Abstract

We propose a novel dynamic stepsize power control method to improve the performance of UMTS/WCDMA cellular systems. The proposed method utilizes dynamic step-size power control commands, received SIR/power, and mobile handset location assistance data. Furthermore, dynamic inter-operation between the power control, admission control, and handoff control is evolved to improve the convergence of the proposed power control mechanism. Based on the output of this interoperability, a multi-step transmit power edge setting is proposed. Finally, the performance of the proposed method has been evaluated by extensive simulations.
