Use Case and Gap Analysis for Radio Quality Assurance

With the integration of advanced IoT and network-enabled robotics into daily life, ensuring stable quality of service (QoS) across the entire service area is paramount for the upcoming 6G. A primary challenge in providing stable QoS in end-to-end (E2E) communications is the variation in radio communication channel quality, particularly the Signal-to-Interference-plus-Noise (SINR). This research report addressed the challenge of maintaining stable radio communication quality. It outlines the motivation for radio quality assurance, analyzes anticipated 6G use cases, and discusses gaps, challenges, and promising technical approaches for the development of O-RAN. Key findings underscore the necessity of a user-centric RAN approach to achieve cost-effective and stable radio quality. This highlights the importance of a RAN adaptability to SINR variations caused by changes in user location. Additionally, the report identifies significant technological gaps, particularly in supporting advanced applications in robotics, mission-critical operations, and Unmanned Aerial Vehicles/Urban Air Mobility (UAV/UAM).
