摘要:

预计下一代5G网络将以高效、无缝和具有成本效益的方式提供每秒太比特数据速率通信服务和厘米级精度定位服务。然而,目前大多数通信和定位系统是分开设计的,导致无线电资源的利用率和网络性能下降。在本文中,我们提出了一个综合的通信和导航(ICAN)框架,以充分发挥超密集的LEO卫星网络的潜力,优化提供差异化服务。明确讨论了ICAN使能卫星系统的具体好处、可行性分析和挑战。特别地,设计了一种新颖的基于波束跳变的ICAN卫星系统解决方案,以自适应地调谐网络波束布局,用于双重功能的通信和定位目的。在此基础上,根据第三代合作伙伴计划(3GPP)定义的非地面网络仿真参数,搭建了完整的实验平台,验证了ICAN卫星系统的性能增益

英文摘要:

Next generation beyond 5G networks are expected to provide both Terabits per second data rate communication services and centimeter-level accuracy localization services in an efficient, seamless and cost-effective manner. However, most of the current communication and localization systems are separately designed, leading to an under-utilization of radio resources and network performance degradation. In this paper, we propose an integrated communication and navigation (ICAN) framework to fully unleash the potential of ultra-dense LEO satellite networks for optimal provisioning of differentiated services. The specific benefits, feasibility analysis and challenges for ICAN enabled satellite system are explicitly discussed. In particular, a novel beam hopping based ICAN satellite system solution is devised to adaptively tune the network beam layout for dual functional communication and positioning purposes. Furthermore, a thorough experimental platform is built following the Third Generation Partnership Project (3GPP) defined non-terrestrial network simulation parameters to validate the performance gain of the ICAN satellite system
