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.
