摘要:

期望下一代卫星通信(SatCom)网络支持极高的数据速率,以便无缝集成到未来的大型卫星-地面网络中。鉴于即将到来的频谱限制,主要的挑战是降低每比特的成本,这只能通过提高频谱效率来实现。此外,根据业务需求分布快速灵活地分配无线电资源的能力已经成为未来多波束宽带卫星系统的必要条件。本文介绍了无线电资源管理遇到的问题,在未来的宽带卫星通信的设计,并提供了一个全面的概述可用的技术来解决这些挑战。首先,我们专注于功率和带宽分配的需求匹配公式。其次,介绍了实际多波束卫星系统中的调度设计。最后,一些未来的挑战和各自的开放式研究课题进行了说明。

英文摘要:

Next-generation of satellite communication (SatCom) networks are expected to support extremely high data rates for a seamless integration into future large satellite-terrestrial networks. In view of the coming spectral limitations, the main challenge is to reduce the cost per bit, which can only be achieved by enhancing the spectral efficiency. In addition, the capability to quickly and flexibly assign radio resources according to the traffic demand distribution has become a must for future multibeam broadband satellite systems. This article presents the radio resource management problems encountered in the design of future broadband SatComs and provides a comprehensive overview of the available techniques to address such challenges. Firstly, we focus on the demand-matching formulation of the power and bandwidth assignment. Secondly, we present the scheduling design in practical multibeam satellite systems. Finally, a number of future challenges and the respective open research topics are described.
