1. A method for reporting, by a user equipment (UE), channel state information (CSI) in wireless communication system, the method comprising:
receiving configuration information related to a CSI report,
wherein the configuration information includes (i) first resource information for a channel measurement and (ii) second resource information for an interference measurement, and
wherein a first resource for the channel measurement is configured based on the first resource information and a second resource for the interference measurement is configured based on the second resource information;
receiving a reference signal based on the configuration information;
measuring a signal to interference noise ratio (SINR) based on the reference signal,
wherein the SINR is measured by applying Quasi co location (QCL) information configured to the first resource to the second resource; and
transmitting the CSI including the SINR,
wherein the second resource is a channel state information-interference measurement (CSI-IM) resource, and
wherein the QCL information corresponds to QCL type D.
