Traffic management of high-speed CDMA systems based on load prediction

Abstract

The cdma2000 1xEV-DO system has a probabilistic rate control on the reverse link, but a simple up/down command from the base station may make the reverse link unstable. In this paper, we propose and analyze an enhanced rate control that minimizes the traffic overload on the reverse link by predicting the noise rise and defining a new command for stable operation. It is shown that the proposed rate control has a much higher revere-link throughput than the conventional schemes.
