AI总结:

针对卫星网络中通信与感知有效载荷独立演进的不可持续性问题,本文阐述6G卫星网络中联合通信与感知(JCAS)范式的作用,探讨其用例与挑战,以推动该技术成为下一代太空时代的基石。

摘要:

卫星网络(SN)长期以来提供两大基础服务:全球通信和面向地球的感知,支持从连接、导航到灾害管理和环境监测等应用。然而,数据需求的加速增长和新应用的出现使得通信与感知有效载荷的独立演进越来越不可持续。联合通信与感知(JCAS)已成为一种变革性范式,将两种功能集成在统一有效载荷中,以提高频谱效率、降低运营成本并减少硬件冗余。除效率外,这种集成还创造了单独有效载荷设计下无法实现的新型服务机会。本文阐述了JCAS在塑造第六代(6G)卫星网络中的作用,探讨了一个代表性用例以评估其可行性,并讨论了释放其全部潜力必须解决的关键挑战。通过强调空间环境固有的这些机会,我们旨在推动JCAS成为下一代太空时代的基石技术。

英文摘要:

Satellite networks (SN) have long provided two fundamental services: global communications and Earth-oriented sensing, supporting applications from connectivity and navigation to disaster management and environmental monitoring. Yet, the accelerating demand for data and the emergence of new applications render the independent evolution of communication and sensing payloads increasingly unsustainable. Joint communications and sensing (JCAS) has emerged as a transformative paradigm, integrating both functions within a unified payload to enhance spectral efficiency, reduce operational costs, and minimize hardware redundancy. Beyond efficiency, this integration creates opportunities for novel services that are infeasible under separate payload designs. This paper motivates the role of JCAS in shaping the sixth-generation (6G) of satellite networks, explores a representative use case to assess its feasibility, and discusses key challenges that must be addressed to unlock its full potential. By highlighting these opportunities inherent to the space environment, we aim to stimulate the development of JCAS as a cornerstone technology for the next-generation space era
