The mobile communication device may then measure the impedance value of a characteristic circuit, such as the antenna or the power amplifier. Responsive to determining that the measured impedance value differs from a pre-defined base impedance value by more than a certain threshold value, the mobile communication device may retrieve, from a memory, a set of envelope tracking (ET) parameter values corresponding to the current state of the communication device and the measured impedance value. The mobile communication device may calculate, using the retrieved ET parameter values, a target supply voltage to be applied to the power amplifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adapting envelope tracking parameters to operating conditions of mobile communication device","description":"A mobile communication device may use sensor data to identify the current device state based on sensor data, device parameter values and/or device usage data.
