Abstract
Methods and systems for assessing radio frequency (RF) exposure from a wireless device. An example apparatus generally includes at least one processor configured to determine a time-averaged radio frequency (RF) exposure measurement over a time window, comprising a number of time slots, accounting for a future time slot; determine a maximum allowed transmission power level for the future time slot based on a reduced power limit and the time-averaged RF exposure measurement, the reduced power limit being less than a transmission power limit for the time window; and set a transmission power level for the future time slot based on the maximum allowed transmission power level. The example apparatus also includes an interface configured to output one or more signals for transmission during the future time slot at the transmission power level.
