Summary:A method of selecting a path for transmitting a maximum power from a base station to a terminal includes simplifying a plurality of structures in an area by using OBBs, the area being an area in which beam search is to be performed; forming the plurality of simplified structures into a tree structure for ray tracing; performing the ray tracing by applying a ray tracing relation tree reduction (RRTR) algorithm for reducing an amount of computation of a GPU to the tree structure; and applying a linear regression (LR) algorithm for calculating the maximum power to be transmitted from the base station to the terminal based on a result of the ray tracing.
