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). 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, virtual/augmented reality, and wireless high-bandwidth secure communications.In this talk, I will describe the role and importance of THz communications for the 6G and beyond era, while briefly introducing 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, with focuses on performance analysis, spectrum allocation, and hybrid beamforming. Finally, I will discuss some significant challenges that future wireless system designers need to tackle for harnessing the benefits of THz communications in the 6G and beyond era.
