In this paper, we study the subcarrier allocation problem consider both with subcarrier allocation dynamic frequency reuse in the OFDMA-based relay networks. Firstly, we allocate the subcarriers to the relay stations and direct link users in the first hop. Then, we reuse the subcarriers that allocated to the relay stations in the second hop. Thirdly, we allocate the subcarriers to the relay link users in the decentralized scheme. We finally analyse the performance of our proposed resource allocation scheme, system throughput, the interference of the reused subcarriers, the computational complexity of the scheme. The numerical results show that our proposed resource allocation scheme can significantly improving the system throughput, reducing the computational complexity compared with a normal resource allocation scheme that do not consider with the frequency reuse.
