Abstract
An approach for providing power control of a radio terminal is disclosed. A first control loop is performed according to a first set of signal parameters (e.g., signal-to-noise level) to adjust power level of the radio terminal based upon a received signal from the radio terminal. Further, a second control loop is performed according to a second set of signal parameters (e.g., raw bit error rate (BER)) to refine the power adjustment of the first control loop. The present invention has particular applicability to a point-to-multi-point or a point-to-point radio system.
