The wireless packet scheduler is a key element of HSDPA that determines the overall behavior of the system. We propose a novel QoS-guaranteed wireless packet scheduling scheme for a mixture of real-time and non-real-time services in HSDPA networks. By implementing a periodic non-work-conserving scheduling scheme, in contrast to the traditional work-conserving schemes, our scheme can enhance channel usage efficiency while satisfying the QoS requirements of real-time users. Simulation results of comparison with other popular scheduling schemes indicate that our scheduling algorithm can be used to maximize the channel capacity with guaranteed QoS provision for real-time users.
