Abstract

The radio communication division of the International Telecommunication Union (ITU-R) has recently adopted integrated sensing and communication (ISAC) among the key usage scenarios for IMT-2030/6G. ISAC is envisioned to play a vital role in the upcoming wireless generation standards. In this work, we bring together several paramount and innovative aspects of ISAC technology from a global 6G standardization perspective, including both industrial and academic progress. Specifically, this article provides 6G requirements and ISAC-enabled vision, including various aspects of 6G standardization, benefits of ISAC co-existence, and integration challenges. Moreover, we present key enabling technologies, including intelligent metasurface-aided ISAC, as well as orthogonal time frequency space (OTFS) waveform design and interference management for ISAC. Finally, future aspects are discussed to open various research opportunities and challenges on the ISAC technology toward 6G wireless communications.

面向 6G 的综合传感与通信：关键使能技术、标准化和挑战

国际电信联盟（ITU-R）无线电通信部门最近将综合传感与通信（ISAC）纳入 IMT-2030/6G 的主要使用场景。根据设想，ISAC 将在即将到来的无线一代标准中发挥重要作用。在这项工作中，我们从全球 6G 标准化的角度，汇集了 ISAC 技术的几个重要和创新方面，包括工业和学术进展。具体来说，本文提供了 6G 要求和 ISAC 支持的愿景，包括 6G 标准化的各个方面、ISAC 共存的优势和集成挑战。此外，我们还介绍了关键的使能技术，包括智能元表面辅助 ISAC，以及用于 ISAC 的正交时频空间（OTFS）波形设计和干扰管理。最后，我们讨论了未来的发展方向，为 ISAC 技术迈向 6G 无线通信提供了各种研究机会和挑战。
