摘要
第六代移动通信（6G）将开启“智赋万物、智慧内生”的信息技术新时代，相应技术研究成为移动通信行业的新热潮；在我国已开展第五代移动通信（5G）大规模商用的背景下，明晰6G发展需求、把握6G发展态势、提出6G发展布局，对于加快推动数字经济发展、抢占未来国际竞争优势具有重要意义。本文从应用深度不够、需求覆盖不足、投入收益不高等角度凝练了5G发展遗留而有待6G攻克的问题，指出一些关键应用场景、未来军事应用等亟需6G赋能；全面梳理了发达国家和发展中大国的6G战略部署情况，阐明了6G商用继续赋能传统产业优化升级、6G关键核心技术将实现重大突破、6G网络安全将事关国家安全体系现代化等重大趋势。我国6G发展在研发投入、技术标准、开放生态、网络安全和隐私保护等方面面临突出挑战，需要运用新型举国体制以突破技术创新壁垒、以6G标准为目标方向来增强通信标准话语权、深化6G国际合作以构建开放共赢的全球产业生态、攻关6G核心技术以建立安全可控技术体系。相关态势研判与发展建议可为我国6G技术发展与创新应用提供理论启示和现实参考。
