摘　　要：为推动5G在中频段的重耕,研究了中频段NR FDD系统与WCDMA系统在相同地理区域邻频共存时的系统间干扰造成的性能损失,分析了在不同功率参数、不同拓扑结构、AAS/NON-AAS 2种天线模型下,4个干扰场景的仿真结果。最后给出NR FDD系统与WCDMA系统共存建议以及共存措施。To promote the refarming of the medium frequency band of 5G,it studies the performance loss of NR FDD system and the WCDMA system caused by inter-symtem interference of coexistence in the adjacent channel and in the same geographical area.Four interference scenaries are simulated and analyzed from different power control parameters and topologies and antenna models of AAS and NON-AAS.Finally,the co-existence suggestions and countermeasures of NR FDD system and WCDMA system is proposed.
