Abstract: 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 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).

Abstract: A base station of the present invention configures resources in which a downlink signal is to be transmitted with zero power using resource sets defined for a specific number of antenna ports, regardless of the number of antenna ports actually configured in the base station, and transmits resource information indicating the configured resources to a user equipment. The user equipment of the present invention receives a downlink transmission from the base station, assuming that transmission power of resources corresponding to a resource set indicated by the resource information is zero.

Abstract: A method and apparatus for performing effective feedback in a wireless communication system supporting multiple antennas. A method for transmitting CSI of downlink transmission via uplink in a wireless communication system includes transmitting a joint-coded rank indicator (RI) and a first wideband (WB) precoding matrix indicator (PMI) at a first subframe, and transmitting a wideband channel quality indicator (WB CQI) and a second WB PMI at a second subframe. A user equipment (UE) preferred precoding matrix is indicated by a combination of the first PMI and the second PMI. If the RI is Rank-1 or Rank-2, the first PMI indicates one of subsets each having 8 indexes from among 16 indexes of the first PMI of a precoding codebook.
