1. A method of receiving a signal, which is received by a user equipment in a wireless communication system, the method comprising:
- receiving a plurality of subframes including a first subframe and a second subframe; and
performing a channel estimation using either a cell specific reference signal (CRS) or a channel state information-reference signal (CSI-RS) in accordance with information related to a time-frequency resource having the first subframe and the second subframe correspond thereto,wherein a first interference is measured in the first subframe for performing the channel estimation using the CRS, and a second interference is measured in the second subframe for performing the channel estimation using the CSI-RS,wherein when the user equipment measures interferences in the plurality of subframes, both of the first interference and the second interference are considered together if the user equipment receives a prescribed information, andwherein the prescribed information indicates whether a transmission power of a whole serving transmitting point of the user equipment is zero in a zero power CSI-RS, when the second interference is measured using the zero power CSI-RS.

10. In a wireless communication system, a user equipment device comprising:
-
a receiving module; and a processor, wherein the processor is configured to; control the receiving module to receive a plurality of subframes including a first subframe and a second subframe, and perform a channel estimation using either a cell specific reference signal (CRS) or a channel state information-reference signal (CSI-RS) in accordance with an information related to a time-frequency resource having the first subframe and the second subframe correspond thereto, wherein a first interference is measured in the first subframe for performing the channel estimation using the CRS, and a second interference is measured in the second subframe for performing the channel estimation using the CSI-RS, wherein when the user equipment measures interferences in the plurality of subframes, both of the first interference and the second interference are considered together if the user equipment receives a prescribed information, and wherein the prescribed information indicates whether a transmission power of a whole serving transmitting point of the user equipment is zero in a zero power CSI-RS, when the second interference is measured using the zero power CSI-RS.
