Abstract  Abstract

FIELD: physics computer engineering.SUBSTANCE: invention relates to a wireless access system supporting multi-carrier aggregation (CA). The invention discloses a method for aperiodic feedback of channel state information (CSI) in a wireless access system supporting CA and according a version of the present invention comprises steps of: receiving a first message including an aperiodic CSI request field and uplink grant from a base station; receiving a second message including bitmap information indicating a downlink component carrier (DL CC) subjected to CSI measurement from the base station; measuring the CSI in consideration of at least one of the aperiodic CSI request uplink grant and bitmap information; and transmitting the measured CSI to the base station through a physical uplink shared channel (PUSCH).EFFECT: invention enables to decide the serving cell for which feedback is to be performed.14 cl 5 tbl 12 dwg
