Abstract

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).
