Abstract: An electronic device may include wireless circuitry with radios and a front end module coupled to an antenna. The module may include a multi-stage, multi-cell reconfigurable power amplifier and a radio-frequency coupler shared by the radios and different radio access technologies (RATs). One or more processors may adjust a number of active stages of the power amplifier, circuitry and bias conditions of the active stages, tunable capacitors on the module, adjustable impedance matching networks on the module and/or in the power amplifier, and/or the coupler using a digital interface to place the module in different operating modes corresponding to different RATs, power levels, modulation schemes, and/or frequencies. Adjusting the operating mode may allow the power amplifier to be reconfigured to meet performance requirements while maximizing performance, meeting regulatory requirements, and minimizing power. Sharing the power amplifier and the coupler across radios and RATs may produce space and power savings.

Abstract: A method of unlocking a locked device includes receiving a device identifier over a wireless communication protocol, determining if the device identifier is associated with a list of trusted devices, transmitting a request to generate an acoustic signal over the wireless communication protocol based on the determination, receiving the acoustic signal as an audio sound generated external to the locked device, estimating a distance between a source of the audio sound and the locked device, and unlocking the locked device based on the estimation.

Abstract: Methods and systems include beamformed wireless communications to and from a user equipment electronic device. During operation of the user equipment electronic device, a change in slot aggregation is made. Using the aggregated slots, the user equipment electronic device and/or a wireless network utilize beam sweeps to determine a best beam pairing by repeating a shared channel in the aggregated slots with a beam sweep of multiple beams between the user equipment electronic device and the wireless network.

Abstract: Provided is a method for a user equipment (UE). The method includes determining a mobility state of the UE and performing reference signal measurement in a relaxation mode within at least one cell. The mobility state indicates mobility capability of the UE, and, the at least one cell is determined based on the mobility state.

Abstract: An electronic device includes a display having multiple regions of pixels. Each pixel includes a diode that emits light based on an amount of current through the diode and a transistor that controls the amount of current flowing through the diode. The electronic device includes driver-integrated circuitry that reduces hysteresis in a first transistor of a first pixel of a region of pixels, settles a threshold voltage of the first transistor, applies a test voltage to the first transistor, and senses a current across the first transistor. The electronic device includes processing circuitry that determines a predetermined voltage based on the current and a predetermined current-voltage relationship determined at an initial temperature, determines a voltage difference between the test voltage and the predetermined voltage, and applies the predetermined voltage and the voltage difference to a second transistor of a second pixel of the region of pixels.

Abstract: An electronic device may include processing circuitry configured to generate a first frame of image content and a second frame of image content. The second frame of image content is different from the first frame of image content. The electronic device may also include a display configured to display the first frame of image content at a first refresh rate. In response to receiving the second frame of image content, the electronic device may initially increase the refresh rate before tapering back to the first refresh rate while displaying the second frame of image content.
