CELL SEARCH METHOD FOR SUPPORTING DISCONTINUOUS TRANSMISSION AND/OR RECEPTION OF BASE STATION

摘要

Disclosed is a cell search method for supporting discontinuous transmission and reception of small cell base stations. A cell search method performed by a base station, in an environment that a plurality of small cell base stations perform discontinuous transmission and reception, may comprise transmitting information about small cell base stations whose current transmission and reception mode is in active state; receiving, from a terminal, measurement results on the small cell base stations included in the information about small cell base stations; estimating small cell base stations located around the terminal based on the measurement results; and transmitting, to the estimated small cell to stations, an instruction to change their transmission and reception modes. Therefore, power consumption of the small cell base stations may be reduced with maintaining terminal performances for searching small cells.
