One disclosure of the present invention provides a discovery signal receiving method. The method may comprise the steps of: identifying, through a physical control format indicator channel (PCFICH) received from a small-scale cell over a first orthogonal frequency division multiplexing (OFDM) symbol of a downlink sub-frame, the position of an OFDM symbol over which a downlink control channel is received; and determining a resource region on which a discovery signal is received from the small-scale cell. In the determining step, it can be assumed that the resource region on which the discovery signal is received does not overlap a resource region on the OFDM symbol over which the downlink control channel is received.
