Abstract
The present invention relates to a wireless communication system, and more particularly, discloses a method and a device for transmitting/receiving channel state information in a wireless communication system supporting multicarriers. The method for transmitting downlink channel state information in the wireless communication system supporting downlink multicarriers, according to one embodiment of the present invention, comprises the following steps: receiving from at least one downlink carrier an uplink grant downlink control information (DCI) including a request for the channel state information; measuring the channel state information of at least one first type downlink carrier; and transmitting the measured channel state information on a physical uplink shared channel (PUSCH) resource indicated by the uplink grant DCI, wherein the downlink multicarriers comprise the first type downlink carrier and a second type downlink carrier, wherein the channel state information on the second type downlink carrier may not be transmitted.
