Method for receiving signal using interference removal scheme and apparatus for same in wireless communication system

A user equipment (UE) apparatus in a wireless communication system, the UE apparatus comprising:

• a Radio Frequency (RF) module;
• and
• a processor operably coupled with the RF module and configured to:
• receive, from a base station (BS), information of a set of subframes and information of a plurality of channel status information-reference signal (CSI-RS) configurations configured for the set of subframes,
• receive, from the BS, an indication indicating a first CSI-RS configuration among the plurality of CSI-RS configurations,
• estimate, on a first subframe included in the set of subframes, a first interference channel from a neighboring BS using resource elements corresponding to the first CSI-RS configuration, and
• receive, on the first subframe, a first downlink signal from the BS by applying reception beamforming to avoid the first interference channel,
• wherein the first downlink signal is not mapped to the resource elements corresponding to the first CSI-RS configuration,
• receive, on a second subframe which is not included in the set of subframes, a second downlink signal from the BS, and
• wherein the second downlink signal is received without estimating an interference channel from the neighboring BS.
