Claim:
1. A method for detecting a small-scale cell in a wireless communication system in which a macro cell and the small-scale cell coexist, the method performed by a user equipment which is located outside a coverage of the small-scale cell and comprising: performing a measurement for the macro cell; comparing a value related to a reference signal received quality (RSRQ) obtained by the measurement for the macro cell with at least one threshold value; determining whether to operate at least one interference removing function in order to receive a signal from the small-scale cell, according to a result of comparing the value; and detecting the signal from the small-scale cell, if the interference removing function is operated, wherein the value related to the RSRQ is obtained by wherein the Iot is a density of a received power spectrum of total noise and interference for a resource element (RE) measured in an antenna connector, wherein the CRS_Es is a received energy for the RE in a valid part of symbols.
