Abstract: In a wireless local area network system, a station (STA) can transmit a first physical protocol data unit (PPDU) including a link adaptation control field. The link adaptation control field can include a bit indicating whether the link adaptation control field includes information related to low-latency traffic. The low-latency traffic can require a latency of less than or equal to a threshold value. The STA can be allocated resources for the low-latency traffic. The STA can transmit a second PPDU including the low-latency traffic through the resources.

Abstract: In a wireless local area network system, a receiving device may receive a Block Acknowledgment Request (BAR) frame including information related to a link for which an ACK is requested, and transmit a Block ACK (BA) frame on the basis of the BAR frame. The receiving device is a Multi-Link Device (MLD), which supports communication over multiple links. Each link of the multiple links can be configured based on 2.4 GHz band, 5 GHz band, and/or 6 GHz band defined in a conventional wireless local area network system.

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: The present specification relates to a high-efficiency wireless LAN standard operating in a new band. A reception station (STA) according to one embodiment of the present specification can carry out a step of receiving a discovery frame via a 2.4 GHz band or 5 GHz band from a first access point (AP), wherein the discovery frame includes information related to a second AP operating in a 6 GHz band. The reception STA can carry out an association procedure for the second AP operating in the 6 GHz band on the basis of the received information.

Abstract: Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

Abstract: An example according to the present specification relates to a method for performing low latency communication. A transmission STA and a reception STA may exchange a low latency communication request frame and a low latency communication response frame. The low latency communication request frame may include first information for performing the low latency communication. The first information may include at least one among information for requesting parameters for the low latency communication and information about traffic. In addition, the low latency communication response frame may include second information for performing the low latency communication. The second information may include information about the parameters for the low latency communication. The reception STA and the transmission STA may perform the low latency communication with the transmission STA on the basis of the first information and the second information.

Abstract: Proposed are a method and an apparatus for transmitting data in a wireless LAN system. Particularly, an AP transmits a PPDU to one STA. The AP transmits data to the one STA over a first NCCB band or a second NCCB band on the basis of the PPDU. The PPDU includes a first signal field and a second signal field. The first NCCB band is a 40 MHz or 60 MHz band generated by bonding a discontinuous 20 MHz band in an 80 MHz band. The second NCCB band is an 80 MHz, 100 MHz, 120 MHz, or 140 MHz band generated by bonding a discontinuous 20 MHz band in a 160 MHz band. The first signal field includes first information and second information. The first information is NCCB indication information on whether or not an NCCB can be performed. The second information is NCCB bandwidth information for a band to be used for transmitting the PPDU from the first NCCB band and the second NCCB band.

Abstract: A method by which an access point (AP) transmits a frame in a wireless LAN, according to one embodiment of the present disclosure, comprises: determining a wake-up radio (WUR) identifier (WID) for identifying a station (STA) and a group identifier (GID) for identifying an STA group to which the STA belongs, in a WUR mode; transmitting the WID and the GID through a primary connectivity radio (PCR) so as to allocate, to the STA, the determined WID and GID; and transmitting, based on the GID or the WID, a WUR frame for waking up a plurality of STAs including the STA operating in the WUR mode, wherein the AP can determine the GID by using a part of an ID space which can be used in the WUR, and determine the WID by using the remaining space excluding the partial ID space used for the GID.
