APPARATUS AND METHOD FOR ANALYZING PERFORMANCE ACCORDING TO INTER-CELL INTERFERENCE CONTROL BASED ON COORDINATED MULTIPOINT COMMUNICATION IN HETEROGENEOUS NETWORK

摘要

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.

1. An apparatus for analyzing performance according to inter-cell interference control based on coordinated multipoint communication in a heterogeneous network (HetNet), the apparatus comprising:
a communication unit configured to communicate with a user equipment (UE) and another device within the HetNet; and a control unit configured to calculate a priority of a cell center user (CCU) having a highest priority for each of three sectors of one cluster, compare the calculated priority of the CCU with a priority of a cell edge user (CEU) having a highest priority in the cluster, and control scheduling such that transmission to the CEU is performed using the CoMP transmission scheme if the priority of the CEU is higher than the priority of the CCU and transmission to the CEU is performed using a general transmission scheme if the priority of the CCU is higher than the priority of the CEU, wherein the control unit compares and analyzes performances caused by performing the scheduling when there are only macrocells or when there are picocells at the boundaries of the macrocells.
