  • Patent number: 10945171
    Abstract: Techniques are described for improving handover performance in the context of UEs incorporated into unmanned aerial vehicles (UAVs, a.k.a., drones). A database is constructed that relates locations in a three-dimensional flying space to handover information that may include optimum scanning directions, optimum handover parameters, and/or optimum target cells to be monitored for possible handover.

  • Patent number: 10578743
    Abstract: Systems and methods of determining a device position are described. GPS and cellular signals, in addition to VIO displacement are used to determine the device position via a loose or tight coupling algorithm. Both algorithms iteratively linearize base station position equations around an intermediate position that changes each iteration based on VIO displacement and solves the linearized solutions until convergence. The loose coupling algorithm uses the GPS fix as an initiation position, linearizing and solving using the base station equations only. The tight coupling algorithm linearizes both the base station and GPS position equations, using an arbitrary initial position. To account for multipath effects, the linearization and solution are performed for multiple random sets of measurements and the position with the smallest error metric is selected.

  • Publication number: 20200033849
    Abstract: Logic may signal capability and interference control between a base station and a user equipment in an aerial vehicle. Logic may receive capabilities information from a user device to indicate that the user device is part of an aerial vehicle (AV-UE). Logic may transmit a measurement configuration to establish a trigger event based on a height or other measurement to instruct the AV-UE to transmit, in response to detection of the trigger event, a measurement report to the base station comprising interference information for downlink communications. And logic may transmit capabilities information from a user device to indicate that the user device is part of an aerial vehicle (AV-UE) and receive a measurement configuration to establish a trigger event based on a height or other measurement to instruct the AV-UE to transmit, in response to detection of the trigger event, a measurement report to the base station.

  • Patent number: 10298674
    Abstract: At least three different techniques are presented that facilitate cluster formation in clusterable devices such as drones. The techniques facilitate power saving in the individual clusterable devise as well as for the entirety of the cluster. The first technique utilizes a NAN application based cluster formation decision. The second technique initiates a cluster grade merging evaluation based on a “merge allowed” field in a synchronization beacon set by the discovery engine. The third technique involves a discovery engine managing cluster formation with pre-set cluster grade information.

  • Patent number: 10049587
    Abstract: System and techniques for unmanned aerial vehicle navigation are described herein. A plurality of transmission beams may be established. Here, each beam in the plurality of transmission beams is a focused photonic propagation directed to a fixed geographic area and a travel route intersects the fixed geographic areas of the plurality of transmission beams. Cell entry may be received for a vehicle transceiver entering a geographic area for a transmission beam in the plurality of beams. Scrambling codes corresponding to the plurality of transmission beams may be provided to the vehicle. A course parameter, decodable by a scrambling code of the scrambling codes, may be transmitted to the vehicle via the plurality of transmission beams.

  • Publication number: 20180077551
    Abstract: Methods and apparatus relating to emergency response for IoT (Internet of Things) and/or M2M (Machine to Machine) devices are described. In an embodiment, one or more signals corresponding to an emergency application identifier are communicated. A receiving device enters an emergency mode of operation in response to detection of the one or more signals within a proximity of the receiving device. The emergency mode of operation causes the receiving device to perform one or more operations during a time period when the one or more signals are detectable. Other embodiments are also disclosed and claimed.
