Method for reporting channel state information in wireless communication system and apparatus for same

A user equipment (UE) configured to perform a beam-related reporting in a wireless communication system, the UE comprising:

• a radio frequency (RF) transceiver;
• and
• a processor controlling the RF transceiver,
• wherein the processor is configured to:
• receive, from a base station via the RF transceiver, resource setting information;
• wherein the resource setting information includes a plurality of resource configurations for a plurality of channel state information-reference signal (CSI-RS) resources, with each resource configuration corresponding to each CSI-RS resource,
• wherein the plurality of CSI-RS resources comprise (i) a non-zero power CSI-RS resource, (ii) a zero power CSI-RS resource, and (iii) a non-zero power CSI-RS resource for interference,
• wherein based on the plurality of CSI-RS resources being configured for a beam management, each of the plurality of resource configurations includes indication information for a subcarrier location of each CSI-RS resource, and
• wherein a resource configuration corresponding to the non-zero power CSI-RS resource for interference includes an indicator indicating that the non-zero power CSI-RS resource for interference is related to interference cancellation;
• and
• receive, from a base station via the RF transceiver, the plurality of CSI-RS resources based on the resource setting information,
• wherein the plurality of CSI-RS resources are repeatedly received via different reception (RX) beam candidates of the UE;
• and
• transmit, to the base station via the RF transceiver, a beam-related report generated based on the plurality of CSI-RS resources.
