ABSTRACT
In future cellular system, it is becoming more challenging to optimize the radio resource management andmaximize the system capacity whilst meeting the required quality of service from user's point of view.Traditional schemes have approached this problem mainly focusing on resources within a cell and tolarge extent ignoring effects of multi-cell architecture. For multi-cell systems employing intra-cellorthogonal communication channels, inter-cell interference mitigation techniques are expected to be oneof the key radio resource management functions. In this paper, we propose a multi-cell coordinated andun-coordinated dynamic resource sharing algorithms and reuse techniques among base station/ relaystation cells. The sub carrier allocation and power allocation are performed on the basic of sum-ratemaximization, by considering the load over the cell (3-sector cell). The simulation results show theperformance comparison between both coordinated and un-coordinated resource allocation schemes withdifferent sum-rate maximization algorithms.
