[Abstract]:ITU has officially started the 5G standard research work. 5G has entered the critical stage of key technology breakthrough and standard formation. It is necessary to carry out 5G candidate frequency band research as soon as possible. In this paper, the propagation characteristics of millimeter wave in 5G key candidate frequency band and link budget are analyzed and studied. The interference coexistence between 5G candidate frequency band IMT and satellite system is analyzed and studied comprehensively. Some valuable calculation and simulation results are provided, which is of great reference value to the design and deployment of 5G wireless communication system in the future. This paper first introduces the research status of interference coexistence between wireless communication systems at home and abroad, which is of great significance to the further study of 5G interference coexistence. Secondly, the compatibility of 5 G key candidate band IMT and satellite system is analyzed. Thirdly, based on the study of millimeter-wave propagation characteristics, the coexistence of 28GHz band IMT and satellite fixed service interference is studied, specifically, based on the satellite actual orbit position and coverage information, The lumped interference of IMT base station antenna from 0 掳to 90 掳is studied by lumped interference method. Fourthly, based on the existing technical parameters, the coexistence of interference between IMT system and inter-satellite services in the 25.25-27.5GHz band in Beijing-Tianjin-Hebei region is studied. The conclusions obtained in this paper can provide useful value for the design and practical application of 5G in the future. In this paper, the coexistence of 5G candidate band IMT and satellite system interference is analyzed and studied, which provides useful value for the simulation design of 5G wireless communication system and the deployment of 5G base station in the future.
