Abstract: A method for transmitting channel status information in a wireless communication system. A user equipment (UE) transmits first channel information indicating a set of precoding matrices to a base station (BS) periodically, and transmits second channel information indicating one precoding matrix included in the set of precoding matrices to the BS periodically.

Abstract: A method for transmitting uplink control information by a communication apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless communication system. Only one Physical Downlink Shared Channel (PDSCH) is received on the PCell among the plurality of cells in a first subframe. Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information about the PDSCH is transmitted through a Physical Uplink Control Channel (PUCCH) in a second subframe configured for Scheduling Request (SR) transmission. For a positive SR in the second subframe, the HARQ-ACK information is transmitted using a SR PUCCH resource. For a negative SR in the second subframe, the HARQ-ACK information is transmitted using a HARQ-ACK PUCCH resource different from the SR PUCCH resource.
