Abstract: In a wireless local area network (WLAN) system, an access point (AP) may acquire, from an overlapping Basic Service Set (BSS), information related to a first allocation slot. The first allocation slot may be a time resource allocated for low-latency traffic of the OBSS, and the low-latency traffic may be a new type of traffic whose delay is set below a preconfigured threshold. The AP may transmit, to its associated STA, information related to a second allocation slot. The second allocation slot may be a time resource allocated for low-latency traffic of a BSS to which the AP belongs.

Abstract: The present specification proposes a technical feature related to a wake-up radio (WUR) STA. Specifically, proposed is an operation of updating a parameter related to an operation of a WUR mode. For example, the WUR STA may update a parameter related to the WUR mode by receiving an unsolicited frame from an AP while maintaining the WUR mode. The received frame may have a preset action type.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. Particularly, a transmission device receives configuration information relating to a multi-band. The transmission device performs channel sensing with respect to the multi-band. The transmission device transmits PPDUs to a reception device via the multi-band on the basis of the result of the channel sensing. In the multi-hand, a first band and a second band are combined. The first band includes a first primary channel. The second band includes a second primary channel. The channel sensing is performed on the basis of a first CW value which is set in common for the first and second bands. If transmission of some PPDUs allocated to the second band of the PPDUs fails, the first CW value is increased.

Abstract: Presented are a method by which a transmitting device performs channel switching between multi-links in a wireless local area network (LAN) system, and a device. Particularly, the method comprises the steps of: transmitting multi-link channel switching capability information to a receiving device, wherein the multi-link channel switching capability information includes information related to whether the transmitting device can perform channel changing between multi-link channels; transmitting a physical protocol data unit (PPDU) to the receiving device through a first link; transmitting a multi-link channel change signal to the receiving device through the first link; and transmitting the PPDU to the receiving device through a second link.

Abstract: In a wireless local area network system, a station (STA) generates a physical (PHY) protocol data unit (PPDU) including at least one subframe and information related to a subframe length, wherein the subframe may include a medium access control (MAC) protocol data unit (MPDU) and a padding bit. The length of the padding bit may be determined such that the length of the subframes is an integer multiple of a codeword length. The information related to the subframe length may be information on the number of codewords related to the subframe length. A step in which the STA transmits the PPDU may be comprised.

Abstract: According to various embodiments, a multi-link device (MLD) operating in multiple links including a first link may transmit, through a first station (STA) and to a first AP of an AP multi-link device, a request frame including an information field for requesting at least one element related to a second link. The multi-link device may receive at least one element related to the second link on the basis of the request frame.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: A method for a non-simultaneous transmit and receive (non-STR) device in a wireless local area network (LAN) is provided. The non-STR device may support a multi-link communication related to a first link and a second link. The non-STR device may determine whether to transmit a first physical protocol data unit (PPDU), PPDU, based on a channel access result on the first link and a channel access result on the second link. The non-STR device determines not to transmit the first PPDU through the first link and keeps the back-off counter of the first link at zero (0) when a back-off counter of the first link reaches zero (0) and a back-off counter of the second link does not reach zero (0).
