6G Lean Radio Access Network Architecture and Key Technologies

With the rapid development of technologies such as mobile internet, multi-access edge computing, and artificial intelligence, the 6G network is facing unprecedented challenges and opportunities. In the future, 6G will carry more diversified service requirements. If the protocol stack overlay method continues to be used, the functions of the 6G protocol stack will become more complex, making it difficult to adapt to the development needs of future networks. In response to this challenge, this paper proposes a lean Radio Access Network (RAN) architecture design scheme. This scheme integrates multiple similar or repetitive functions to achieve functional integration and optimization, thereby simplifying the protocol layer structure and sinking some control functions closer to the edge side. This design not only reduces the signaling process but also effectively reduces network complexity and improves data processing efficiency.
