Classification: CPC H  Y | IPC H

Claim 8:
9. A user equipment (UE) operating in a wireless communication system,
the UE comprising: at least one transceiver for transmitting and receiving a wireless signal; and at least one processor for controlling the at least one transceiver,
wherein the at least one processor configured to:
receive, 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;
receive a CSI-RS from the base station; and
transmit, to the base station, CSI derived using the CSI-RS, wherein the CSI-RS resource set is configured with a first CSI-RS 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.
