摘　　要：为保障第五代移动通信(5G)技术在我国的研发与测试,保护3.5 GHz频段上卫星固定业务(FSS)的正常工作,运用最新5G系统参数和国际电信联盟(ITU)相关建议书提供的仿真方法,开展了3.5 GHz频段上5G系统基站与FSS系统的共存研究。结果表明,3.5 GHz频段上5G系统基站对FSS地球站同频干扰较大,难以实现两系统同频共存,邻频部署时可通过一定的措施实现两系统共存。For the guarantee of the development and testing of the fifth generation mobile communication （5G） technology in our country, and the protection of the normal work of the 3.5 GHz band fixed satellite service （FSS）, the latest 5G system parameters and the simulation method provided by International Telecommunication Union （ITU） proposals are used to carry out the research of the coexistence of 3.5 GHz band 5G system base station with the FSS system in this paper. The results show that the 5G system base stations（BSs） has a large co-channel interference to FSS earth station at 3.5 GHz band, which makes it difficult to realize the coexistence of two systems at the same frequency, and the coexistence of two systems can be realized by some measures when the adjacent frequency is deployed.
