Abstract: Time Sensitive Networking (TSN) Quality of Service (QoS) in overlapped administrative domains may be provided. A first Access Point (AP) may detect at least a second AP in a Co-Channel Interference (CCI) range. A micro-transaction auction between the first AP and at least the second AP may be established, and the first AP may provide compensation to second AP to acquire an agreement, from the second AP, to forgo transmitting during an upcoming service period. Next, the first AP may schedule transmissions for the service period and then transmit in the service period without interference from the second AP.

Abstract: Systems, methods, and computer-readable media for controlling link selection and aggregation across multiple wireless networks based on a location of a mobile device. A location of a mobile device in a physical environment can be identified. At least portions of the physical environment can be in wireless range of a first wireless network and a second wireless network. Whether to access network services through either or both the first wireless network and the second wireless network can be determined based on the location of the mobile device in the physical environment. Further, a first interface at the mobile device to the first wireless network and a second interface at the mobile device to the second wireless network can be selectively toggled according to whether it is determined to access the network services through either or both the first wireless network and the second wireless network based on the location.

Abstract: A method comprising: at a multi-link device (MLD) configured for multi-link operation: establishing a first Internet Protocol (IP) stack of a first IP type and configured with a first IP address of the first IP type, wherein the first IP stack is associated to a first MLD media access control (MAC) address of a first station of the MLD; establishing a second IP stack of a second IP type and configured with a second IP address of the second IP type, wherein the second IP stack exists concurrently with the first IP stack and is associated to a second MLD MAC address of a second station of the MLD; and exchanging, with a peer MLD, IP traffic using one or more of (i) the first IP stack and the first MLD MAC address, and (ii) the second IP stack and the second MLD MAC address.

Abstract: This technology allows time synchronization in wireless networks with mobile stations. A wireless network controller transmits instructions to access points (“APs”) within the wireless network to monitor transmissions for time synchronization. One or more second APs observe fine time measurement (“FTM”) exchanges between a first AP and a mobile station. A particular second AP determines whether to perform a time synchronization with the first AP based on the detection of the FTM exchange or a determination that the station is moving toward the second AP. For time synchronization, the second AP determines the time that the first AP transmitted the FTM exchange and the time of transmission from the first AP to the second AP. The second AP synchronizes a second AP clock to the summation of the time of the transmission of the FTM exchange and the time of transmission from the first AP to the second AP.

Abstract: A reverse time synchronization may be performed between a sending device and a receiving device. Then a Time Error (TE) between the sending device and the receiving device may be determined based on the reverse time synchronization. A gate time on the receiving device may be scheduled based on the determined TE.

Abstract: Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.

Abstract: A host clock value may be provided to a client device. An Access Point (AP) may obtain a Timing Synchronization Function (TSF)-based time stamp. Next, the TSF-based time stamp may be placed in an Information Element (IE) that was intended to contain follow up information. The IE may then be transmitted.

Abstract: Best links for wireless clients may be provided. A computing device may receive, from a client device, a request to join a network. Then, in response to receiving the request to join the network, initial characteristics of the client device may be evaluated. Next, an initial plurality of links list may be provided to the client device in response to evaluating the initial characteristics of the client device. Subsequent characteristics of the client device may then be evaluated. An updated plurality of links list may be provided to the client device in response to evaluating the subsequent characteristics of the client device.

Abstract: Steering for location-assisted inter-set roaming, between different networks of the same or different types is provided by: identifying a first station connected to a first wireless network in an environment; identifying a direction of travel of the first station; identifying a second wireless network and a third wireless network as candidate roaming targets, based on the second wireless network and the third wireless network neighboring the first wireless network in the direction of travel, wherein the second wireless network and the third wireless network are different from the first wireless network; modifying a neighbor list for the first station to include an Access Point (AP) included in the third wireless network based on environmental knowledge; removing APs included in the second wireless network based on the environmental knowledge; and transmitting the neighbor list to the first station.

Abstract: Roaming Consortium Identifier (RCOI)-based handling of identity requirements may be provided. First, an access device may advertise an identifier. The identifier may identify a roaming federation and an identity type used by a service provider in order to provide service by the access device. Next, a request to associate with the access device may be received from a user device. The request may be compliant with the identity type advertised in the identifier. The user device may then be associated with the access device in response to receiving the request.
