NTT Docomo has successfully conducted an indoor test of 6G wireless technology using artificial intelligence (AI) in the 4.8 GHz band in Japan. The test, held in collaboration with NTT, Nokia and SK Telecom, yielded improvement in communication speeds of up to 18 percent compared to conventional methods used indoors.
The trial was aimed at advancing the development of 6G technology by leveraging AI to enhance transmission and reception processes across various radio wave propagation environments.
By employing AI-based baseband transmission techniques developed by Nokia, the team was able to optimise modulation schemes tailored to specific conditions, leading to more efficient communication.
This approach eliminates the need for traditional reference signals between transmitters and receivers. Instead, the AI-driven process integrates channel estimation and signal detection into a single step, resulting in improved transmission efficiency and faster communication speeds. These advancements are expected to enhance communication quality across a wide range of wireless applications.
NTT Docomo plans to continue its testing initiatives with both domestic and international partners. It aims to accelerate research and development in 6G technology while contributing to global standardisation efforts and commercialisation strategies.
