Abstract： With the rapid development of 6G communication technology, the space-air-ground integrated network has become a research hotspot due to its capability of global seamless coverage. This paper systematically investigates the development trend of coding technologies in the 6G space-air-ground integrated network based on patent analysis, focusing on four major technical branches: Turbo codes, LDPC codes, Polar codes, and AI coding. By analyzing global patent data from 2016 to 2025, the paper reveals the trends in technological evolution, regional competitive landscape, and distribution of innovative entities. The findings show that South Korea leads in the number of patents, China has an advantage in Polar codes, and AI coding accounts for more than 50% of the patents but is still in the early stages of standardization. The paper also identifies key technological gaps such as high dynamic channel adaptation and space-ground collaborative optimization, providing strategic references for the development of 6G coding technologies and standard setting.
