Abstract :
In WCDMA system, rate assignment algorithm on the downlink for the data transmission is proposed. The optimization goal of the resource allocation strategy is choosing appropriate utility function. The utility function reflects a flexible tradeoff between total system throughput and fairness. The power is distributed through the control module and the scheduling module. The simulations show the performance of the algorithm.
