6G Radio Technology Part II: Basic Radio Technologies

6G technology is expected to not only usher in the next wave of digital economic growth, but also drive far-reaching societal shifts in sustainability, digital equality, trust, and quality of life.

The evolution in basic radio technologies is the most fundamental aspect of the next-generation cellular systems having a direct impact on canonical system Key Performance Indicators (KPIs). Part 1 of the 6G Basic Radio Technologies white paper focused on the fundamental 6G designs at the air interface level.

Part 2 provides a comprehensive overview of various key aspects shaping the future of wireless communication systems, particularly focusing on the evolution toward 6G and beyond. It discusses cutting-edge concepts such as:

  • AI-Native Air Interface
  • Device power-saving techniques
  • Integration of radio technologies with distributed cloud and Artificial Intelligence (AI)
  • Green networks emphasizing sustainability
  • Advancements in mesh networking and Sidelink (SL) communication
  • Near Zero Energy (NZE) communication for Internet of Things (IoT)
  • Non-terrestrial networks like satellite systems
  • Extreme networking scenarios demanding Ultra-Reliable Low-Latency Communication (URLLC)
  • Seamless mobility solutions
  • The potential of User Equipment (UE) cooperative communications to enhance network performance

Each section delves into specific challenges, strategic methodologies, and research directions essential for realizing the transformative potential of these technologies. The narrative underscores the interdisciplinary nature of future wireless systems, intertwining technological innovation with environmental sustainability and user-centric design principles to shape the future landscape of connectivity.
