Abstract:
1. A method for reporting channel state information (CSI) in a wireless communication system that supports carrier aggregation, the method comprising: configuring a plurality of downlink component carriers (DL CCs); setting a CSI report mode corresponding to the plurality of DL CCs for each DL CC; and performing an operation for transmitting CSI in accordance with the CSI report mode set corresponding to each DL CC, wherein, if a P-number of CSIs overlap with one another for the same subframe and a first condition is satisfied, a Q-number of CSIs among the P-number of CSIs are transmitted through a first physical channel, and if the P-number of CSIs overlap with one another for the same subframe and a second condition is satisfied, only an R-number of CSIs among the P-number of CSI are transmitted through a second physical channel which is different from the first physical channel, R being smaller than Q.
