Abstract:
1. A method, comprising: comparing a total transmit power of a plurality of power-controlled channels with a maximum power level, wherein the plurality of power-controlled channels comprise control channels and data channels configured for parallel control and data transmission in an uplink subframe; looking up an initial power backoff value to be subtracted from the maximum power level based at least in part on power-frequency profile parameters of the allocated control channels when the total transmit power exceeds the maximum power level; iterating the power backoff value and power-scaling until a change in the power backoff value is less than a predefined threshold, an iterated power backoff value being based at least in part on iterated power-scaling, and wherein iterating the power backoff value is based at least in part on a priority of channels in the plurality of power-controlled channels; and adjusting a transmit power of one or more channels in the plurality of power-controlled channels based on a result of iterating the power backoff value.
