NTT DOCOMO, INC., in collaboration with NTT Corporation, Nokia, and SK Telecom Co., Ltd., an international telecommunications operator, announced today that they have successfully conducted Japan's first indoor test of 6G wireless technology using radio waves enhanced by AI in the 4.8 GHz band.
They found that communication speeds can be improved by up to 18% compared to traditional indoor methods.

In preparation for the 6G era, DOCOMO, along with NTT, Nokia, and SK Telecom, utilized AI technology to enhance transmission and reception processing for different radio wave propagation environments. The test showed that communication performance can be enhanced by implementing AI-based baseband transmission and reception processing developed by Nokia. This technology optimizes modulation schemes based on the radio wave propagation environment, resulting in improved communication speeds.
By using AI for reception processes, the need for a known signal between the transmitter and receiver (reference signal) to estimate the propagation channel is eliminated. Instead, AI enables a series of reception processes from channel estimation to signal detection in one step, leading to higher transmission efficiency and faster communication speeds.

As this technology continues to evolve, it is expected to enhance communication quality across various wireless transmission scenarios by optimizing modulation and demodulation schemes for different propagation environments.
DOCOMO plans to conduct further tests with both domestic and international partners to accelerate 6G research and development (R&D), ultimately contributing to the global standardization and commercialization of 6G.
