    摘要: A method and apparatus for transmitting effective channel status information (CSI) in a wireless communication system supporting multiple carriers are disclosed. The method for indicating CSI transmission in a wireless communication system supporting multiple carriers includes transmitting downlink control information (DCI) including a channel quality information (CQI) request field to a user equipment (UE) over a physical downlink control channel (PDCCH), and receiving CSI reporting of a single downlink carrier or multiple downlink carriers from the UE over a physical uplink shared channel (PUSCH) without receiving uplink data. If the CSI for the single downlink carrier is reported, the number (NPRB) of resource blocks (RBs) established for the CSI reporting is identical to or less than X (NPRB≦X), and if the CSI for the multiple downlink carriers is reported, NPRB is identical to or less than M (where M>X).

    摘要: The present application relates to a method in which a terminal performs channel interleaving in a multi-antenna wireless communication system. More particularly, the method comprises the following steps: constructing both channel quality indicator (CQI) information and coded data information into preset bit-wide vectors to generate a first interleaver input vector sequence; repeating both rank indicator (RI) information and acknowledgement/negative acknowledgement (ACK/NACK) information per the number (NL) of transmission layers to generate a second interleaver input vector sequence of preset bit-wide vectors and a third interleaver input vector sequence of preset bit-wide vectors; mapping the first interleaver input vector sequence, the second interleaver input vector sequence, and the third interleaver input vector sequence to an interleaver matrix, respectively; and reading the interleaver matrix by a column basis to generate an output vector sequence. The preset bit-wide is defined by the product of a modulation order (Qpm) and the number (NL) of transmission layers.
