One disclosure of the present specification provides a method for receiving interference cancellation. The method for receiving interference cancellation can comprise: a step for cancelling, in signals received from a serving cell, cell-specific reference signals (CRS) from the serving cell, the CRS from a first primary interference cell, and the CRS from a second primary interference cell; a step for comparing the signal size of the serving cell, the signal size of the first primary interference cell, and the signal size of the second primary interference cell; a step for determining whether the CRS of the serving cell conflicts with the CRS of the first primary interference cell or the CRS of the second primary interference cell; and a step for canceling, when it is determined that the CRS' conflict with one other, data signals from the first primary interference cell and data signals from the second primary interference cell in the signals where the CRS are cancelled in the order determined according to the size comparison of signals.
