[Purposes]This article aims to explore the application requirements and development trends of intelligent wireless environments and intelligent reconfigurable physical layers,and construct a comprehensive intelligent reconfigurable wireless communication model and architecture.[Methods]Firstly,incorporating various dimensions of wireless communication links such as physical layer parameters and wireless propagation environment into the scope of intelligent reconfigurability solves the problem of traditional communication technologies being unable to achieve higher dimensional control degrees due to hardware conditions and wireless environment limitations.Then,utilizing the perception data required for optimizing and customizing the physical layer and wireless environment,a fully reconfigurable structure is proposed that allows for dynamic switching between artificial intelligence algorithms based on different wireless environments and PHY parameters.[Findings]The simulation and analysis results show that the system is superior to the traditional method in terms of bit error rate and achievable rate.[Conclusions]By extending the idea of intelligent reconfigurability to various dimensions of wireless propagation environment and the entire communication link,an efficient full dimensional intelligent reconfigurable wireless communication system has been constructed,which can provide a theoretical basis and guidance for 6G mobile communication systems.
