The present invention provides a method and a device for establishing a spatial channel model of fifth generation mobile communication, which can establish a channel model more accurately reflecting a wireless propagation environment of a fifth generation mobile communication system. The method for establishing the spatial channel model of the fifth generation mobile communication may comprise the following steps: establishing a wireless backhaul network propagation environment of an analysis target region considering a digital topographic map of the analysis target region and antenna information for the fifth generation mobile communication, and searching multiple propagation paths between a transmitting point and a receiving point in the wireless backhaul network propagation environment of the analysis target region based on a deterministic ray-tube (DRT) algorithm; collecting power delay distribution information of each of multiple propagation paths; and obtaining a spatial channel model parameter for the fifth generation mobile communication by clustering and merging the collected power delay distribution information through a K-means algorithm.;COPYRIGHT KIPO 2017
