Apparatus and method for selection of relay station in broadband wireless communication system

A device for selecting a relay station in a broadband wireless communication system and a method thereof are provided to configure channel information fed back from a receiving port, by using indexes only of a relay station, thereby decreasing an overhead by reducing the quantity of feedback information. A channel estimator(211) estimates channel information with relay stations. An index arranger(213) arranges indexes of the relay stations according to the estimated channel information. A transmitter transmits information on the predetermined number of indexes to a transmission port among the arranged indexes. The channel information refers to a signal to noise ratio. The index arranger(213) arranges the indexes in descending order according to the signal to noise ratio.
