Abstract: The present specification provides a method for performing measurements, by a terminal, in a coverage extension area of a small-scale cell in a wireless communication system in which macro cell and the small-scale cell coexist. The method for performing measurements can include the steps of: receiving information about a first subframe on which measurements for the small-scale cell can be performed and information about a second subframe on which measurements for the macro cell can be performed; when an interference cancellation function is set, measuring reference signal received power (RSRP) and a received signal strength indicator (RSSI) for the small-scale cell by driving the interference cancellation function on the first subframe; and measuring RSRP on the second subframe for the macro cell by driving the interference cancellation function and measuring the RSSI for the macro cell without driving the interference cancellation function.

Abstract: A method is provided for assisting measurement of a user equipment (UE). The method is performed by a serving cell for the UE. The serving cell determines whether a cell-specific reference signal (CRS) of the serving cell is to collide with a CRS of a second neighbor cell or whether a CRS of a first neighbor cell is not to collide with the CRS of the second neighbor cell, if the serving cell and the first neighbor cell correspond to aggressor cells to the second neighbor cell corresponding to a victim cell. The serving cell generates a second measurement subframe pattern based on an almost blank subframe (ABS) pattern in response to the determination, and transmits the second measurement subframe pattern for the first and second neighbor cells to the UE.
