Classification: CPC H | IPC H

Claim 8:
9. An operation method of a terminal in a communication system, the operation method comprising:
receiving first indication information from a base station, the first indication information indicating use of a first channel quality information (CQI) table among CQI tables;
receiving a first reference signal from the base station;
selecting a first CQI index within the first CQI table based on the first reference signal; and
transmitting first channel state information (CSI) to the base station, the first CSI including the first CQI index,
wherein the CQI tables include the first CQI table and a second CQI table, and a spectral efficiency indicated by at least one CQI index within the first CQI table is identical to a spectral efficiency indicated by at least one CQI index within the second CQI table, and
wherein the first indication information further includes triggering information indicating a scheme of changing a CQI table used for CSI reporting.
