Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

Abstract: One embodiment of the present specification relates to a method for performing low-latency communications. According to one embodiment, an interframe space (IFS) for low-latency data may be suggested. The interframe space for low-latency data may be set to be greater than PIFS and smaller than DIFS. On the basis of the interframe space for low-latency data, a reception STA may perform EDCA and transmit low-latency data to a transmission STA.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information related to low latency traffic. The low latency traffic may be traffic requiring a latency less than or equal to a threshold value. A resource for the low latency traffic may be allocated to the STA. The STA may transmit, via the resource, a second PPDU including the low latency traffic.

Abstract: In a wireless local area network system, a reception multi-link device (MLD) may not transmit a CTS frame, even if the reception multi-link device receives an RTS frame via a second link, in the case that an STA operating via a first link is a TXOP responder.

Abstract: In a wireless local area network system, a shared AP may receive an announcement frame and a data frame from a sharing AP for multi-AP transmission. In the present disclosure, the announcement frame may be transmitted in a broadcasting scheme. The data field of the announcement frame may include an identifier (ID) of the shared AP. The shared AP may receive a data frame from the sharing AP. In the present disclosure, a receiver address (RA) field of the data frame may include an address of the sharing AP. The shared AP may decode the data frame based on the address of the sharing AP included in the RA field of the data frame.

Abstract: In a wireless local area network system, a reception multi-link device (MLD) may not transmit a CTS frame, even if the reception multi-link device receives an RTS frame via a second link, in the case that an STA operating via a first link is a TXOP responder. In detail, the reception MLD may include at least one non-simultaneous transmit and receive (NSTR) link pair. A first STA affiliated with the MLD may determine to respond with the CTS frame to the RTS frame. The first STA does not respond with the CTS frame based on another STA being a transmission opportunity (TXOP) responder on another link.
