摘要：
Third generation wireless communication systems will support multimedia, and W-CDMA will be the common air interface technology. Due to the interference limited nature of CDMA, power is the main resource of the network, and power control is a means of resource management. In this article, we introduce Dynamic Resource Scheduling (DRS) as a framework which employs power control for QoS provisioning of multimedia traffic in W-CDMA. In DRS, we propose the application of optimal power assignment to the W-CDMA architecture, and we also suggest several implementation strategies. A simulation model of the Japanese W-CDMA standard (ARIB) has been developed for performance evaluation. The DRS framework is shown to accommodate different service classes efficiently by optimal resource management. Quantitative advantages are proven in terms of gains in capacity, throughput, power saving and QoS stability.
