    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

    Abstract: This disclosure provides methods, devices and systems for communicating over multiple links, for example, indicating buffered units (BUs) per traffic identifier (TID) for transmission to multi-link devices (MLDs). One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method can be performed, for example, by a non-access point (non-AP) MLD. The non-AP MLD can receive an indication of an association identifier (AID) associated with the non-AP MLD, wherein the indication of the AID indicates whether an AP has BUs for the non-AP MLD, determine one or more links associated with one or more TIDs based on a mapping of a plurality of TIDs, including the one or more TIDs, to a plurality of links, including the one or more links, receive the BUs associated with the one or more TIDs from the AP on the determined links.

    Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.

    Abstract: This disclosure provides methods, components, devices, and systems that support context acquisition for seamless roaming. Some aspects more specifically relate to segmenting a packet number (PN) space into subsets that are dynamically assigned to access points (APs) associated with a station (STA). In some implementations, a first wireless device (such as a STA) may communicate with a second wireless device (such as a serving AP) using a first subset of user data context parameters (such as a group or segment of PNs) that correspond to a first index assigned to the second wireless device. If, for example, the first wireless device decides to roam to a third wireless device (such as a target AP), the first wireless device may transmit one or more packets to the third wireless device using a second subset of the user data context parameters assigned to the third wireless device.

    Abstract: This disclosure provides methods, components, devices and systems for transmission opportunity (TXOP) sharing and resource allocation mechanisms in systems involving multiple peer-to-peer (P2P) sessions. Some aspects more specifically relate to how such mechanisms can facilitate multi-station (STA) TXOP sharing or STA offloading in accordance with relative resource availabilities across a set of access points (APs), or any combination thereof. In some implementations, an AP can allocate respective portions of a resource unit (RU) allocation (during a shared TXOP of the AP) to respective P2P sessions at multiple respective STAs. Additionally, or alternatively, an AP can use transmit power control to facilitate simultaneous TXOP sharing across multiple STAs. Additionally, or alternatively, first AP can offload a STA to a second AP in accordance with relative resource availabilities at the first AP and the second AP. As such, devices may achieve greater scalability for high-density P2P session deployments.
