摘要：
数字孪生信道（DTC）是将无线信道从物理世界实时映射到数字世界，有望为第六代（6G）空口设计带来显著的性能提升。本文首先随着无线通信的演进取定义了信道孪生的五个演进等级，并从方法论、表征精度和数据类别等多维因素详细阐述了第五级——自主DTC。然后，我们对面向6G的完整DTC的需求和架构提供了详细见解。随后，展示了一个感知增强的实时信道预测平台及实验验证。最后，基于6G网络的愿景，我们探讨了未来DTC研究中的潜在应用和开放问题。
英文摘要：
Digital twin channel (DTC) is the real-time mapping of a wireless channel from the physical world to the digital world, which is expected to provide significant performance enhancements for the sixth-generation (6G) air-interface design. In this work, we first define five evolution levels of channel twins with the progression of wireless communication. The fifth level, autonomous DTC, is elaborated with multi-dimensional factors such as methodology, characterization precision, and data category. Then, we provide detailed insights into the requirements and architecture of a complete DTC for 6G. Subsequently, a sensing-enhanced real-time channel prediction platform and experimental validations are exhibited. Finally, drawing from the vision of the 6G network, we explore the potential applications and the open issues in future DTC research.
