Disclosed is a method of setting reverse link traffic and pilot transmit powers in a wireless communications system based on traffic channel activity in order to lower average total transmit power on the reverse link and optimize reverse link capacity. As traffic channel activity decreases, the traffic transmit power relative to the pilot transmit power, i.e., traffic-to-pilot ratio (TPR), should increase. Increasing TPR will produce lower pilot transmit powers and higher traffic transmit powers. Although higher traffic transmit powers are undesirable, the effect on average total transmit power is lessen because the traffic channel is not active all the time. By contrast, the pilot channel is always active and, thus, it is desirable to sacrifice some performance of channel estimation in order to lower average total transmit power.
