Abstract: A disclosure of the present specification provides a method for detecting a discovery signal. The method is a method for detecting discovery signals from a plurality of transmission points (TP) using the same physical cell identifier (PCID) and may comprise the steps of: determining scrambling identifiers of the discovery signals for the plurality of transmission points on the basis of the PCID which is commonly used by the plurality of transmission points and resource elements (REs) of the discovery signals transmitted from the plurality of transmission points; and demodulating the discovery signals on respective positions of the resource elements using the determined scrambling identifiers to detect the discovery signals.
