Claim:
1. A method for performing a measurement at a user equipment (UE) in a mobile communication system, the method comprising: receiving, at the UE from a primary cell, measurement configuration information of a discovery signal of a secondary cell in an off-state; and based on the measurement configuration information, measuring, at the UE, a Reference Signal Received Power (RSRP) or a Received Signal Strength Indicator (RSSI) of the discovery signal, wherein the measurement configuration information indicates a frequency of the discovery signal, a periodicity of the discovery signal, and a subframe offset of the discovery signal, wherein the measurement configuration information further indicates that the UE should not assume to receive a cell reference signal (CRS) within a subframe except for a subframe configured to receive the discovery signal, and wherein the measurement configuration information is received via a radio resource control (RRC) message.
