Abstract
The present invention relates to a method and an apparatus for establishing a cell using system information of neighboring cells on the basis of interference environments of the neighboring cells in a wireless communication system. The method according to the present invention comprises the steps of: detecting, by a base station, cell IDs of neighboring cells by using synchronization signals transmitted from the neighboring cells; checking whether resources, to which common reference signals (CRS) transmitted from the neighboring cells are transmitted, overlap with each other, on the basis of the cell IDs; estimating channels of the neighboring cells by using the CRSs; and determining an interference environment for establishing a cell by using the result of the checking and the estimated channels.
