1. A device comprising a processor configured to:
monitor a transmit power for each of a plurality of transmitters;
determine a transmit power reduction to be applied to the plurality of transmitters based on a total simultaneous transmit power of the plurality of transmitters exceeding a threshold;
define a respective amount of the transmit power reduction to be applied to each transmitter of the plurality of transmitters based on one or more parameters; and
apply the respective amount of the transmit power reduction to each transmitter of the plurality of transmitters,
wherein each transmitter of the plurality of transmitters is additionally configured to apply its respective amount of the transmit power reduction to a plurality of time-averaging (TA)-specific absorption rate (SAR) parameters, and
wherein the TA-SAR parameters comprise a lower threshold, a dynamic power reduction (DPR) ON value, and a DPR OFF value for a respective transmitter of the plurality of transmitters.
