摘要： 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. When CSI reports of two or more serving cells collide, CSI reports are dropped. When CSI reports of different serving cells having a same priority collide, CSI reports are dropped.
