6G network will have the unprecedented connectivity performance and meet diverse use cases and user demands through the network architecture design that integrates multiple innovative technologies. However
the versatility and flexibility of 6G network will bring the significant challenges for the performance guarantees and the operational maintenance. By leveraging digital twin technology
the digital twin networks can be created. Combined with artificial intelligence and other data analytics techniques
the digital twin networks enable in-depth analysis of network data and prediction of future network behaviors. The performance of 6G networks is ensured and network operations and maintenance are empowered through the cooperation between virtuality and reality. Based on this
the integration of digital twin technology into 6G network was explored
analyzing demand scenarios
network architectures
key technologies
opportunities
and challenges
aiming to chart a development roadmap for digital twin technology enabled 6G network.
