Claim 0:
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, configuration information related to channel state information (CSI) resource setting,
wherein the configuration information includes information on a CSI-reference signal (CSI-RS) resource set;
receiving a CSI-RS from the base station; and
transmitting, to the base station, CSI derived using the CSI-RS,
wherein the CSI-RS resource set is configured with a first resource group, a second resource group and N (N is a natural number) resource pairs,
wherein the CSI includes i) one CSI-RS resource indicator (CRI) corresponding to one resource pair of the N resource pairs and ii) two precoding matrix indicators (PMIs) associated to a first resource of the first resource group and a second resource of the second resource group, respectively, of the one resource pair of the N resource pairs,
wherein the two PMIs for the one resource pair are derived based on the one CRI for the one resource pair, and
wherein, for deriving a PMI for the first resource group, interference from the second resource of the one resource pair is derived.
