Mobile Teraherz Communication will enable future business visions such as internet of vehicles, high-capacity wireless backhaul, and holographic communication. In order to cope with the challenge of link transmission caused by mobility and path loss, it is necessary to develop terahertz large-scale antenna array communication. However, narrow-beam alignment and tracking of large-scale array antennas restrict mobility. The demand, present situation and technical bottleneck of mobile terahertz communication are summarized. Firstly, the basic theory of bottleneck is summarized, including performance index modeling, performance equilibrium modeling, and perceptual cooperation scheme under time-division and frequency division system. After that, the technology of perceptive cooperative terahertz mobile communication is summarized, including beamforming, channel estimation, channel tracking, simulation platform of perceptive cooperative communication for system design. Finally, the application test of sensing cooperative mobile terahertz communication is introduced, and the terahertz communication system ranging, terahertz large-scale liquid crystal phased array communication and sensing cooperative large-scale liquid crystal phased array mobile communication are respectively realized, and the performance gain of the proposed technology is verified.
