摘要: 针对灾害等引发地面蜂窝网络大面积中断场景,海量普通终端瞬时接入低轨卫星网络,面临卫星波束资源受限、同频干扰突出、地面频谱闲置等问题。针对6G星地协同NTN系统,研究应急场景跨域无线资源管理技术。构建地面断网后卫星业务接管的系统模型,提出分级优先级资源管理策略,联合优化功率、波束与时频资源;设计地面网络静默感知的频谱复用机制,在保护残余地面小区的前提下复用空闲授权频谱。仿真表明,该机制可提升应急关键业务吞吐量,为6G星地应急通信提供理论与方案支撑。

Abstract: Faced with large scale terrestrial cellular network outages induced by disasters, massive conventional user terminals will rapidly access low earth orbit satellite networks, resulting in limited satellite beam resources, severe co-channel interference, and low utilization of terrestrial licensed spectrum. Targeting 6G satellite-terrestrial cooperative non-terrestrial network (NTN) systems, this paper investigates cross domain radio resource management technologies for emergency communication scenarios. A system model of satellite service takeover under terrestrial network failure is constructed. On this basis, a hierarchical priority-based resource management strategy is proposed to jointly optimize power allocation, beam scheduling, and time-frequency resource configuration. Furthermore, a terrestrial network silence-aware dynamic spectrum reuse mechanism is developed, which enables the reuse of idle terrestrial licensed spectrum while guaranteeing the communication quality of residual terrestrial cells. Simulation results verify that the proposed scheme can significantly enhance the throughput of emergency critical services. This work provides effective theoretical support and technical solutions for 6G satellite-terrestrial emergency communications.

引言

星地协同非地面网络(NTN)以低轨卫星星座为核心,实现地面蜂窝网络与卫星网络深度融合,是6G全域覆盖、网络韧性增强的关键技术方向[1]。在标准化层面,3GPP从R17完成NTN基础框架定义[2],R18/R19完善再生载荷、星间链路、多普勒补偿、波束管理[3-4];R20面向6G重点研究应急动态频谱共享、星地无缝切换、灾害场景网络自愈机制[5],ITU‑R同步推进6G卫星接口、场景需求研究,为应急通信提供标准底座。

应急场景如地震、洪涝、台风等灾害会造成基站损毁、供电中断、传输链路断裂,形成局部区域地面网络失效,残余部分基站可维持小范围局部业务。传统应急手段(便携基站、高空平台)部署慢、覆盖范围有限,需要依靠卫星实现广域瞬时覆盖;但现有星地网络架构没有针对地面局部失效、存在残余小区这一典型灾害场景做专门优化。
