Abstract: The present invention provides various methods for transmitting channel state information relative to one or more serving cells in a carrier-coupled environment, and devices for supporting the same. As one embodiment of the present invention, a method for reporting channel state information (CSI) in a wireless access system that supports carrier coupling comprises the steps of: allowing a terminal to receive information related to a CSI report mode for one or more serving cells from a base station; and allowing the terminal to report the channel state information (CSI) on the one or more serving cells to the base station by considering the CSI report mode. In this case, if first type CSI for a first serving cell and second type CSI for a second serving cell are transmitted on the same subframe, the terminal can report CSI for one serving cell only, to the base station, according to priorities of CSI report types related to the CSI report mode.

Abstract: 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.
