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).

Abstract: Proposed are a method and a device for requesting partial information from APs within a transmission MLD in a WLAN system. Particularly, a reception MLD transmits a probe request frame to a transmission MLD via a first link. The reception MLD receives a probe response frame from the transmission MLD via the first link. When the partial information regarding the first link and the partial information regarding the second link are the same, the partial information regarding the second link is requested on the basis of the first request element, and a value of a first full information profile sub-field is set to 0.

Abstract: In a wireless local area network (wireless LAN) system, a transmitting STA can transmit, to a receiving STA, a grouping initiation frame for generating a group that is to perform sensing. The grouping initiation frame can include information related to a session identifier (ID) for a sensing session and to the number of transmission times of a sensing signal performed in the sensing session. The transmitting STA can receive a grouping response frame from the receiving STA. The receiving STA can be included in the group on the basis of the reception of the grouping response frame from the receiving STA within a threshold time preset from the transmission time of the grouping initiation frame. The sensing session can include at least one transmission opportunity (TXOP).

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.
