Method and apparatus for CSI reporting in wireless communication system

A method performed by a base station in a communication system, the method comprising:

• transmitting, to a terminal, a plurality of channel state information (CSI) report configurations;
• and
• in case that two CSI reports are overlap in a time domain resource based on CSI report configurations, receiving, from the terminal, one of the two CSI reports having higher priority,
• wherein priority of a CSI report depends on at least one of a time domain transmission type of the CSI report and a report quantity type of the CSI report,
• wherein the time domain transmission type is prioritized over the report quantity type in an identification of the priority, and
• wherein the report quantity type is related to whether the CSI report includes a reference signal received power (RSRP) report.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to control to:
• receive, from a base station via the transceiver, a plurality of channel state information (CSI) report configurations,
• in case that two CSI reports overlap in a time domain resource based on the CSI report configurations, identify one of the two CSI reports having higher priority, and
• transmit, to the base station via the transceiver, the identified CSI report,
• wherein priority of a CSI report is identified based on at least one of a time domain transmission type of the CSI report and a report quantity type of the CSI report,
• wherein the time domain transmission type is prioritized over the report quantity type in an identification of the priority, and
• wherein the report quantity type is related to whether the CSI report includes a reference signal received power (RSRP) report.
