Description: Efficient radio resource allocation in cellular systems envisages the assignment of the number of subcarriers and relative transmission format on the basis of link quality. Traditional schemes have approached this problem mainly focusing on resources within a cell and to large extent ignoring effects of multi-cell architecture.  In this paper we propose an optimum centralized radio resource allocator for the multi-cell scenario of cellular system which allows to highly out-performing iterative decentralized allocation strategies based on local optimization criteria. Simulation results show significant improvement in the resource utilization and overall network performance. Results show that maintaining cell interference within a margin instead of a hard target can significantly improve resource utilization.
