Abstract
A method for TA-SAR optimization with an antenna tuner is provided. The antenna tuner has multiple tuner states. An instant SAR level that is higher than a threshold SAR level is calculated. A suitable tuner among the multiple tuner states is determined based on the instant SAR level. The tuner is switched to the suitable tuner state to transmit signals with the TX power level corresponding to the suitable tuner state.
Claims20
A method for time-averaged specific absorption rate (TA-SAR) optimization with an antenna tuner, wherein the antenna tuner has multiple tuner states, comprising:
- calculating an instant SAR level that is higher than a threshold SAR level;
- determining a suitable tuner state among the multiple tuner states based on the instant SAR level;
- and
- switching the tuner to the suitable tuner state to transmit signals with the TX power level corresponding to the suitable tuner state.
An electronic device, comprising:
- an antenna tuner, having multiple tuner states;
- and
- an RF modem, electrically connected to the antenna tuner, and configured to obtain a first table;
- wherein the RF modem calculates an instant SAR level that is higher than a threshold SAR level, determines a suitable tuner state among the multiple tuner states based on the instant SAR level, and sends a setting command related to the suitable tuner state to the antenna tuner;
- wherein the antenna tuner is switched to the suitable tuner state to transmit signals with the TX power level corresponding to the suitable tuner state according to the setting command.
