摘要：
In the co-frequency coexistence problem between the ground 5G system and NGSO (non-geostationary Orbit) constellation system, the interference from the 5G system to NGSO satellites is a typical scenario. Due to the massive number of satellites in the NGSO satellite constellation system, the location, beam direction and beam coverage of satellites are constantly changing. There are issues that the interference calculation amount is large and the actual distribution of the 5G system is difficult to obtain. To address these issues, we analyze the system model and interference principle, put forward the method of 5G system radiation energy to reduce the calculation amount, and present the location analysis method of 5G system based on K-means clustering to reflect the actual distribution of 5G system. Based on this, the interference from the Taiyuan 5G system to the O3b system satellite constellation is simulated. Compared with the existing simulation methods, the proposed method has less computation and is more in line with the actual distribution characteristics of the specific urban 5G system.
