According to one embodiment of the present description, a method by which a terminal receives a search signal from a small-sized cell is provided. The method can comprise the steps of: receiving, from a serving cell, configuration set information of search signals of clustered neighboring small-sized cells for each cluster; determining configuration information of a search signal of each of the neighboring small-sized cells belonging to a corresponding cluster on the basis of the set information; and detecting a search signal from a corresponding small-sized cell on the basis of the determined configuration information.
