AI中文摘要:
通感一体化(ISAC)是第六代(6G)网络的基石,然而传统的固定天线系统缺乏应对动态用户和目标的灵活空间适应能力。新兴的夹捏天线(PA)通过沿波导动态重构辐射点,引入了大规模空间自由度,提供了一种灵活且低成本的解决方案。本文为PA赋能的ISAC建立了一个统一的架构视角。我们首先讨论了PA相较于现有灵活方案的独特优势,然后提出了一种PA赋能的ISAC框架,该框架同时支持上行和下行通信,并兼容无源和有源感知目标。在此框架内,我们识别了代表性应用场景,讨论了主要设计挑战,并强调了关键使能技术。一个数值案例研究展示了PA的可重构性如何影响通信-感知速率权衡。我们还概述了开放性问题,以指导未来6G网络中PA-ISAC的进一步研究。
英文摘要:
Integrated sensing and communication (ISAC) is a cornerstone of sixth-generation (6G) networks, yet conventional fixed-antenna systems lack the spatial adaptability to cope with dynamic users and targets. The emerging pinching antenna (PA) offers a flexible, low-cost solution by dynamically reconfiguring radiation points along waveguides, introducing large-scale spatial degrees of freedom. This article develops a unified architectural perspective for PA-enabled ISAC. We first discuss the unique advantages of PAs over existing flexible solutions, and then propose a PA-enabled ISAC framework that accommodates both uplink and downlink communication while being compatible with passive and active sensing targets. Within this framework, we identify representative application scenarios, discuss major design challenges, and highlight critical enabling techniques. A numerical case study demonstrates how PA reconfigurability affects the communication-sensing rate trade-off. We also outline open issues to guide further PA-ISAC research for future 6G networks.
