Abstract
Briefly, a method an apparatus to control a power of a transmitter during received slot duration is provided. A power control module set the transmitter to transmit in a targeted power level base on a command received from the slot. The power control module may set an input signal to a first level and may gradually vary the level of the input signal to be substantially equal to its original level and to adjust a gain of the transmitter to transmit at the targeted power level.
Claims19
A method comprising:
- at a time slot of receiving a data block which includes power control information, controlling a power level of a transmitted signal based on the power control information received with the data block by varying an input signal level and a gain of the transmitted signal, wherein varying the input signal level includes:
- sampling a feedback signal of the transmitted signal;
- storing a first sample of the feedback signal;
- comparing the first sample to other samples of the feedback signal;
- advancing the level of the input signal toward its initial level when the first sample is substantially equal to one of the other samples;
- and generating a control signal based on the results of the comparing.

An apparatus comprising:
- a step attenuator to set at a time slot of receiving a data block a level of an input signal of a transmitted signal based on a target power value provided by the data block;
- a transmitter to transmit a signal at the target power value;
- and
- a power control module to advance the level of the input signal to its initial level based on a feedback signal, to provide a control signal to adjust a gain of the transmitter and to adaptively learn a gain transfer function of the transmitter by applying to the control signal prestored coefficients of the gain transfer function.
