Claim:
1. A method for reporting a channel state in a wireless communication system, the method being performed by a terminal and comprising: reporting channel state information (CSI) to a base station (BS); receiving at least one transport block from the BS; transmitting acknowledgement/negative acknowledgement (ACK/NACK) feedback information for the at least one transport block to the BS, a resource for transmitting the ACK/NACK feedback information being determined based on CSI correction information for correcting the reported CSI; and receiving a downlink channel scheduled based on the CSI correction information, wherein the CSI correction information indicates a change in channel state due to dynamic interference, wherein a plurality of PUCCH (Physical Uplink Control Channel) resources are configured for the terminal, wherein a value of the CSI correction information is mapped to the plurality of PUCCH resources, and wherein the value of the CSI correction information is indicated to the BS by the resource used for transmitting the ACK/NACK feedback information determined from the plurality of PUCCH resources.
