Method for reporting channel state information by terminal in wireless communication system and device for supporting same

A method of transmitting channel state information (CSI) by a user equipment (UE) in a wireless communication system, the method comprising:

• receiving, from a base station (BS), information on at least one CSI resource, wherein the information further comprises information on at least one analog beam;
• and,
• transmitting, to the BS, CSI feedback based on a certain number of CSI resource,
• wherein the at least one analog beam is related with the at least one CSI resource, respectively, and,
• wherein the certain number of the CSI resource is determined from among the at least one CSI resource based on maximum CSI calculation capability of the UE.

A user equipment (UE) for transmitting channel state information (CSI) in a wireless communication system, the UE comprising:

• a transmitter;
• a receiver;
• and
• at least one processor coupled with the transmitter and the receiver,
• wherein the at least one processor is configured to:
• receive, from a base station (BS), information on at least one CSI resource, wherein the information further comprises information on at least one analog beam;
• transmit, to the BS, CSI feedback based on a certain number of CSI resource,
• wherein the at least one analog beam is related with the at least one CSI resource, respectively, and,
• wherein the certain number of the CSI resource is determined from among the at least one CSI resource based on maximum CSI calculation capability of the UE.
