Abstract
An electronic device may include radios that transmit signals using antennas. Control circuitry may assign radio-frequency exposure (RFE) budgets to the radios. The control circuitry may classify and predict attributes of application data for transmission over the radios, may generate a per-radio data prediction based on the classified attributes, and may generate the RFE budgets based on the classified attributes. Each radio may transmit application data based on its data prediction and according to its RFE budget. A dynamic portion of the RFE budget may be reserved for control signaling. RFE planning in this way may ensure that the device optimally utilizes its RFE budget, increasing overall RFE during some time periods so sufficient transmit power is available, and ensuring that RFE is distributed across the radios depending on the amount and criticality of the data to be transmitted by each radio.
