用于6 G通信中的NB-IoT服务的PDKEEPAAA星座中的波束成形

Beamforming in LEO Constellations for NB-IoT Services in 6G Communications

Alessandro Guidotti, Matteo Conti, Alessandro Vanelli-Coralli

摘要:

随着5G网络的首次商业化,超越5G(B5 G)或6 G,系统开始被定义。在这种情况下,物联网(IoT)服务将对5G系统产生更大的影响。为了应对大量的物联网设备,以及其中最先进的设备(例如,紧急情况下急救人员的实时摄像头信号),非地面系统将成为协助和补充地面网络的关键。在本文中,我们提出了一种基于地球同步轨道(GSO)和非地球同步轨道(NGSO)节点的多层非地面窄带物联网(NB-IoT)服务架构。为了应对设备的数量和潜在的大容量,我们建议在积极的全频率复用场景中实现最小均方误差(MMSE)波束成形。性能评估显示了所提出的解决方案的显著优势。

英文摘要:

With the first commercializations of 5G networks, Beyond 5G (B5G), or 6G, systems are starting to be defined. In this context, Internet of Things (IoT) services will be even more impactful with respect to 5G systems. In order to cope with the huge amount of IoT devices, and the potentially large capacity requirements for the most advanced of them (e.g., live camera feeds from first responders in emergency scenarios), non-terrestrial systems will be pivotal to assist and complement the terrestrial networks. In this paper, we propose a multi-layer non-terrestrial architecture for NarrowBand-IoT (NB-IoT) services based on Geosynchronous Orbit (GSO) and Non GSO (NGSO) nodes. To cope with both the number of devices and the potentially large capacities, we propose to implement Minimum Mean Square Error (MMSE) beamforming in an aggressive full frequency reuse scenario. The performance assessment shows the significant benefits of the proposed solution.
