1. A method for reporting channel state information (CSI) to which interference cancellation capability is reflected in a wireless communication system, the method being performed by a terminal and comprising:
receiving one or more CSI process configurations comprising one or more CSI resource sets from a serving cell, the CSI resource set being associated with a specific interference cell;
detecting a dominant interference signal from a received signal;
selecting a CSI resource set corresponding to the dominant interference signal;
calculating the CSI to which interference cancellation capability is reflected, using interference hypothesis (IH) information corresponding to the selected CSI resource set; and
reporting the calculated CSI to the serving cell through a CSI process corresponding to the IH information corresponding to the selected CSI resource set,
wherein the CSI resource set comprises:
CSI-reference signal (RS) configuration information of the serving cell,
cell-specific RS (CRS) or CSI-RS configuration information of the specific interference cell, and
CSI-interference measurement (IM) resource information, and
wherein the IH information comprises information about a transmission scheme of interference signal, and
wherein the IH information is provided for each interference cell, and comprises N or fewer IH elements corresponding to the one or more CSI resource sets for L timings, where N is a maximum number of CSI processes configured for the terminal.
