无线网络向第六代（6G）的演进正在推动对智能、灵活且节能的传播控制的需求。可重构全息表面（RHSs）通过密集排列的可编程单元实现精细的波前操控。本文引入了形状自适应RHSs，其动态改变表面几何形状以提供额外的空间自由度。该自适应设计响应环境动态变化，缓解阻塞，并提升城市通信、空中覆盖以及联合感知与通信场景中的性能。我们提出了一种网络架构，该架构在RHS处联合设计表面形状并优化传输。仿真结果表明，所提出的形状自适应RHSs显著提高了数据速率。这些发现确立了形状自适应RHS作为6G及未来无线网络中智能、上下文感知无线环境的基础技术。
英文摘要：
The evolution of wireless networks toward sixth-generation (6G) is driving demand for intelligent, flexible, and energy-efficient propagation control. Reconfigurable holographic surfaces (RHSs) enable fine-grained wavefront manipulation through densely packed programmable elements. This paper introduces shape-adaptive RHSs, which dynamically change surface geometry to provide extra spatial degrees of freedom. The adaptive design responds to environmental dynamics, mitigates blockages, and improves performance across urban communications, aerial coverage, and joint sensing and communication scenarios. We propose a network architecture that jointly designs the surface shape at the RHS and optimizes transmission. Simulation results show that the proposed shape-adaptive RHSs significantly increase data rates. These findings establish shape-adaptive RHS as a foundational technology for intelligent, context-aware wireless environments in 6G and beyond wireless networks.
