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（如大数据分析、人工智能和三维媒体、物联网等）已经进入我们的社会，带来了大量的数据流量。虽然移动网络已经成为我们社会不可或缺的“随时随地连接”，但未来移动网络（即B5G：超越5G）的一个主要特征是非常巨大的数据量，这需要非常高的每台设备吞吐量（多个Gbps，高达Tera bps: Tbps）和多个Tbps每区域效率（Tbps/km2）。尽管一些颠覆性的5G技术可能提供几Gbps的服务，但它仍然无法达到数百Gbps或Tbps的速率。在不久的将来，移动通信网络的峰值速率预计将达到数百Gbps甚至Tbps，这需要在毫米波频段具有非常高的频谱效率（例如远高于10比特/秒/赫兹）或非常大的带宽（例如超过20GHz）。虽然前者非常具有挑战性，但后者可以在太赫兹频段（大约100GHz到10THz）中实现。在移动和异构网络（HetNet）环境中以非常高的速率设计无处不在的访问是未来移动网络发展的关键，因此，这一合作6G-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B5G超高速网络的设计和实施做出贡献，并为他们创造基础，使他们成为由此产生的科学、技术、还有工业领域。本项目致力于打造一个多学科、跨部门的“优秀”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.
