A method is described for Wi-Fi sensing. The method is carried out by a networking device configured to operate as a station (STA) and includes at least one processor configured to execute instructions. The STA is associated with an original access point (AP) of an original basic service set (BSS) to establish an original association between the STA and the original AP. The STA and the original AP have an original communication link and an original sensing link established therebetween, the original communication link being established for data transmissions and the original sensing link being established for sensing transmissions. A transition management request identifying a preferred communication link between the STA and a preferred AP of a preferred BSS different than the original communication link with the original AP is received. Further, transmission of a transition preference indicating a preference to preserve the original sensing link is caused.

A station (STA) receives, via a channel, an overlapping basic service set (OBSS) physical layer protocol data unit (PPDU) comprising an indication of whether the OBSS PPDU contains latency sensitive (LS) traffic or whether pre-emption of the OBSS PPDU is allowed. The STA accesses the channel, to transmit a PPDU, based on the indication. Accessing the channel to transmit the PPDU based on the first indication may comprise accessing the channel to transmit the PPDU without consideration of overlap of the PPDU with the OBSS PPDU, based on the indication indicating that the OBSS PPDU does not contain LS traffic or that pre-emption of the OBSS PPDU is allowed.

An access point (AP) may enable and manage non-primary channel access (NPCA) with a station (STA). The AP and the STA may each specify various switching rules for triggering channel switch from a primary channel to a backup NPCA primary channel for NPCA operation, including rules regarding switching delays by which a switch may need to perform and rules regarding whether a primary channel is occupied by an overlapping basic service set (BSS). The AP and the STA may also exchange various frames that provide a capability indication regarding support for NPCA operation as well as one or more parameters and rules regarding the NPCA operation.

Described herein are devices, systems, methods, and processes for coordinating transmission opportunities (TXOPs) in a wireless network with multi-access point coordination (MAPC) and multi-link device (MLD) features. An MAPC coordinator in the network may coordinate TXOPs for multiple network devices in a coordination group. Some of these network devices can utilize multi-link operation (MLO), establishing multiple simultaneous links with client devices over the same or different frequency bands. The MAPC coordinator may receive data about the MLD status and buffer status of each basic service set (BSS) and / or each network device in the network. The MAPC coordinator can also receive data about the buffer status of client devices. Based on the data, the MAPC coordinator may make decisions about which MLD links are likely to be utilized and their associated TXOPs, optimizing network performance and efficiency.

A method is provided in which an AP of a MLD AP device may decide to include all out-of-link BSS parameters updates in a beacon frame (beacon). A flag is included in the beacon frame to indicate that all updates are included in the beacon frame and thus the client device that receives the beacon frame should not send probe request frames (probe requests) to obtain these updates. Thus, a non-AP MLD that receives a beacon frame with the above indication and that has all critical BSS parameters corresponding to the Change Sequence Number (CSN) that preceded the updates indicated by the AP, should not send probe requests to obtain the updated parameters. The number of bits to assign to the complete BSS Update Report Indication flag may vary depending on the number of updates to be reported.
