  • Patent number: 10838058
    Abstract: Architecture and techniques for identifying types of objects based upon disruption of signal strength of millimeter-wave (mmW) transmitted signals caused by objects interfering with or blocking transmitted signals within a wireless communication network. In particular, types of objects may be identified based upon drops in signal strength due to objects moving between a transmission point and a receiving device. Based on factors including one or more of a size of an object, materials that make up the object, etc., the object causes a drop in received signal strength, thereby causing a change in a pattern of received signal strength. The changed pattern may be compared with base patterns that are correlated with a type or identity of an object in order to identify the object.

  • Publication number: 20200322836
    Abstract: A location for application processing is selected based on latency measurements associated with a mobile network. Instead of performing application processing at a predetermined location within a network, the application processing for an application is located within the network based on latencies measured within the network as well as other considerations. For instance, the determination of the location within the network can be based on latency measurements, target latency specifications of an application, the availability of computing resources at a location, and the like. A latency aware routing controller selects one or more locations to perform application processing. The locations may include computing resources located at or near the wireless base station (BS), between the base station and other locations within the network, at the core network, at the Internet, and/or at other locations to provide applications with the computing resources to perform the application processing.

  • Patent number: 10743259
    Abstract: Wireless transition timers associated with wireless transition states are adaptively controlled in relation to use of applications by user equipment (UE). A UE can include a transition management component (TMC) that can adaptively control wireless transition timers associated with wireless states based on application type, session content, or other factors. The TMC monitors data flow associated with an application and, for a current or subsequent communication session, controls the length of wireless transition timers and switching between wireless states to improve UE, application, and/or network performance while maintaining QOE for the user. The TMC can access a timer look-up table that maps wireless transition timers to application type, content type, user behavior, or other factors. The TMC also can desirably control maintaining persistence or always-on connections by controlling switching between wireless states using the adapted wireless transition timers.

  • Patent number: 10728009
    Abstract: Techniques for detecting and/or mitigating interference in a wireless network are discussed herein. An environment may include a base station in communication with one or more user equipment (UE) and one or more microwave backhaul transceivers. In some examples, the base station may and transceivers may communicate using frequencies in the same band (e.g., a millimeter frequency band). A geometry of devices in an environment can be determined. Further, interference can be detected based on a flexible portion of a transmission or a source identifier that can be included in a transmission. In some examples, the microwave backhaul transceivers may communicate via a same or similar millimeter frequency resources. Wireless resource(s) can be selected or otherwise determined for one or more components of the network to mitigate interference in the network.

  • Publication number: 20200186964
    Abstract: The use of unmanned aerial vehicle (UAV) communication cells in conjunction with MEC nodes may provide low-latency processing of vehicle movement data to generate vehicle guidance instructions for vehicles. Vehicle movement data of vehicles are received at a base station of a wireless carrier network from a UAV communication cell that is attached to the base station. The base station sends the vehicle movement data to a mobile edge computing (MEC) node that directly communicates with the base station so that the MEC node generates vehicle guidance instructions. The vehicle guidance instructions are then received by the base station from the MEC node. In turn, the base station sends the vehicle guidance instructions to the UAV communication cell for broadcasting to vehicles.

  • Patent number: 10616734
    Abstract: Techniques are described herein for conducting traffic and road operations using unmanned aerial vehicle (UAV) assisted vehicle-to-everything (V2X) communications. The UAVs can be deployed at various locations and can be operatively connected to a cell site, a mobile edge computing (MEC) server, and/or a V2X sensor. The UAVs, upon detecting an oncoming vehicle from a target location traveling towards one or more autonomous vehicles (AVs), can directly communicate with the one or more AVs to alert the AVs of the approaching oncoming vehicle. If the UAVs cannot communicate with the AVs, the UAVs can handover messages to other UAVs that can communicate with the AVs. The UAVs can also transport messages to a cell site and/or a V2X sensor to broadcast messages to the one or more AVs. Cell sites can also transmit messages to broadcast the messages to the AVs within respective coverage areas.

  • Patent number: 10588035
    Abstract: Coverage and usage-based limitations to a wireless communications network can be estimated by monitoring network performance during a periods in which the network is relatively busy and relatively non-busy. For example, differences in distributions of bit error rates for calls in such time periods can be used to assess whether network limitations are associated with reduced-coverage zones or are usage-based. Such estimates can be used to target specific network features that limit network performance.

  • Publication number: 20190394700
    Abstract: A terminal communicatively connectable with a relay terminal can establish a first connection with the relay terminal via a communications interface. The terminal can determine status information associated with at least one of the terminal or the first connection; and transmit, via the communications interface, the status information. In some examples, a relay terminal can receive, from a remote terminal, the status information. The relay terminal can determine that a reliability of the first connection does not satisfy a predetermined criterion based at least in part on the status information and, in response, cause the remote terminal to establish a connection with an additional relay terminal different from the relay terminal. Some examples include a sidelink connection between the remote terminal and the relay terminal.
