Provided is a method of analyzing performance according to inter-cell interference control based on coordinated multipoint (CoMP) communication in a heterogeneous network (HetNet) to check that performance is enhanced by applying a variety of scheduling and pre-coding based on the CoMP communication in a HetNet environment of a Long Term Evolution-Advanced system to analyze the performance. The method applies a variety of scheduling and pre-coding based on coordinated beamforming scheme of CoMP communication technology, where the scheduling includes coordinated scheduling technique and the precoding includes QR decomposition, Tomlinson-Harashima precoding, polar decomposition, and singular value decomposition techniques, and compares and analyzes performances when there are only macrocells or when there are picocells at the boundaries of the macrocells, thereby checking that the gain is enhanced.
