摘　　要：无线通信利用电磁波承载信息实现远距离通信,摆脱线缆束缚,推动世界经济发展和社会进步。无线通信发展范式是与无线通信技术演进相关的自然规律、理论基础和实践规范。回顾了已有无线通信发展范式的适用范围、关键技术等,并指出无论被动适应还是主动利用无线环境的发展范式均受到“空谱墙”的制约,对抗无线扰动的能力还处于“靠天吃饭”的阶段,没有从根本上改变受限于无线环境的状况,制约了无线通信服务能力的提升。针对这一瓶颈问题,提出“改造定制无线环境”的无线通信发展新范式,并探索了新范式的理论和智能超表面(RIS)赋能的实践规范。金梁,战略支援部队信息工程大学教授、博士生导师;主要研究领域为移动通信及无线内生安全;先后主持承担国家“863”计划重大项目、国家科技重大专项、国家自然科学基金、国家重点研发计划项目、装发预研等10余项,主持制定移动通信安全领域国家技术标准、国家军用标准各1项;获得国家科技进步奖一等奖1项、国家级教学成果奖一等奖1项、军队科技进步奖一等奖2项;发表论文150余篇,申请发明专利30余项,出版译著1部。Wireless communication uses electromagnetic waves to carry information to achieve long-distance communication,which gets rid of the shackles of cables and promotes world economic development and social progress.The wireless communication development para⁃digm is a natural law,theoretical basis,and practical specification related to the evolution of wireless communication technology.The scope of application and key technologies of the existing wireless communication development paradigms are reviewed,and it is pointed out that development paradigms for both passive adaptation and active use of the wireless environment are restricted by the“space spectrum wall”.The ability of existing wireless communication development paradigms to resist wireless disturbances is still at the stage of“depending on heaven for food”,and the situation limited by the wireless environment has not been fundamentally changed,which restricts the improve⁃ment of wireless communication service capabilities.In response to this bottleneck problem,a new paradigm of wireless communication de⁃velopment by“reforming and customizing wireless environments”is proposed.The theoretical exploration of the new paradigm and practi⁃cal specifications based on the reconfigurable intelligent surface(RIS)are introduced.
