obtained 48-bit partial TSF timer value.
