Chinese Abstract:
With the promotion of 5g's global commercialization process, in order to meet the needs of higher rate, lower delay and new business in the future, 6G oriented research has been launched. Wireless channel is the channel of transmitting and receiving information. The characteristics of wireless channel determine the performance limit of wireless communication system. Therefore, the channel research is the basic research of 6G wireless communication system. This paper first introduces the possible technologies and applications of 6G, including terahertz communication, industrial Internet, space and space integrated network and machine learning, and points out that 6G channel model faces the challenges of higher frequency, wider bandwidth, super large-scale antenna array and further expansion of diversified scenes. Secondly, in view of these technologies and applications, this paper summarizes the current research progress of terahertz channel, industrial Internet channel, space and space channel measurement and modeling, as well as intelligent modeling based on machine learning and 3D environment reconstruction. Finally, facing the future, the paper looks forward to the problems that need further study in the above four aspects.
