Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The method is for phase correction of an antenna in a large-capacity antenna system, the method includes grouping large-capacity antennas into a predetermined number of groups; setting a path such that ports of the grouped antennas have a feedback path; outputting a test signal to be outputted to each antenna port of each group by adding a code or sequence having orthogonality; separating signals for each antenna port in the group by using the code or sequence having orthogonality in a signal received through the feedback path; and calculating a calibration value by detecting a phase change of the separated signal.

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.
