  • Patent number: 10931346
    Abstract: Methods, systems, computer-readable media, and apparatuses for beam management in a wireless communication system are presented. In some embodiments, a beam management subsystem in a moveable device selects a first antenna array and forms a first beam using the first antenna array for sending and receiving communication signals from a base station or other transceiver. A communication signal processing subsystem receives a first communication signal via the first beam. Upon movement of the moveable device, an inertial navigation subsystem determines a rotation vector associated with the movement. In response to the inertial navigation subsystem determining the rotation vector, the beam management subsystem selects a second antenna array using the rotation vector and forms a second beam directed toward the base station using the second antenna array. The communication signal processing subsystem can receive a second communication signal via the second beam.

  • Patent number: 10880382
    Abstract: An Internet of Things (IoT) pairing controller is described that enables an end-user to customize the implementation of IoT devices. The IoT pairing controller may receive a pairing request to pair a combination of active-active IoT devices or active-passive IoT devices. The IoT pairing controller may facilitate a selection of a pairing signal type that is used to pair the IoT devices, such as light, sound, heat, Bluetooth, and Wi-Fi. An end-user may select multiple pairing signal types, of which the IoT pairing controller may toggle between based on ambient environmental conditions, or as a failsafe confirmation of a “not sensed” pairing condition between IoT devices. The IoT pairing controller may associate client-defined statements with paired (i.e. sensed”) and unpaired (i.e. “not sensed”) pairing conditions of a pair of IoT devices.
