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...
We consider the resource allocation problem in a resource-constrained system for OFDMA-based relay networks. In the resource-constrained system, our allocation strategy is based on economic aim to maximize the user satisfaction which means we can get the more profits. It is impossible to meet all the users' data rate requirement in the resource-constrained system. So we divide the users into two classes:...
