Abstract: Techniques and apparatus for tuning a wireless data transmission system in an electronic device. One example method includes receiving a measured impedance value corresponding to a current user interaction state with respect to one or more antennas of a mobile device; determining a user interaction stability state of the mobile device based on the measured impedance value and a set of historical impedance values; classifying the current user interaction state based at least on the measured impedance value and a plurality of impedance values from the set of historical impedance values; and tuning the one or more antennas based on the classified current user interaction state and the determined user interaction stability state of the mobile device.

Abstract: An antenna tuning circuit achieves robust performance in a closed loop antenna tuning system due to the addition of protection circuits. In one instance, a protection circuit to detect an overload condition based on a threshold value may be included in the antenna tuning circuit. The antenna tuning circuit also includes a protection state register coupled to the protection circuit to store one or more safe states of operation to which the circuit is restored in response to detecting the overload condition. The antenna tuning circuit also includes a bus interface coupled to the protection state register to transmit an indication of a state of operation of the circuit to an external tuning control device coupled to the circuit and to receive pre-defined protection actions from the external tuning control device in response to the indication of the state of operation.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for improved machine learning. Impedance information for a wireless transmitter of a device is determined, and impedance change information is generated based on a difference between the impedance information and prior impedance information for the wireless transmitter. An off-body characteristic is generated based on processing the impedance change information using a trained machine learning model, where the off-body characteristic indicates a probability that the device was off-body when the impedance information was determined.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for complying with radio frequency (RF) exposure limits via device positioning relative to a human body. An example method of wireless communication includes obtaining first information associated with one or more sensors. The method further includes obtaining second information associated with a mode of using the wireless device. The method further includes determining a position of the wireless device relative to a human body based at least in part on the first information and the second information. The method further includes transmitting a signal at a transmit power in compliance with an RF exposure limit based at least in part on the determined position of the wireless device.

Abstract: A method for wireless communication by a user equipment (UE) includes measuring changes in impedance at an antenna. The method also includes estimating an amount of power reflected from the antenna based on the measured changes in impedance at the antenna, in order to obtain an estimated amount of radiated power. The method further includes dynamically increasing a transmit power of the UE, based on the estimated amount of radiated power, up to a limit.
