Deploying relay station in cellular network is a promising way to enhance network capacity and extend coverage with high cost efficiency. OFDM is a promising air-interference for next generation wireless systems. OFDMA-based relay network offers opportunities to further improve the system performance. In this paper, we consider resource allocation problem in wireless relay network. Spatial reuse among relay stations is investigated to further improve the system efficiency. We focus on the traffic balancing between the relay links and access links, while allocating resources fairly to both direct users and relay users. The problem becomes hard when jointly considered with spatial reuse. Simulation results show that our algorithm attains superior performance in terms of cell-edge and average throughput.
