Abstract  Abstract

A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI) a first precoding matrix index (PMI) a second PMI and a channel quality indicator (CQI) for one or more downlink carriers the CQI being calculated based on precoding information determined by a combination of the first and second PMIs determining when two or more CSIs collide with one another in one uplink subframe of one uplink carrier a CSI to be transmitted on the basis of priority and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI the CSI including a wideband CQI or a subband CQI has low priority and is dropped.
