LTE网络下载速率优化实践

The Download Rate Optimization Practice of LTE

目前,中国联通LTE网络主要承载的业务为数据业务,切实保障LTE网络质量,提高LTE网络用户感知,提升LTE下载速率十分重要。笔者从影响LTE下载速率的各种原因入手,探讨了LTE网络下载速率的优化流程。影响LTE下载速率的因素主要有RSRP、SINR、RB调度数、模三干扰、误块率以及传输误码率等,通过逐步的优化工作,提高用户下载速率,进而提升中国联通客户感知度。

At present,the main business of China Unicom LTE network is data service.It is very important to ensure the quality of LTE network,improve the users'perception of LTE network and enhance the download rate of LTE.Starting from various reasons that affect LTE download rate,the author discusses the optimization process of LTE network download rate.The main factors affecting LTE download rate are RSRP,SINR,RB scheduling number,analog-to-digital interference,block error rate and transmission error rate.Through gradual optimization,users'download rate will be improved,and then the customer perception of China Unicom will be enhanced.
