Abstract
A system and method for switching between power control modes is implemented in a communication system having two or more power control modes for providing a power increase for a transmitted signal. The system and method determine whether performance of the communication system is within nominal bounds. If the performance of the communication system is within nominal bounds, a first mode of power control is selected for controlling transmitter power. If the performance of the communication system is not within the nominal bounds, a second mode of power control for controlling a transmitter is selected.
Claims20
A system for selecting one of a plurality of power control modes for a transmitter operating in a communication system, the communication system having a first mode of providing one or more power increases of a first amount and a second mode for providing one or more power increases of a second amount, comprising:
- means for determining whether performance of the communication system is within nominal bounds;
- means for selecting the first mode of power control for controlling transmitter power if the performance of the communication system is within nominal bounds;
- and
- means for continuously selecting the second mode of power for controlling the transmitter to maintain the communication system performance within the nominal bounds, if the performance of the communication system is not within nominal bounds;
- wherein the first mode is a tracking mode of power control and the second mode is a burst mode of power control, and
- wherein the burst mode of power control provides a greater increase in power than the tracking control of power control when system performance is below a threshold level.
A method of selecting one of a plurality of power control modes for a transmitter operating in a communication system, the communication system having a first mode for providing one or more power increases of a first amount and a second mode for providing one or more power increases of a second amount, the method comprising the steps of:
- determining whether performance of the communication system is within nominal bounds;
- selecting the first mode of power control for controlling transmitter power if the performance of the communication system is within nominal bounds;
- and
- continually selecting the second mode of power control for controlling the transmitter to maintain the communication system performance within the nominal bounds, if he performance of the communication system is not within nominal bounds;
- wherein the first mode is a tracking mode of power control and the second mode is a burst mode of power control, and
- wherein the burst mode of power control provides a greater increase in power than the tracking control of power control when system performance is below a threshold level.
