KT announced on the 11th that it successfully demonstrated next-generation AI-based wireless transmission technology in partnership with Qualcomm, a global leader in wireless communications, and German telecommunications equipment maker Rohde & Schwarz.
The next-generation AI-based wireless transmission technology is an AI-based CSI (Channel State Information) compression technology being developed under Release 20 by 3GPP, the international standardization body. The technology uses AI to learn complex wireless environments between base stations and devices, dramatically improving the accuracy of channel state information transmitted from devices to base stations, ultimately enabling enhanced downlink speeds from base stations.
For this demonstration, KT and Qualcomm built a test environment integrating Qualcomm's next-generation Snapdragon mobile platform with built-in AI capabilities and Rohde & Schwarz's AI base station system (CMX500 OBT). KT enhanced the technology's completeness by applying AI models optimized for real communication environments, leveraging its 5G network operation experience and base station configuration data. The demonstration confirmed improved wireless channel state information accuracy and approximately 50% improvement in downlink performance.
The demonstration showed that AI can substantially improve wireless performance itself and validated the effectiveness of 3GPP standards-based AI-RAN (intelligent base station) technology in commercial network environments. Building on this demonstration, KT plans to continue strengthening cooperation with global big tech companies to lead 6G standardization while developing AI-based wireless technologies for the 6G era.
