摘　　要：对邻频部署1.9 GHz频段TD-LTE与1.8 GHz/2.1 GHz频段LTE FDD系统间干扰情况进行研究,分析了干扰产生的机理和干扰场景,并将重点聚焦于基站与基站之间的干扰。结合确定性分析和仿真研究两种方法的干扰计算结果,给出了TD-LTE与LTE FDD系统间共存时基站设备和终端的射频技术指标与组网要求,并通过实验室测试和外场试验,对上述指标和组网要求进行验证,同时对现网新的干扰情况展开进一步分析,为4G系统国内使用和台站协同提供依据。The system interference of 1.9 GHz TD-LTE and 1.8 GHz/2.1 GHz LTE FDD was studied. Firstly, the interference mechanisms and scenarios were analyzed, which focused on the interference of BS-BS. Moreover, the radio frequency requirements of TD-LTE and LTE FDD coexistence were given as the result of deterministic analysis and simulation calculations. The RF requirements were finally verified through lab tests as well as extensive field tests. The conclusion provides meaningful reference of 4G system utilization and BS coordination in China.
