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.
