ABSTRACT

Terahertz (THz) communications are envisioned as an up-and-coming and pivotal wireless technology for the sixth generation (6G) and beyond era. In particular, the ultra-wide THz band ranging from 0.1 to 10 THz offers enormous potential to alleviate the spectrum scarcity and break the capacity limitation of emerging wireless systems (such as 4G-LTE and 5G NR). This will undoubtedly support epoch-making wireless applications that demand ultra-high quality service requirements and multi-terabits per second data transmission in the intelligent information society in the 2030s, such as terabit-per-second backhaul systems, ultra-high-definition content streaming among mobile devices, and virtual/augmented reality. In this talk, I will introduce the role and importance of THz communications for the 6G and beyond wireless networks, while briefly describing the fundamental research on THz devices, channels, testbeds, and simulators. After this, I will give a brief summary of recent research advances in THz communications, focusing on performance analysis, spectrum allocation, and hybrid beamforming. Finally, I will discuss some pressing challenges for harnessing the benefits of THz communications in the next decades.
