The ever-increasing requirement on wireless data rates has been motivating technological innovations on wireless communications in both academia and industry. Among emerging research and development trends in wireless communications, Terahertz Band (0.1 – 10 THz) communication has been envisioned as one of the key enabling technologies in the next decade. With the ultra-wide available spectrum resources, THz band can provide terabits per second (Tbps) links for a plethora of applications. 

This talk will cover  the theoretical foundations of ultra-broadband communications in the THz band for mobile environments and bring the Tbps links one-step closer to reality. Our targeted breakthrough includes: 1) increasing the capacity of mobile wireless systems to reach Tbps, 2) overcoming the spectrum scarcity and capacity limitations of current mobile wireless networks, and 3) exploring the full potentials of THz spectrum for diverse communication scenarios. First, the concept of ultra-massive MIMO (UM MIMO) is introduced to overcome the transmission distance limitation, based on the use of the very large antenna arrays with thousands of antenna elements, especially for multi-hop THz links and THz mobile channels. The dynamic operation modes that include beamforming, spatial multiplexing and a combination of both, as well as the multi-band UM MIMO for THz mobile channels and multi-hop links will be analyzed. Second, accurate models for the end-to-end mobile THz channel will be developed with link-level performance analysis, which provide physical insights for THz communication system design in practical mobile communication scenarios. Third, by capturing the unique channel peculiarities, environment-aware adaptive resource allocation strategies will be investigated for THz mobile and multi-hop communications.
