摘　　要：LTE系统引入下行频率选择性调度(Downlink Frequency Selective Scheduling,DL-FSS)用于尽可能避开衰落和干扰。抽取26个小区作为实验样本,通过指标分析和外场测试,研究下行频率选择性调度所带来的增益、资源投入以及影响,同时分析DL-FSS增益与激活用户数的关系。最后,针对研究结果提出了DL-FSS实施的建议以及总结梳理DL-FSS的增益原理。To avoid the fading and the interference mentioned above, in LTE system, the downlink frequency selective scheduling （DL-FSS） is introduced. Through the analysis of the key performance indicators and the field experiment, 26 cells are selected as the experimental samples to study the gain, cost and the influence of DL-FSS. At the same time, the relationship between the gain of DL-FSS and the number of active users are analyzed. Lastly, based on the analysis, the theory of the gain for DL-FSS is ob- tained. And the suggestions for the implement of DL-FSS are presented.
