Introduction to 6G Technology
The development of 6G technology is a significant milestone in the field of mobile communications. Researchers in Korea have made a major breakthrough with the development of a technology platform that brings the 6G era closer. The Electronics and Telecommunications Research Institute (ETRI) has announced the completion of AI-based wireless access technology (AI-RAN), a core foundational technology for the 6G era. This technology has the potential to achieve transmission efficiencies up to 10 times higher than those of 5G, making it a significant improvement over current mobile communication systems.
AI-RAN Technology
AI-RAN technology is a key component of the 6G era, and it applies AI to wireless transmission, network control, and edge computing to reliably handle large volumes of data even in ultra-dense network environments. This technology performs various functions, including channel state analysis, cooperation and interference management between base stations, edge traffic prediction and distribution, and delay minimization. The AI-RAN structure learns the state of wireless networks and independently adjusts to the optimal connection environment, ensuring stable communication quality even in ultra-high-density environments. The Neural Receiver technology, a next-generation reception technology, is a significant achievement of this research, which enables AI to directly restore wireless signals and immediately detect errors.
Experimental Results
Experimental results have shown that AI-based receivers in millimeter-wave environments have demonstrated superior performance compared to existing methods. The results include an approximately 18% improvement in data recovery accuracy, an approximately 15% improvement in channel prediction accuracy, and a 30% reduction in data loss rate. These results demonstrate that AI technology can dramatically improve communication efficiency even in wireless transmission environments. The success of AI-RAN technology is a significant step towards the realization of AI-Native 6G networks, which will enable AI to autonomously control and optimize the communication system.
Standardization and Future Plans
ETRI is strengthening its global 6G technology competitiveness by leading the standardization of technologies such as "AI/ML-based wireless interface" and "AI-based mobility management" in 3GPP, an international standardization organization. The institute has achieved outstanding results in the fields of research, technology, and standardization, including applying for 119 domestic and international patents and contributing 68 technology articles to 3GPP. ETRI plans to develop this achievement into a "Self-Evolving RAN" technology, which will enable AI to independently learn and evolve to maintain optimal communication performance. The institute will also continue to strengthen its capabilities to ensure Korea leads the way in AI network technology in the 6G era through AI-RAN Alliance activities, international joint research, and participation in global exhibitions.
Conclusion
The development of AI-RAN technology is a significant milestone in the field of mobile communications, and it has the potential to revolutionize the way we communicate. With its ability to achieve transmission efficiencies up to 10 times higher than those of 5G, AI-RAN technology is a major breakthrough in the development of 6G technology. ETRI’s commitment to standardization and future plans will ensure that Korea remains at the forefront of AI network technology in the 6G era. As the world moves towards the adoption of 6G technology, the development of AI-RAN technology will play a critical role in shaping the future of mobile communications.
