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.

Abstract: A method of providing information for cell measurements. A first cell configures a subframe for performing a first measurement with respect to a first cell. A first position performing the first measurement is different from a second position performing a second measurement with respect to a second cell. The method includes transmitting, from the first cell to a user equipment (UE), first pattern information indicating the first position and second pattern information indicating the second position. A first subframe corresponding to the first pattern information is included in non-Almost Blank Subframe (ABS) subframes of the first cell, and a second subframe corresponding to the second pattern information is included in ABS subframes of the first cell. The ABS subframes of the first cell are configured as a first subframe at each of 8 subframes of the first cell.
