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

The present invention relates to a relay mode selecting method in a broadband wireless access communication system relates to the mode selected according to the user's RS base station receiving a respective bid value (bidding price) from the first relay station group by the base station in charge and comprising the step of the operation to the respective bid value and the first relay station group each process of determining the winner of a relay station of at least one of the auction based on the interference information and the at least one or more auction winner relay station in active mode the user, the bid value of the located within and characterized in that the difference between the numerical value and that is anticipated to have a relay station is improved after the reference value and the sub-carrier redistribution for each service of the user, the relay station area the user, using a relay station, depending on whether or not to go out to meet the user's current services, BS go out the best relay set value high visible improvement while Mitch less interference effects around the relay station is set to active mode, and the other relay station may increase the service requirement of the user by effectively to operate in a standby mode.
