Abstract: A method and apparatus are described for transmitting a channel state information (CSI) reporting at a user equipment (UE) in a wireless communication system. A rank indicator (RI) and a first type precoding matrix indicator (PMI) are transmitted to a base station (BS) according to a first CSI feedback type. A second type PMI and a channel quality information (CQI) are transmitted to the BS according to a second CSI feedback type. The RI and the first type PMI are jointly coded, and transmitted through a physical uplink control channel (PUCCH). A reporting period of the first type PMI is longer than a reporting period of the second type PMI. The first type PMI is a wideband PMI, and the second type PMI is a subband PMI. The reporting period of the first type PMI is equal to a reporting period of the RI.
