Abstract
A method for power control, including determining a need in a transmitter to perform a first output power update and then a second output power update. The method includes selecting a control mode for the first output power update and a control mode for the second output power update prior to performing the first output power update. The control modes are selected from a closed loop mode and an open loop mode, and the selection is based on a function of a current output power, a power to be applied at the first output power update, and a power to be applied at the second output power update. The method includes performing the first output power update using the first control mode, and then performing the second output power update using the second control mode, without measuring a power level applied responsively to performing the first output power update.
