摘要 为确定在31.8 GHz^33.4 GHz频段为移动通信做出附加主要业务划分的可行性,对该频段第五代移动通信(5G)系统与无线电规则频率划分表中的主要业务无线电导航业务间的同频共存问题进行了系统间同频共存分析。采用最新的5G系统技术参数以及典型的无线电导航业务系统参数,通过仿真5G系统基站对无线电导航业务干扰功率密度,计算不同场景下5G系统基站对无线电导航业务的干扰概率。仿真结果表明,5G系统基站对无线电导航业务的同频干扰概率较大,因此,不建议在该频段引入移动通信系统。 In order to determine the feasibility of additional allocations to the mobile services on a primary basis in the frequency band 31.8~33.4 GHz,this paper analyzes the electromagnetic compatibility between the 5th Generation(5G)international mobile telecommunications system and radionavigation service,which is the principal services according to regulations on the radio frequency allocation in the frequency band.The paper simulates the aggregated interference from the 5G base stations,adopts the latest parameters and the typical characteristics of radionavigation service,and calculates the interference probability in different scenarios.The simulation results show that the 5G base stations may cause harmful interference to radionavigation service,so it is not recommended to introduce mobile communication system in this frequency band.
