摘　　要：吞吐率是4G网络构成竞争优势的关键指标,影响吞吐率的因素众多,除网络质量关键因素外,吞吐率的差异取决于网络的调度算法,调度算法由UE和eNode B联合实现。UE完成信号监测后上报CQI和RI,eNode B根据调度算法输出TM、MCS、RB等信息,本文依据海量测试,分析得出了TD-LTE网络吞吐率遵循3大最优原则,为后续TD-LTE网络规划和优化提供理论依据。Throughput is a key indicator for competitive priority of 4G network. There are many factors that affect throughput. In addition to network quality, the throughput difference mainly depends on network scheduling algorithm which is jointly implemented by UEs and eNode B. UEs report CQI and R1 after signal monitoring, then eNode B output TM, MCS and RB information which are according to scheduling algorithm. Based on large amount of testing, this paper presents three major superior principles that TD- LTE network throughput should follow, and provides theoretical basis for subsequent TD-LTE network planning and optimization.
