  • Publication number: 20260155854
    Abstract: A first transmission power level based on a radio frequency exposure limit and a second transmission power level based on the first transmission power level and a probability of detection of a body by a body proximity sensor are determined, where it is ensured that an average usage of the first and second transmission power levels over time does not exceed the transmission power limit, determined based on radio frequency exposure limits. A transmission power gain is determined based on a difference between the first and second transmission power level based on the probability of detection, and a false alarm rate of the body by the body proximity sensor. The transmission power gain may be used as a performance indicator to select from multiple first and second transmission power gains. First and second transmission power gains corresponding to the selected transmission power gain may be stored and applied during transmission.
