Abstract: This document describes techniques and devices for controlling radar transmissions within a licensed frequency band. In particular, a network is given control over whether or not a user equipment 110 transmits a radar signal within at least a portion of one or more licensed frequency bands associated with coverage of the network. With this control, the network can balance the use of the licensed frequency band for wireless communication operations and radar-based applications. The network can further control operations of the user equipment 110's radar system to control an amount of interference that is present within the licensed frequency band. With permission from the network via a radar grant message 524, the radar system can utilize frequencies within the licensed frequency band for radar-based applications, such as gesture recognition, presence detection, collision avoidance, and so forth.

Abstract: Methods, systems, and techniques for safely controlling wireless charging in the presence of a foreign object are presented. A method includes determining a power difference between a power transmitted by a wireless charger and a power received by an electronic device, determining a level of misalignment of the electronic device with respect to the wireless charger; estimating an amount of power difference due to the level of misalignment of the electronic device with respect to the wireless charger, adjusting a power difference threshold for the wireless charger based on the estimated amount of power difference, and controlling operation of the wireless charger based on the power difference and the adjusted power difference threshold.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for improving wireless charging. In some implementations, an electronic device determines a power demand of the electronic device. The electronic device includes a wireless power receiver including a wireless power receiving coil configured to receive power through inductive coupling with a wireless charge. The electronic device determines an operating voltage or operating frequency for the wireless charger based on the power demand of the electronic device. The electronic device sends, to the wireless charger, data indicating the operating voltage or operating frequency for the wireless charger.

Abstract: This document describes a passive adapter for wireless charging of an electronic device and associated methods and systems. The described passive adapter includes two coils connected by a capacitor and separated by a core material that prevents mutual coupling between the coils. These two coils may have differing sizes, such that one coil can size-match to a transmitter coil of an existing wireless charger and the second coil can size-match to a smaller (or larger) receiver coil in a wireless-power receiver to charge a battery of the wireless-power receiver. In aspects, these two coils may be separated by a distance that enables the passive adapter to act as a passive repeater by bridging a space between the transmitter coil and the receiver coil.
