摘要： Example wireless feedback control systems disclosed herein include a receiver to receive a first measurement of a target system via a first wireless link. Disclosed example systems also include a neural network to predict a value of a state of the target system at a future time relative to a prior time associated with the first measurement, the neural network to predict the value of the state of the target system based on the first measurement and a prior sequence of values of a control signal previously generated to control the target system during a time interval between the prior time and the future time, and the neural network to output the predicted value of the state of the target system to a controller. Disclosed example systems further include a transmitter to transmit a new value of the control signal to the target system via a second wireless link.

摘要： Example predictive wireless feedback control systems disclosed herein include a receiver to receive measurements of a controlled system via a first wireless link. Disclosed example systems also include an observer to output estimated values of states of the controlled system based on a state space model that is updated based on the measurements. Disclosed example system further include a predictor to predict future values of the states of the controlled system based on the estimated values of the states, a first latency of the first wireless link and an upper limit of a second latency associated with a second wireless link that is to communicate values of a control signal to an actuator associated with the controlled system. In disclosed examples, the predictor is to output the predicted future values of the states to a controller that is to determine the control signal.

摘要： This disclosure describes systems, methods, and devices related to providing dynamic quality of service (QoS) to multiple devices using QoS-aware controls. A device may identify first state information from a first device using the network and second state information from a second device using the network; generate, using machine learning, based on the first state information, a first dynamic QoS to be applied to the first device at a first time, and, based on the second state information, a second dynamic QoS to be applied to the second device at the first time; allocate a first allocation of resources to the first device, based on the first dynamic QoS, at the first time; and allocate a second allocation of resources to the second device, based on the second dynamic QoS, at the first time.

摘要： In one example, a transmitter wireless communication device may be configured to encode k data packets into n encoded packets according to a Network Coding (NC) scheme, wherein k is equal to or greater than two, and wherein n is greater than k. For example, the transmitter wireless communication device may be configured to transmit the n encoded packets over a plurality of wireless communication resources, for example, by transmitting at least one first encoded packet over a first wireless communication resource and transmitting at least one second encoded packet over a second wireless communication resource. For example, a receiver wireless communication device may be configured to determine the k data packets, for example, by decoding at least k received encoded packets out of the n encoded packets according to the NC scheme.

摘要： This disclosure describes systems, methods, and devices related to wireless time sensitive networking. A device may identify, using an 802.3 protocol stack, an 802.3 frame received from a second device using a wired Ethernet connection, and extract, using the 802.3 protocol stack, a redundancy tag from the 802.3 frame, the redundancy tag including a sequence number. The device may generate, using an 802.11 protocol stack, an 802.11 frame with a subnetwork access protocol (SNAP) field, the SNAP field including an organizationally unique identifier (OUI) and the sequence number, the OUT including an indication of an Ethertype protocol. The device may send the 802.11 frame using a wireless connection.

摘要： For example, an apparatus may be configured to cause an Access Point (AP) to transmit a frame over a wireless communication channel, the frame including a field according to a first Physical layer Protocol Data Unit (PPDU) version decodable by a wireless communication (STA) of a first STA type, the field configured to indicate to the STA of the first STA type that the wireless communication channel is to be reserved for a reserved duration; and to communicate a low-overhead PPDU with a STA of a second STA type over the wireless communication channel during a Synchronized Transmit Opportunity (S-TxOP), wherein the S-TxOP is within the reserved duration, wherein the low-overhead PPDU is configured according to a second PPDU version decodable by the STA of the second STA type, the low overhead PPDU including a low-overhead preamble excluding one or more preamble fields of the first PPDU version.

摘要： This disclosure describes systems, methods, and devices related to fast transition Wi-Fi roaming operations. A device may generate, during a first association of the device to a first access point, a request to authenticate the device to a second access point; send, during the first association, the request to authenticate; receive, during the first association, a response indicating that the device is authenticated to the second access point; generate, during the first association, a reassociation request to the second access point; determine that a time between sending the request to authenticate and generating the reassociation request is less than a threshold time; send, based on the determination that the time is less than the threshold time, the reassociation request to the second access point; and receive a reassociation response indicative of a second association of the device to the second access point.

摘要： This disclosure describes systems, methods, and devices related to using redundant frames for time-sensitive networking (TSN). A device may identify an Ethernet frame including a redundancy tag and an Internet Protocol (IP) packet; generate, based on the Ethernet frame, a first Wi-Fi frame including the redundancy tag and a sub-network access protocol (SNAP) header after an 802.11 medium access control (MAC) header and prior to the redundancy tag, the first Wi-Fi frame further including a first encapsulation of the IP packet; generate, based on the Ethernet frame, a second Wi-Fi frame including the redundancy tag and the SNAP header after the 802.11 MAC header and prior to the redundancy tag, the second Wi-Fi frame further including a second encapsulation of the IP packet; transmit the first Wi-Fi frame using a first Wi-Fi communication link; and transmit the second Wi-Fi frame using a second Wi-Fi communication link.

摘要： In order to better and more easily identify candidate APs and/or channels, an AP can transmit frames announcing its capabilities in a channel where it is not serving. For example, if an AP is operating in channel 1 and has created a Basic Service Set ID (BSSID) in that channel, it is permitted to transmit frames announcing its capabilities in another channel, for example channel 3, where another AP may or may not be operating.
