Abstract

In this paper we study the fundamental problem of optimal transmission scheduling in a code-division multiple-access wireless system, in order to maximize the uplink system throughput, while satisfying the users' Quality of Service (QoS) requirements and maintaining the fairness among the various users, despite their different varying channel conditions. The corresponding problem is expressed as a weighted throughput maximization problem, where the weights are the control parameters that reflect the fairness constraints. It is shown that this optimization problem can be converted into a linear knapsack problem, where all the corresponding constraints are replaced by the users' power index capacities at some certain system power index. As a result the optimal scheduling policy is identified and the performance evaluation process reveals the advantages of the proposed policy over other existing scheduling schemes.
