新兴场景，包括低空经济和智能交通，需要超可靠的通信和高精度的感知，这使得集成感知与通信（ISAC）成为第六代（6G）网络的关键使能技术。ISAC信号同时承载通信和感知功能，其设计直接影响ISAC系统的整体性能。本文提出了ISAC信号设计的渐进式路线图。首先，我们建立了一个涵盖通信、感知和射频（RF）性能的多维性能指标框架。其次，我们引入了一个三阶段的ISAC信号设计范式，即“释放潜力”、“扩展维度”和“深化协作”。该范式从利用现有信号出发，经过设计新的波形基和多维信号结构，发展到多节点协作的ISAC信号设计。最后，我们提出了相应的标准化路线图，该路线图从与现有通信系统的兼容性演进到原生及协作使能的ISAC。所提出的框架为ISAC信号设计和面向6G的标准演进提供了实用指导。
英文摘要
Emerging scenarios, including low-altitude economy and intelligent transportation, require ultra-reliable communi- cation and high-precision sensing, making integrated sensing and communication (ISAC) a key enabler for sixth-generation (6G) networks. The ISAC signal serves as the carrier for both communication and sensing, and its design directly affects the overall performance of ISAC system. This article presents a progressive roadmap of ISAC signal design. First, we establish a multi-dimensional performance metric framework of ISAC signal covering communication, sensing, and radio-frequency (RF) performance. Second, we introduce a three-stage ISAC signal design paradigm, namely UNLEASH POTENTIAL, EXPAND DIMENSIONS, and DEEPEN COLLABORATION. This paradigm progresses from the exploitation of existing signals, through the design of new waveform bases and multi-dimensional signal structures, to the ISAC signal design with multi-node cooperation. Finally, we propose a corresponding standardization roadmap that evolves from compatibility with existing communication sys- tems toward native and cooperation-enabled ISAC. The resulting framework provides practical guidance for ISAC signal design and the standard evolution toward 6G.
