1. A method of transmitting channel state information, the method comprising: receiving, by a user equipment from a base station, both a radio resource control (RRC) signal and a physical downlink control channel (PDCCH), the RRC signal including a plurality of configurations for periodic channel state information (CSI) reports, the PDCCH including at least one control channel element (CCE), wherein a first CCE index indicating a first CCE of the at least one CCE identifies a physical uplink control channel (PUCCH); receiving, by the user equipment from the base station, a plurality of CSI reference signals (CSI-RSs); measuring, by the user equipment, each of the plurality of CSI-RSs to generate CSI; and transmitting, by the user equipment to the base station, the generated CSI based on the received RRC signal, wherein each of the plurality of configurations for the periodic CSI reports includes an indicator indicating an uplink subframe to be used for transmitting CSI corresponding to a specific one of the periodic CSI reports, and wherein the uplink subframe is indicated by the indicator in each of the plurality of configurations for the periodic CSI reports, not by the first CCE index identifying the PUCCH.
