    Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including low-latency traffic, first control information, and second control information. The low-latency traffic may be traffic which requires latency less than or equal to a threshold value. The first control information may include information associated with the size of the low-latency traffic stored in a buffer and the size of other traffic than the low-latency traffic, stored in the buffer. The second control information may include information associated with the low-latency traffic. The STA may be allocated a resource for the low-latency traffic. The STA may transmit a second PPDU through the resource.

    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 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: 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.

    Abstract: A method for uplink multi-user (UL MU) operation in a WLAN system according to an embodiment of the present specification comprises the steps of: receiving, by an access point (AP), a buffer state report frame used for the UL MU operation from a user STA associated with the AP, wherein the buffer state report frame includes bitmap information for a plurality of access categories for which the buffer state of the user STA is to be reported, and identification information for a number of traffic identifiers (TIDs) for at least one traffic being buffered by the user STA, wherein the identifier information is set based on a number of the plurality of access categories indicated by the bitmap information; and transmitting, by the AP, a trigger frame for triggering the UL MU operation from a plurality of user STAs.
