1. A method performed by a terminal in a wireless communication system, the method comprising:
camping on a first cell on a first carrier frequency;
obtaining system information including configuration information while camping on the first cell, wherein the system information is broadcasted by a second cell;
identifying whether the obtained configuration information includes a discovery resource information for discovery message transmission on a second carrier frequency;
transmitting, to the first cell, a resource request message for discovery message transmission including information indicating a number of at least one discovery message for which the terminal requests and information indicating the second carrier frequency; and
in case that the obtained configuration information includes a discovery resource information for discovery message transmission on the second carrier frequency, transmitting a discovery message on the second carrier frequency based on the discovery resource information for discovery message transmission,
wherein in case that the obtained configuration information does not include a discovery resource information for discovery message transmission on the second carrier frequency, the discovery message on the second carrier frequency is not transmitted.
