        Abstract: Currently, it is urgent to carry out the investigations of new radio propagation characteristics in the 5th generation (5G)mobile communication scenarios as well as their impacts on the key enabling technologies for 5G systems.From this perspective, we first perform a comprehensive literature survey and then identify the main requirements, current status and challenges of the wireless channel modeling strategies in the context of high frequency communications, massive multiple-input multiple-output (MIMO) as well as device-to-device communications in this manuscript.In addition, we also point out five open issues in this area that need further studies.The potential research findings can lay a solid foundation for the optimized design and accurate evaluation of related algorithms in 5G scenarios such as continuous wide-area coverage, high-capacity hot spots, great connection with low-power consumption, and low latency and high reliability.
