As information and communication technology (ICT) evolves toward 6G, its deep integration with big data and artificial intelligence is shaping a new Information, Communication, and Big Data Technology (ICDT) integration paradigm. This integration-driven 6G system will extend beyond traditional communication networks, evolving into an intelligent information service system that integrates communication, sensing, and computing to enable seamless connectivity. Many 6G candidate technologies have already achieved significant progress in theoretical innovation, simulation verification, and prototype development. As a continuation of the 4.0 version, this white paper explores three core aspects of ICDT integration: the 6G technology framework, key technologies, and industry applications. The 6G technology framework establishes a systematic research roadmap, analyzing integration models, designing an ICDT-integrated 6G network architecture, and classifying candidate technologies and applications into interconnected categories. This approach helps identify key directions and potential breakthroughs for 6G development. The chapter on key technologies focuses on solutions rather than just challenges, as in version 4.0. It highlights advancements in massive MIMO, integrated sensing and communication, AI-driven communications, semantic communication, and quantum computing. Each domain is analyzed with the latest research, simulation data, and prototype testing results to outline solutions, implementation strategies, and achievements. The industry applications chapter delves into three representative use cases enabled by ICDT integration: immersive communication, the low-altitude economy, and passive IoT. It examines 4 / 87 these applications from the perspectives of key technologies, performance metrics, and industry needs, emphasizing how technological breakthroughs drive new applications and vice versa. The chapter presents a complete value chain from research to commercial deployment. ICDT-integrated 6G research is shifting from individual technology exploration to system architecture design, standardization, and industrial collaboration. This white paper advocates for deeper cross-disciplinary research, fostering a bidirectional mechanism linking technological innovation with application needs. It calls for cultivating an application-driven ecosystem, accelerating the adoption of new technologies across industries, and building an open, globally collaborative 6G technology landscape to drive innovation, standardization, and industrial synergy. 5 / 87 目 录 摘 要.......................................................................................................................................... 1 Abstract..................................................................................................................................... 3 引言............................................................................................................................................ 7 1 ICDT 融合的 6G 技术体系...................................................................................................8 1.1 通感算智融合的网络架构..............................................................................................8 1.2 ICDT 融合的 6G 技术簇.................................................................................................9 2 ICDT 融合的关键技术........................................................................................................11 2.1 超大规模 MIMO 技术...................................................................................................11 2.1.1 集中式超大规模 MIMO.........................................................................................11 2.1.2 分布式 MIMO 技术................................................................................................18 2.1.3 新型天线阵列与架构设计.....................................................................................27 2.1.4 近场技术.................................................................................................................29 2.2 通感互助........................................................................................................................38 2.2.1 通信赋能感知.........................................................................................................38 2.2.2 感知赋能通信.........................................................................................................39 2.3 通信与 AI 融合..............................................................................................................44 2.3.1 空口 AI....................................................................................................................44 2.3.2 智简网络.................................................................................................................48 2.4 语义通信........................................................................................................................58 2.4.1 基于对抗训练的无线语义通信安全传输.............................................................58 2.4.2 安全高效的分布式语义通信系统.........................................................................59 2.5 量子计算与应用............................................................................................................61 2.5.1 技术概念与应用.....................................................................................................61 2.5.2 技术挑战.................................................................................................................63 2.6 参考文献........................................................................................................................64 3 ICDT 融合的行业应用........................................................................................................66 6 / 87 3.1 沉浸式通信....................................................................................................................66 3.1.1 基本概念与场景用例.............................................................................................66 3.1.2 关键技术.................................................................................................................67 3.1.3 性能指标.................................................................................................................69 3.2 低空经济........................................................................................................................71 3.2.1 基本概念与场景用例.............................................................................................71 3.2.2 关键技术........................................................................
