Abstract: One disclosure of the present specification provides an interference cancellation reception method. The interference cancellation reception method can comprise the steps of: cancelling an interference caused by a cell-specific reference signal (CRS) from a neighboring cell which is mixed within a signal received from a serving cell; blind-detecting a parameter related to a demodulation reference signal (DMRS) so as to discover whether the signal from the neighboring cell mixed within the received signal is a data channel modulated on the basis of the DMRS; cancelling an interference between the detected DMRS signal and a DMRS signal of the serving cell when the DMRS is detected on the basis of the DMRS-related parameter; blind-detecting a modulation order for the data channel from the neighboring cell; and receiving only the signal from the serving cell through the interference cancellation by the data channel from the neighboring cell on the basis of the modulation order.
