Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a non-periodical channel state information feedback method suitable in a wireless connection system for supporting multi-carrier aggregation.

SOLUTION: A method for allowing a terminal to non-periodically feed back CSI(Channel State Information) in a wireless connection system for supporting a CA(Carrier Aggregation) system includes: receiving a first message including a non-periodical CSI request field and an uplink grant from a base station; receiving a second message including bit map information indicating a DL CC(Downlink Component Carrier) as the measurement target of the CSI; measuring the CSI under the consideration of one or more of the non-periodical CSI request field the uplink grant and the bit map information; and transmitting the measured CIS via PUSCH(Physical Uplink Shared Channel) to the base station for non-periodical feedback.
