Abstract
In this paper, we first introduce a new network paradigm, called cybertwin based network architecture for 6G, which consists a cloud-centric network architecture and a radio access network architecture. The cybertwin serves as communications assistant, network behavior logger, and digital asset owner. The proposed cloud-centric network architecture can allocate computing, caching, communications resources coordinately, support locator/identifier separation, provide some embed security properties, and support the data market for privacy data. The new radio access network architecture, which can fully decouple the control and data base stations and entirely separate uplink and downlink, significantly enhance the spectrum utilization, reduce the network energy consumption and improve the quality of user experience.
