摘要

由于低轨卫星网络具有覆盖范围广、建设成本低的优势，利用低轨卫星对现有陆地移动通信网络进行覆盖补充并构建星地融合网络，是实现未来全球泛在连接通信愿景的可行方案。然而，由于低频段频谱资源有限且卫星波束干扰范围广，高效的星地频谱共享与干扰管理策略是星地融合网络的核心。为此，首先从星地融合网络中不同干扰场景入手，阐述了研究进展、挑战及现有方案的优势及劣势。随后，针对现有研究的不足之处，提出创新的干扰管理与频谱共享解决方案，并通过仿真验证所提方案的有效性。最后，对未来潜在的研究方向进行展望，以期对低复杂度的星地融合网络管理提供启发性思路。

Abstract

Due to the advantages in coverage and cost-effectiveness

low earth orbit satellites can provide supplemental coverage for terrestrial networks. Therefore

integrated satellite-terrestrial networks have emerged as a promising solution to achieve ubiquitous global connectivity. However

facing the challenges caused by the scarcity of spectrum resources and complex interference

effective interference management and spectrum sharing were the critical aspects of integrated satellite-terrestrial networks. Firstly

recent research progress and a comprehensive exploration of challenges for different interference scenarios were introduced. Then

to overcome the shortage of existing research

several potential and innovative technical solutions were presented

whose performance was verified by simulations. Finally

several potential future technical directions were discussed for integrated satellite-terrestrial networks.
