Abstract: 5G completed the first phase of functional standardization work, and the independent and non- independent networking NR standards have been finished. In the evolving 5G process, satellite communication technology provides a powerful solution for 90%of regional and application scenarios.Achieving 5Gsatellite architecture requires further standardization to fully exploit the advantages of multiple networks, making the entire system adaptable, flexible and dynamic. China has already reached the world’s advanced level in the key technologies of ground 5G. But China has just started in the standardization of 5Gsatellite technology. Starting from the standardization process of 5Gsatellites at nation and abroad, this paper focuses on the content and direction of 5G satellite standardization. This paper proposes organizational and development suggestions that are compatible with China's development status.The research content mainly includes the development process of 5G satellite standardization at home and abroad, the current 5G satellite standardization content and development trend, domestic organization form and development suggestions.

Key words: satellite standardization of 5G, NR, development suggestions
