摘　　要：卫星通信是超五代与第六代通信网络的重要组成部分。随着陆海空天一体化信息网络和卫星互联网的发展,高通量卫星(High Throughput Satellite,HTS)能够较好地满足当前呈爆炸式增长的业务需求。介绍了HTS无线资源管理的两大技术路线和基本问题。分别针对带宽和功率分配、无线电资源调度综述了资源管理方法近十年的研究进展,介绍了常用系统模型和优化算法,重点聚焦了波束布局设计中与波束宽度、位置、波束-用户映射相关的多维自由度优化问题及技术。面向非对地静止网络提出了HTS无线资源管理面临的挑战。Satellite communication is a significant part of beyond 5G(B5G)and 6G communication networks.With the development of the integrated land-sea-air-space information networks and satellite internet,high throughput satellite(HTS)can better meet the explosive growth of service demands.The two major technical routes and difficulties of HTS radio resource management are introduced.The research progress of resource management methods for bandwidth and power allocation,radio resource scheduling,and overview of the past ten years are separately introduced,including commonly used system models and optimization algorithms.The focus is on the multi-degree-of-freedom optimization problem and technologies related to beam layout design,including beam width,beam position,and beam-user mapping.The challenges faced by HTS radio resource management in non-geostationary orbit networks are presented.
