Abstract

The advent of the 6G era aims for ubiquitous connectivity, with the integration of non-terrestrial networks (NTN) offering extensive coverage and enhanced capacity. As manufacturing advances and user demands evolve, space-air-ground integrated networks (SAGIN) with computational capabilities emerge as a viable solution for services requiring low latency and high computational power. Resource management within joint communication and computing-embedded SAGIN (JCC-SAGIN) presents greater complexity than traditional terrestrial networks. This complexity arises from the spatiotemporal dynamics of network topology and service demand, the interdependency of large-scale resource variables, and intricate tradeoffs among various performance metrics. Thus, a thorough examination of resource management strategies in JCC-SAGIN is crucial, emphasizing the role of non-terrestrial platforms with processing capabilities in 6G. This paper begins by reviewing the architecture, enabling technologies, and applications in JCC-SAGIN. Then, we offer a detailed overview of resource management modeling and optimization methods, encompassing both traditional optimization approaches and learning-based intelligent decision-making frameworks. Finally, we outline the prospective research directions in JCC-SAGIN.

联合通信与计算嵌入式 SAGIN 中的资源管理概览

6G时代的到来旨在实现无处不在的连接，非地面网络（NTN）的整合提供了广泛的覆盖范围和增强的容量。随着制造业的进步和用户需求的发展，具有计算能力的空-空-地集成网络（SAGIN）成为需要低延迟和高计算能力的服务的可行解决方案。联合通信和计算嵌入式SAGIN （JCC-SAGIN）中的资源管理比传统地面网络更复杂。这种复杂性源于网络拓扑和服务需求的时空动态、大规模资源变量的相互依赖以及各种性能指标之间的复杂权衡。因此，对JCC-SAGIN中的资源管理策略进行彻底检查至关重要，强调具有6G处理能力的非地面平台的作用。本文首先回顾JCC-SAGIN中的体系结构、启用技术和应用程序。然后，我们详细概述了资源管理建模和优化方法，包括传统的优化方法和基于学习的智能决策框架。最后，对JCC-SAGIN的未来研究方向进行了展望。

期刊介绍： IEEE Communications Surveys & Tutorials is an online journal published by the IEEE Communications Society for tutorials and surveys covering all aspects of the communications field. Telecommunications technology is progressing at a rapid pace, and the IEEE Communications Society is committed to providing researchers and other professionals the information and tools to stay abreast. IEEE Communications Surveys and Tutorials focuses on integrating and adding understanding to the existing literature on communications, putting results in context. Whether searching for in-depth information about a familiar area or an introduction into a new area, IEEE Communications Surveys & Tutorials aims to be the premier source of peer-reviewed, comprehensive tutorials and surveys, and pointers to further sources. IEEE Communications Surveys & Tutorials publishes only articles exclusively written for IEEE Communications Surveys & Tutorials and go through a rigorous review process before their publication in the quarterly issues. A tutorial article in the IEEE Communications Surveys & Tutorials should be designed to help the reader to become familiar with and learn something specific about a chosen topic. In contrast, the term survey, as applied here, is defined to mean a survey of the literature. A survey article in IEEE Communications Surveys & Tutorials should provide a comprehensive review of developments in a selected area, covering its development from its inception to its current state and beyond, and illustrating its development through liberal citations from the literature. Both tutorials and surveys should be tutorial in nature and should be written in a style comprehensible to readers outside the specialty of the article.
