摘　　要：目前LTE技术已成为整个移动通信网络演进的关键。TD-LTE基站作为3GPP无线接入网中唯一的网元,其射频性能直接影响到整个网络的覆盖、容量以及服务质量。首先对TD-LTE基站系统结构以及射频测试相关标准进行介绍;然后在研究TD-LTE基站射频一致性测试的基础上,深入分析了测试项的物理意义以及对实际网络部署的影响;最后提出基站射频一致性测试可行性方案,并对部分基站射频测试项实际测量结果进行评估。Currently, long term evolution（LTE） technology has become the key to the evolution of the whole mobile communication network. The radio frequency（RF） performance of TD-LTE base station, which is the only element in3 GPP radio access network, directly affects coverage, capacity and quality of service of the entire network. Firstly,the system architecture of TD-LTE base station and the related RF testing standard were introduced. Then, on the basis of the research of TD-LTE RF conformance testing, the physical meaning and influence on the actual network deployment of the test items were analyzed. Finally, a feasibility scheme of the base station RF conformance testing was proposed, and the results of some testing items were evaluated.
