Abstract: An opportunistic packet scheduling apparatus and method in consideration of re-use of radio resources in a broadband wireless communication system using multi-hop relay are provided to improve the balance of distribution of radio resource. A current radio resource efficiency calculating unit(500) initializes the size of a maximum resource allocation in a resource re-use group and the size of resource allocation of each terminal of the resource re-use group by hop by using channel information reported by a user terminal and a repeater according to each terminal path, and calculates the efficiency of current radio resources of a corresponding user terminal path by reflecting whether or not resources used by a different BS(Base Station) or repeater within the resource re-use group. A scheduling priority index calculating unit(502) calculates a scheduling priority index at a ratio of an average radio resource efficiency of each user terminal and the efficiency of the current radio resources. A maximum priority index user selecting unit(504) selects a user terminal with the largest scheduling priority index, and performs scheduling on the selected user terminal.
