摘要

随着5G在全球范围内商业化进程的推进，为满足未来更高速率、更低延迟和新业务的需求，面向6G的研究已经启动。无线信道是收发两端信息传输的通道，无线信道的特性决定了无线通信系统的性能限。因此，关于信道的研究是6G无线通信系统研发的基础性研究。本文首先介绍了6G可能出现的技术和应用，包括太赫兹通信、工业互联网、空天地一体化网络和机器学习，并指出6G信道模型面临更高频率、更大带宽和超大规模天线阵列、多样化场景进一步扩展的挑战。其次，针对这些技术和应用，综述了目前太赫兹信道、工业互联网信道、空天地信道的测量与建模，以及基于机器学习和三维环境重构的智能化建模4个方面的研究进展。最后，面向未来，展望了上述4个方面有待深入研究的问题。

Abstract

With the commercialization of fifth generation networks worldwide

research into sixth generation (6G) networks has been launched to meet the demands for high data rates and low latency for future services. A wireless propagation channel is the transmission medium to transfer information between the transmitter and the receiver. Moreover

channel properties determine the ultimate performance limit of wireless communication systems. Thus

conducting channel research is a prerequisite to designing 6G wireless communication systems. In this paper

we first introduce several emerging technologies and applications for 6G

such as terahertz communication

industrial Internet of Things

space-air-ground integrated network

and machine learning

and point out the developing trends of 6G channel models. Then

we give a review of channel measurements and models for the technologies and applications. Finally

the outlook for 6G channel measurements and models is discussed.
