Abstract
In this paper, we consider algorithmic approaches for effectively providing data services for mobile users with different levels of priorities in a DS-CDMA system. The priority level of a user is specified by a factor that is a weighting on the instantaneous data throughput of the user. We define the weighted instantaneous aggregate data throughput (or the weighted channel efficiency) and use it to characterize the performance of the prioritized data service. Our prioritized data service is implemented so that the weighted instantaneous aggregate data throughput is maximized via efficient power and spreading gain allocation. We obtain properties of an optimal allocation that provides the maximum weighted instantaneous aggregate data throughput. Using these properties, we develop an efficient algorithm for computing the optimal power and spreading gain allocation. We also propose two suboptimal algorithms that are very fast and simple to implement.
