前向分组数据业务中重传分组优先权的研究

Retransmission Priority Scheduling Algorithm for Forward Link Packet Data Service

该文研究了前向分组数据业务中应用的调度算法,在对常见的几种调度算法分析之后,提出一种新的调度算法。从理论和仿真两方面的性能分析显示,该算法通过适当改变重传分组的优先权,在保证满 足公平性准则的前提下,提高了系统吞吐量,降低了平均分组时延,改善了分组时延分布。

Forward link packet data service scheduling algorithm in mobile communication systems is researched in this paper. After analyzing a few kinds of familiar scheduling algorithms, a new scheduling algorithm is proposed. Both the theoretical analysis and the simulation results shows that this algorithm takes on several advantages. On the premise of satisfying the fairness criteria, it can increase the system throughput and decrease the average packet delay.
