6G Terahertz Communications for Future Heterogeneous Wireless Network

随着电子设备和计算技术的快速发展，各种新兴应用（例如，大数据分析、人工智能和三维（3D）媒体、物联网等）带着大量的数据流量进入我们的社会。虽然移动的网络对于我们的社会“随时随地连接”已经是不可或缺的，但是未来移动的网络的一个主要特征（即，B5G：超越5G）的是非常巨大的数据量，这需要非常高的每设备吞吐量（多个Gbps，高达Tera bps：Tbps）和多个Tbps的每区域效率（Tbps/km 2）。尽管一些颠覆性的5G技术可能提供几Gbps的服务，但它仍然无法实现数百Gbps或Tbps的速率。在不久的将来，移动的通信网络的峰值速率预计将达到数百Gbps甚至Tbps速率，这需要非常高的频谱效率（例如，远高于10比特/秒/赫兹）在毫米波段或非常大的带宽（例如，超过20 GHz）。虽然前者非常具有挑战性，但后者可以在THz频段（大约100 GHz至10 THz）实现。在移动的和异构网络（HetNet）环境中设计具有非常高速率的普适接入是未来移动的网络发展的关键，因此，这个合作的6 G-TERAFIT的目标是在研究人员和工程师之间建立知识转移，他们将为未来B5 G超宽带的设计和实施做出贡献。快速的网络，并为他们成为科学，技术和工业领域的潜在领导者创造基础。该项目致力于打造一个多学科、跨行业的“卓越”教育培训平台。

With the fast development of electronic devices and computing technologies, various emerging applications (e.g., big data analysis, artificial intelligence and 3-dimensional (3D) media, Internet of things, etc.) have been entering our society with significant amounts of data traffic. While mobile networks are already indispensable to our society for "anywhere anytime connection," one main characteristic of future mobile networks (i.e., B5G: Beyond 5G) is the very huge amount of data, which requires very high throughput per devices (multiple Gbps, up to Tera bps: Tbps) and multiple Tbps per area efficiency (Tbps/km2). Though some disrupting 5G technologies may provide a few Gbps service, it is still not able to achieve hundreds of Gbps or Tbps rates. In the near future, the peak rate of mobile communication networks is expected to reach hundreds of Gbps or even Tbps rates, which requires either very high spectrum efficiency (e.g., much higher than 10 bits/s/Hz) in millimetre wave bands or very large bandwidth (e.g., more than 20GHz). While the former is very challenging, the latter can be achieved in THz bands (roughly, 100GHz to 10THz). The design of ubiquitous access with very high rates in mobile and heterogeneous network (HetNet) environments is the key to the development of future mobile networks, and so the objective of this collaborative 6G-TERAFIT is to create a knowledge transfer between the researchers and the engineers who will contribute to the design and implementation of future B5G ultra-fast networks and create the pedestal for them to become potential leaders in the resulting scientific, technological, and industrial fields. This project is committed to creating an "excellent" educational training platform that is multi-disciplinary and inter-sectoral in nature.
