Abstract: A system and method for dynamic mesh network discovery is disclosed. In embodiments, the system assigns each network asset (e.g., unmanned or manned aircraft or like mobile nodes) a unique asset number. Each asset has a controller coupled to a datalink including antenna elements and a memory for storing an asset table. Each asset periodically broadcasts an asset status message including the asset number. When a status message is received, the receiving asset compares the received asset number to its own asset number. If the received asset number is higher (e.g., of lower priority) than its own asset number, the receiving asset establishes a bidirectional mesh network connection to the broadcasting asset. Assets on the receiving end of a network connection interrogate the establishing asset for its asset number, such that assets on both sides of the connection know the identity of the other and update their asset tables accordingly.

The method also includes modifying at a second RedBox, the modified data frames to re-form the STP control data frames.

Abstract: A message batching configuration may be determined for transmitting a message to recipients. The message batching configuration may include two or more message batches, a respective recipient count for each message batch, a respective time delay between each message batch, and a performance metric for evaluating the message. The message is transmitted in accordance with the message batching configuration. The transmission of subsequent message batches is halted when it is determined that the designated performance metric fails to meet a designated performance metric threshold.

Abstract: Event-driven Internet of Things (IoT) abstraction using rules is disclosed herein. In one embodiment, a network computing device that provides an IoT management (IoTM) service is communicatively coupled to an IoT device. The IoTM service receives multiple rules, each of which comprises an event identifier that identifies an event that the IoT device is capable of emitting, and an action identifier that identifies an action to be performed by the IoTM service (e.g., a command to be issued to the IoT device or an operation to be performed by the IoTM service). Upon receiving a first event emitted by the IoT device, the IoTM service identifies a first rule of the plurality of rules based on a first event identifier of the first rule that matches the first event. The IoTM service then executes a first action, wherein a first action identifier of the first rule identifies the first action.

Abstract: The disclosure relates to method and system for correcting a clock skew in a slave device using a precision time protocol (PTP). The method includes determining an uplink delay and a downlink delay, based on at least two packet transactions in the PTP protocol and conducted between the slave device and a master device within a pre-defined accumulator time window. The method further includes determining a change in the uplink/downlink delay with respect to a reference uplink/downlink delay. The reference uplink/downlink delay correspond to a first pre-defined accumulator time window at a start of the slave device, or to a last pre-defined accumulator time window during a previous correction of the clock skew. The method further includes correcting the clock skew upon determining the change in the uplink delay to be about same in magnitude as and to be in opposite direction to the change in the downlink delay.

Abstract: Voice data transmission with adaptive redundancy creates a voice data packet by packetizing the voice data payload and a number of redundant payloads selected from a set of previous voice data payloads. The voice data from the voice data payload is analysed to determine whether it is a critical or non-critical payload by classifying the received voice data as voiced or unvoiced. If at least a portion of the voice data is classified as unvoiced, the voice data payload is determined to be a critical payload. If it is a critical payload, then the voice data payload is added to the set of previous voice data payloads for inclusion as a redundant payload in subsequent voice data packets. The voice data packet is then forwarded for transmission over the network.

Abstract: A network device may receive, from a source device, an option request that includes a source address of the source device and a destination address of a destination device, wherein the network device is associated with an Internet protocol version 6 (IPv6) network. The network device may identify a map code that is associated with an address translation for traffic associated with the destination device and may determine, based on identifying the map code, a source prefix code and a destination prefix code for the address translation. The network device may determine a source IPv6 prefix and a destination IPv6 prefix for the address translation based on the source prefix code and the destination prefix code and may provide, to the source device, an option response to the option request to permit the source device to use the source IPv6 prefix and the destination IPv6 prefix for the traffic.

Abstract: Radio frequency signal boosters are provided herein. In certain embodiments, a signal booster system includes a signal booster that is proximately located to an outdoor base station antenna. Implementing the signal booster system in this manner can provide a number of advantages relative to a configuration in which the signal booster is far from a base station antenna. For example, a long cable connected from an indoor signal booster to an outdoor base station antenna can be several meters long, resulting in significant cable loss that degrades transmit power and/or receiver sensitivity.

Where the first hardware queue group corresponds to a network property of the data frame based on a first mapping relationship, the first hardware queue corresponds to a service type of the data frame based on a second mapping relationship, the first mapping relationship includes mappings from network properties to hardware queue groups, and the second mapping relationship includes mappings from a plurality of service types to a plurality of hardware queues in the hardware queue group corresponding to the network property of the data frame; and then, the interface circuit sends the data frame from the N hardware queues through a radio channel.

Abstract: Systems and methods for clock synchronization are disclosed in which a primary node generates special physical layer clock sync symbols from the output of a reference clock and inserts the clock sync symbols within a symbol stream to one or more secondary nodes. Upon receiving a symbol stream, a secondary node can extract the clock sync symbols from the stream to synchronize its local clock with the reference clock of the primary node. In particular, the clock sync symbols can be inserted into the symbol stream at any arbitrary symbol location, e.g., even between consecutive symbols of a symbol encoded data frame. The clock sync symbols can also replace some control symbols in the symbol stream, such as idle or comma symbols. Accordingly, the clock sync symbols can be inserted into a symbol stream at fixed intervals, irregular intervals, or at any arbitrary time for high resolution clock synchronization.

Abstract: Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a pseudorandom number sequence, or “PN sequence”) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

Abstract: Embodiments described herein relate to an envelope tracking system that uses a single-bit digital signal to encode an analog envelope tracking control signal, or envelope tracking signal for brevity. In certain embodiments, the envelope tracking system can estimate or measure the amplitude of the baseband signal. The envelope tracking system can further estimate the amplitude of the envelope of the RF signal. The system can convert the amplitude of the envelope signal to a single-bit digital signal, typically at a higher, oversample rate. The single-bit digital signal can be transmitted in, for example, a low-voltage differential signaling (LVDS) format, from a transceiver to an envelope tracker. An analog-to-digital converter (ADC or A/D) can convert the single-bit digital signal back to an analog envelope signal. Moreover, a driver can increase the power of the A/D output envelope signal to produce an envelope-tracking supply voltage for a power amplifier.

The controller is configured to verify the at least one message for use in determining vehicle action.

Abstract: In implementations of systems for session-based routing, a computing device implements a routing system to receive session data describing a session ID as a character sequence including non-embedded characters and at least one embedded character at a pre-determined index of the character sequence. The routing system extracts the at least one embedded character and determines a processing device configuration corresponding to the at least one embedded character from ledger data describing processing device configurations. The routing system maps the session data to a particular processing device based on the processing device configuration and the non-embedded characters of the character sequence.
