1. A user equipment (UE) to transmit at least one of a Channel Quality Indicator (CQI) and a Precoding Matrix Indicator (PMI), the UE comprising:
a processor to establish a Radio Resource Control (RRC) connection with a base station through a first serving cell, the first serving cell supporting a Time Division Duplex (TDD) mode; a receiver to receive an RRC message from the base station through the first serving cell; and a transmitter, wherein the processor is configured to determine the RRC message comprising carrier aggregation (CA) configuration information, the CA configuration information comprising information of a second serving cell supporting a Frequency Division Duplex (FDD) mode, and the first serving cell and the second serving cell being aggregated by a TDD-FDD CA scheme and determine a periodicity (Npd) and an offset (NOFFSET,CQI) based on a cqi-pmi-ConfigIndex received from the base station, the cqi-pmi-ConfigIndex being a numerical parameter, the periodicity (Npd) being a periodicity for periodically reporting at least one of CQI and PMI with respect to the second serving cell, the offset (NOFFSET,CQI) being an offset for periodically reporting the at least one of CQI and PMI, and the periodicity (Npd) being determined further based on a TDD UL(Uplink)/DL(Downlink) configuration of the first serving cell, and wherein the transmitter periodically transmits, to the base station, the at least one of CQI and PMI according to the periodicity (Npd) and the offset (NOFFSET,CQI) through the first serving cell or the second serving cell. |
