1. A method of reporting channel characteristics of at least two component carriers to at least one base station in a wireless communication, the method comprising:
performing periodic channel state information (CSI) reporting regarding the at least two component carriers on at least two individually configured physical uplink control channels (PUCCHs),
wherein, in case that a collision between a first CSI report of a first report type on a first of the at least two PUCCHs and a second CSI report of a second report type on a second of the at least two PUCCHs occurs in a subframe,
if priorities allocated to the first report type of the first CSI report and the second report type of the second CSI report are different, the performing periodic CSI reporting comprises transmitting a CSI report having a higher priority among the first CSI report and the second CSI report, and
if priorities allocated to the first report type of the first CSI report and the second report type of the second CSI report are the same, the performing periodic CSI reporting comprises transmitting a CSI report corresponding to a primary cell among the first CSI report and the second CSI report,
wherein each of the priorities are determined based on classes to which the first CSI report and the second CSI report belong,
wherein the classes comprise a first class having a highest priority, a third class having a lowest priority, and a second class having a priority that is lower than the first class and is higher than the third class,
wherein the first class comprises: a type 2a report, a type 3 report, a type 5 report and a type 6 report,
wherein the second class comprises: a type 2 report, a type 2b report, a type 2c report and a type 4 report, and
wherein the third class comprises: a type 1 report and a type 1a report.
