Disclosed is a method for transmitting channel status information at a user equipment in a wireless communication system, which more particularly comprises the following steps: receiving a reference signal from a base station; generating at least one channel status information based on the reference signal; mapping the at least one channel status information to available subframes, based on a priority of the at least one channel status information; and transmitting the at least one channel status information to the base station using the available subframes, wherein, if an uplink transmission using a first available subframe of the available subframes is blocked and a first channel status information that is mapped to the first available subframe has priority over a second channel status information that is mapped to a second available subframe, which is a next available subframe of the first available subframe, the first channel status information is shifted to be mapped to the second available subframe.
