摘要：
In this paper we study the packet scheduling of mixed traffic in UTRAN Long Term Evolution Downlink. A dynamic Packet Scheduling (PS) architecture with service classification, queue specific sorting and scheduling algorithms as well as frequency domain PS has been presented to differentiate scheduling of different traffic classes. Simulation results have been provided by using control data, Voice-over-IP (VoIP) and Best Effort (BE) traffic types. The results show that VoIP prioritizing is needed to keep the VoIP UEs satisfied. However, the strict prioritizing decreases the system spectral efficiency to around 70-80% of the pure BE spectral efficiency due to small VoIP packets.
