Abstract: The present invention relates to a wireless access system supporting an unlicensed band and provides a method for reporting channel state information (CSI) on a transmission opportunity (TxOP) duration, and devices supporting the same. According to one embodiment of the present invention, a method by which a user equipment (UE) reports CSI of a TxOP duration in a wireless access system supporting carrier aggregation (CA) with the unlicensed band comprises the steps of: receiving CSI interference measurement (CSI-IM) configuration information related to the TxOP duration through a primary cell (Pcell); measuring an interference amount in subframes of a secondary cell (Scell), in which CSI-IM is set, on the basis of the CSI-IM configuration information; measuring CSI of the TxOP duration for the Scell by using the interference amount; and transmitting the CSI to a base station, wherein the Pcell can be a serving cell configured in a licensed band, and the Scell can be a serving cell configured in the unlicensed band.
