1. A method for generating a channel state information (CSI) report of a terminal, comprising:

  • receiving at least two channel state information-reference signal (CSI-RS) resources from a serving cell of a base station based on a CSI-RS occasion which includes at least two subframes, wherein a first CSI-RS resource of the at least two CSI-RS resources is received in a first subframe of the CSI-RS occasion, a second CSI-RS resource of the at least two CSI-RS resources is received in a second subframe of the CSI-RS occasion, and each of the at least two subframes has a different subframe offset for the CSI-RS occasion, respectively;

    generating a CSI report corresponding to a CSI reference resource by assuming the first CSI-RS resource and the second CSI-RS resource as the CSI reference resource; and

    transmitting the CSI report to the base station,wherein the first CSI-RS resource corresponds to a non-zero power (NZP) CSI-RS resource and the second CSI-RS resource corresponds to a channel state information-interference measurement (CSI-IM) resource.
