TD-LTE下行分组调度研究

摘要

In order to solve the limitations of classical packet scheduling framework in TD-LTE, the TD-LTE downlink packet scheduling was studied and a framework of downlink packet scheduling for TD-LTE is designed. The packet scheduling framework was built and three classic scheduling algorithms were simulated in this framework by OPNET. The simulation results show that the packet scheduling framework can be applied to scheduling algorithms with different purposes and verify the performances of throughput and fairness of these three scheduling algorithms.%为解决分组调度架构在TD-LTE中的使用局限性,研究了TD-LTE下行分组调度,并设计出适用于TD-LTE的下行分组调度架构.通过OPNET软件搭建该分组调度架构,对3种经典调度算法在该架构下的使用进行仿真.仿真结果表明,该分组调度架构适用于不同目的的调度算法.同时也验证了这3种调度算法在吞吐量和公平性方面的性能.
