An improved power control method for WCDMA cellular mobile systems

With the 3G coming into the actualization stage, people are no longer satisfied with the voice service of wireless communication. As an improvement, they require the wireless network to provide many more services including multimedia service. In this paper, a summary of the current two typical methods for power control: conventional power control and dynamic resource scheduling was given; both were designed for the WCDMA system that supports multimedia service and QoS. Based on their strong points as well as shortcomings, an improved method, probability-dynamic resource scheduling, was proposed, aiming to achieve a better balance between power consumption and BER performance.
