Track 4

Track 4. Millimeter-Wave and Terahertz Communication

Chair: Yaxin Zhang, University of Electronic Science and Technology of China, China
Co-Chair: Hao Gao, Southeast University, China
Co-Chair: Chao Tang, Tohoku University, Japan
Co-Chair: Weijie Gao, The University of Osaka, Japan

This track focuses on millimeter-wave and terahertz communication technologies as key enablers for next-generation wireless systems. It addresses fundamental theories, channel modeling, device and circuit design, as well as advanced transmission and networking techniques operating in high-frequency bands. By exploiting the abundant spectrum resources of millimeter-wave and terahertz frequencies, these technologies promise ultra-high data rates, low latency, and massive connectivity. The track also explores challenges such as severe path loss, hardware constraints, beam management, and atmospheric absorption, along with emerging solutions including intelligent beamforming, reconfigurable intelligent surfaces, and integrated sensing and communication. Contributions are welcomed on both theoretical advances and practical implementations supporting future 6G networks and beyond.
