Method for transmitting control information and apparatus for same

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting uplink channel state information (CSI) in a wireless communication system that supports carrier aggregation, and to an apparatus for the method. The method for reporting CSI in a wireless communication system that supports carrier aggregation comprises the steps of: configuring a plurality of downlink component carriers (DL CCs); setting a CSI report mode on the plurality of DL CCs for each DL CC; and performing an operation for transmitting CSI according to the CSI report mode set on each DL CC. If a P-number of CSI overlap in the same subframe and a first condition is satisfied, a Q-number of CSI among the P-number of CSI are transmitted through a first physical channel, and if the P-number of SCI overlap in the same subframe and a second condition is satisfied, only an R-number of CSI among the P-number of CSI are transmitted through a second physical channel which is different from the first physical channel, wherein R is smaller than Q.

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.
