SYSTEM AND METHOD FOR INTERFERECNE CANCELLATION IN MULTICELL MULTIUSER ENVIRONMENT

摘要

PURPOSE: A system and a method for interference cancellation in multi cell multiuser environment are provided to solve the interference problem of an intra cell and an extra cell through the process of self-configuration and self-optimization of a SON(Self-Organizing Network). CONSTITUTION: A base station(200) forms the neighboring base station with a network through setting about a set parameter which satisfies a first conditional expression which is set in each cell area located in each user terminal(100). The base station exchanges channel information. The base station calculates a set parameter which satisfies a preset second conditional expression for reducing the interference about each user terminal and a plurality of cell area on the network based on the channel information. The base station feeds back the calculated parameter to the user terminal.
