A method of transmitting/receiving a discovery signal is provided. The method of transmitting the discovery signal is performed in a base station, the method comprising: determining M discovery signalresources from a discovery signal resource pool, where a part or all of the resources belonging to the discovery signal resource pool are determined to be the M discovery signal resources, where M isa natural number equal to or greater than 1; generating M discovery signal blocks, each of the M discovery signal blocks comprising a primary synchronization signal PSS, a secondary synchronization signal SSS, and a physical broadcast channel PBCH, and a reference signal for demodulating the PBCH; and transmitting an mth discovery signal block over an mth discovery signal resource of the M discovery signal resources, wherein m is a natural number from 1 to M.
