The collaboration is developing future 6G AI-AI proof-of-concept systems, which will then be tested using selected use cases and real-world environmental scenarios. These on-air validation tests will be conducted both in the lab and outdoors to better simulate actual network performance. SKT, NTT, DOCOMO, and Nokia will cooperate to improve the AI ​​model's performance using data generated from real networks or through simulation. This will be critical in developing AI training models for an industry-leading AI-AI solution.
