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: Certain aspects of the present disclosure provide methods and apparatus for adaptive antenna tuning. One example method for wireless communications generally includes determining a first channel characteristic associated with a first component carrier and an antenna in an apparatus; determining a second channel characteristic associated with a second component carrier and the antenna; and controlling a tuner coupled to the antenna based on at least one of the first channel characteristic or the second channel characteristic. For certain aspects, the tuner is controlled according to predetermined characteristics of the tuner, where the predetermined characteristics of the tuner are independent from predetermined characteristics of the antenna.
