This paper proposes for DS-CDMA cellular systems a forward-link power control scheme utilizing neighboring-cell pilot power in order to improve the quality of forward traffic channels and to increase traffic capacity. In this scheme, each mobile station measures pilot powers received from neighboring cells. Transmission power of the forward traffic channel is then controlled by base stations according to the pilot powers measured at the respective mobile station, and uniform service quality is provided to all channels. Simulation results show that the proposed scheme reduces outage and forced termination probabilities with a pilot power error of 1.5 dB, and increases capacity for the forced termination probability of 1% by 5% and 60% in the case of soft handover and hard handover
