Abstract:
1. A method for measuring channel quality information in a system transmitting a signal by using multiple component carriers, the method comprising: measuring a channel quality value of one or more component carriers allocated to a user equipment, among multiple component carriers that are used by a serving cell, to which the user equipment belongs; measuring a second channel quality value of one or more component carriers not allocated to the user equipment, among the multiple component carriers that are used by the serving cell, when the first channel quality value is less than a first threshold value; and measuring a third channel quality value of a specific component carrier of neighboring cell, when the second channel quality value is less than a second threshold value, wherein said measuring of the first, the second and the third channel quality values are performed in order of (1) the one or more component carriers allocated to a user equipment, (2) the one or more component carriers not allocated to the user equipment, and (3) the specific component carrier of the neighboring cell.
