摘　　要：2019年10月31日,三大运营商启动5G商用,标志着我国正式进入5G时代。工信部发布的5G频段使用规划中包含3400~3600 MHz,与我国C波段卫星电视业务存在重叠。针对这个问题,从5G系统基站对C波段卫星电视接收系统的干扰案例展开分析,提出了避免同频、邻频干扰和保证卫星电视正常运营的对策。China has officially entered the 5 G era with the launch of the commercial ceremony of 5 G by three major operators on October 31,2019.The plan for 5 G band usage released by the Ministry of Industry and Information Technology includes 3400~3600 MHz,which overlaps with C-band satellite TV service.This paper analyzes the interference case of 5 G system base station on C-band satellite TV receiving system,and puts forward countermeasures to avoid interference of the same frequency and adjacent frequency and maintain the normal operation of satellite TV.
