摘要： 6G将向更高频段扩展，并高效利用低中高全频谱资源。其中，低频段频谱仍将是6G发展的战略性资源，毫米波将在6G时代发挥更重要作用，而太赫兹等更高频段将重点满足特定场景的短距离大容量需求。当前针对太赫兹的传播模型处于空白阶段，从6G应用愿景出发，结合太赫兹频段特点，对太赫兹频段的传播模型进行了探讨。

Review of research on 6G Terahertz propagation model

Abstract： 6G would expand to higher frequency bands and make efficient use of low, medium and high full spectrum resources. The low-frequency spectrum will still be a key strategic resource for the development of 6G. Compared with present, Millimeter wave will play a more important role in the 6G era. Terahertz and other higher frequency bands will focus on meeting the short-range and high-capacity needs of specific scenes. At present, the propagation model for Terahertz is in the blank stage. Starting from the vision of 6G service and combined with the characteristics of Terahertz frequency band, this paper will discuss and review the research of communication propagation model in Terahertz frequency band.
