Abstract: A method of receiving a channel state information (CSI) report by a base station in a wireless communication system; the BS station (BS) therefore; a method of transmitting a CSI report by a user equipment (UE) in a wireless communication system; and the UE therefore are discussed. The method of receiving a CSI report according to one embodiment includes transmitting, via radio resource control (RRC) signaling, information for configuring at least one secondary cell (SCell) in addition to a primary cell (PCell) and a plurality of periodic CSI feedback configurations for a plurality of serving cells; and receiving, via a subframe of the PCell, a CSI report for only one of the plurality of serving cells.
