Abstract | 论坛简介

Reconfigurable Intelligent Surfaces (RIS) enable programmable manipulation of the wireless propagation environment through controllable reflection, refraction, and scattering mechanisms. As a pivotal enabling technology for sixth-generation (6G) systems, RIS are expected to deliver coverage enhancement, energy-efficient connectivity, blockage mitigation, and cost-effective network densification across sub-6 GHz, millimeter-wave (mmWave), and terahertz (THz) frequency bands. Beyond these system-level benefits, RIS further provide a versatile platform for wideband channel shaping and near-field beam focusing, low-overhead channel state information (CSI) acquisition and beam training, and joint active–passive beamforming design. Moreover, RIS-assisted architectures can support integrated sensing and communications (ISAC), high-precision localization, and enhanced physical-layer security, including covert communications. Our objective is to advance RIS from a promising physical-layer concept to a deployable, 6G-grade technology by addressing the fundamental tradeoffs among reconfigurability, channel acquisition overhead, hardware constraints, and end-to-end performance in wideband and near-field regimes.

可重构智能表面（RIS）通过对反射、折射和散射机制进行可编程控制，实现对无线传播环境的可编程调控。作为第六代（6G）移动通信系统的关键使能技术，RIS 有望在 sub-6 GHz、毫米波（mmWave）以及太赫兹（THz）等频段实现覆盖增强、能效提升、遮挡缓解以及低成本网络致密化。除系统层面的优势外，RIS 还为宽带信道塑形与近场波束聚焦、低开销信道状态信息（CSI）获取与波束训练、以及有源–无源联合波束成形设计提供了灵活平台。此外，RIS 赋能的体系架构可支持感知通信一体化（ISAC）、高精度定位以及增强型物理层安全（包括隐蔽通信）。本专题旨在推动 RIS 从具有潜力的物理层概念走向可部署的 6G 级关键技术，重点解决在宽带与近场场景下可重构能力、信道获取开销、硬件约束与端到端性能之间的核心权衡问题。
