Abstract: A handheld electronic device may include a microphone for receiving voice commands, a speaker for providing audio feedback, a display for providing visual output and receiving touch input, and a motion sensor for receiving gesture input. The handheld electronic device may include control circuitry that processes voice commands differently depending on the application running on the handheld electronic device and the icon being displayed on the display. The control circuitry may determine the location of the handheld electronic device and may provide content based on the location. For example, a remote control interface for controlling an external device may be displayed when the handheld electronic device approaches the external device. A head-mounted device may display virtual images based on the location of the handheld electronic device. The virtual images may include a live video feed from a video call, virtual images associated with voice commands, or other virtual images.

Abstract: A process for sharing spectrum based on signal based shared access (SSA) includes measuring by a primary wireless system, the quality of a signal of interest (SOI) over a shared spectrum band. The process includes transmitting a signal quality indicator related to an associated action message from the primary wireless system to a second wireless system. The process also includes receiving spectrum usage information by the primary wireless system from the second wireless system. The process further includes determining by the primary wireless system whether the second wireless system complies with spectrum sharing band conditions between the primary wireless system and the second wireless system.
