摘要

In this paper, we propose a distributed rate control scheme for throughput maximization and different QoS support of each user in the 3GPP WCDMA system using the variable spreading factor of physical channel specification. We focus on the uplink rather than downlink for the reason that the uplink resource is not used effectively by the multiple access. The base station transmits rate command bits and persistence value p considering current load and number of users with each transmission rate. And each mobile station performs persistence test and changes transmission rate. The performance of the proposed scheme is compared with other conventional method by simulation. The simulation results show the proposed scheme has the high throughput achievement and the support of proper differentiation according to use's QoS.
