NTT DOCOMO, in collaboration with NTT Corporation, Nokia, and SK Telecom, has achieved a milestone in 6G research by conducting Japan’s first indoor test of AI-optimized 6G technology in the 4.8 GHz band. The test demonstrated an 18% improvement in communication throughput compared to traditional methods. The trial leveraged AI to enhance baseband processing, optimizing performance for indoor radio wave propagation environments.
The test utilized Nokia-developed AI-based baseband transmission and reception processing. This technology replaced conventional reference signals between transmitters and receivers with AI-driven processes that handle channel estimation and signal detection in a single step. This approach not only improved transmission efficiency but also allowed for adaptive modulation schemes suited to varying propagation conditions. These findings indicate the potential for widespread application across diverse wireless use cases.
DOCOMO aims to continue collaborating with global partners and vendors to advance 6G research, with a focus on standardization and commercialization. Some results from the trial will be presented at the NTT R&D Forum 2024 – IOWN INTEGRAL starting November 25.
• First indoor 6G test in Japan using AI, conducted in the 4.8 GHz band.
• AI replaced traditional reference signals, enhancing transmission efficiency.
• Results confirmed up to 18% improvement in communication speeds.
• Technology optimizes modulation schemes for diverse propagation conditions.
