| Abstract: | A joint routing and resource partitioning scheme were proposed to improve cell capacity and user throughput of cellular network enhanced with two-hop fixed relay nodes (FRNs). Radio resources are partitioned under a reuse partitioning based framework, which guarantees effective and efficient inter-cell interference management. At the same time, each mobile terminal was assigned a channel-dependent route by the routing controller, which tries to maximize the cell capacity under the constraint imposed by reuse partitioning. Intensive computer simulations demonstrate the performance superiority of the FRN enhanced cellular network employing this scheme in comparison with conventional network, as well as the validity of the channel-dependent routing mechanism. |
