Method for measuring and reporting channel state information in wireless communication system and device therefor

A user equipment configured to perform channel state information (CSI) reporting in a wireless communication system, the user equipment comprising:

• a transceiver;
• at least one processor;
• and
• at least one computer memory operatively connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations that comprise:
• receiving, from a base station, CSI configuration information related to the CSI reporting, wherein each of a plurality of reporting settings included in the CSI configuration information is configured in association with one or more resource sets;
• receiving, from the base station, information representing i) a specific reporting setting among the plurality of reporting settings and ii) a specific resource set associated with the specific reporting setting;
• and
• performing the CSI reporting based on the specific reporting setting and the specific resource set,
• wherein each index of at least one resource set related with the specific reporting setting is re-numbered based on the specific reporting setting.

A processing device configured to control a user equipment to perform channel state information (CSI) reporting in a wireless communication system, the processing device comprising:

• at least one processor;
• and
• at least one computer memory operatively connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations that comprise:
• receiving, from a base station, CSI configuration information related to the CSI reporting, wherein each of a plurality of reporting settings included in the CSI configuration information is configured in association with one or more resource sets;
• receiving, from the base station, information representing i) a specific reporting setting among the plurality of reporting settings and ii) a specific resource set associated with the specific reporting setting;
• and
• performing the CSI reporting based on the specific reporting setting and the specific resource set,
• wherein each index of at least one resource set related with the specific reporting setting is re-numbered based on the specific reporting setting.
