Abstract:
1. An apparatus for a Base Station (BS) in a relay type broadband wireless communication system, comprising: a sorter for generating a first index group in which indices of relay stations are sorted according to channel information between the BS and each relay station; a receiver for receiving a second index group in which the indices of the relay stations are sorted according to channel information between a Mobile Station (MS) and each relay station; and a selector for selecting a relay station to be used to communicate with the MS by using the first index group and the second index group, wherein the selector comprises: a generator for generating a search matrix by using the first index group and the second index group; and a searcher for searching for a relay station to be used according to the search matrix, wherein each element of the search matrix is determined based on a combination of an order of indices in the first index group and an order of indices in the second index group.
