Power control in a spread-spectrum communication system takes place by determining origination power of a traffic channel based on a number of active demodulators and pilot channel signal quality (610). Once origination transmit power is determined and call origination takes place, the transmit power is reduced at a first rate when a time is less than a time for all active demodulators to be established (615), otherwise the transmit power is reduced at a second rate (621). After all active demodulators have been acquired power control takes place by receiving a Power Measurement Report Message (PMRM) or a Pilot Strength Measurement Message (PSMM), determining, a signal quality metric existing at the remote unit based on the PMRM or PSMM, and adjusting transmit power based on the signal quality metric (645).

[ What is claimed is:] [1.] A method of power control in a communication system, the method comprising the steps of:communicating, via a first base station, to a remote unit on a first channel at a first power level;determining a signal quality metric of the first channel, wherein the signal quality metric is based on a ratio of the first channel power to that of a total received power and additionally based on a number of active rays to the remote unit generated by a plurality of base stations due to soft/softer handoff; andoriginating a call, via the first base station, on a second channel at a second power level, said second power level different from said first power level and based on the signal quality metric.
