Abstract
We consider the downlink of a cellular system based on the spatial channel model of the 3GPP MIMO urban macro cell with multiple antenna base stations and single antenna mobile devices. We analyze the impact of path-loss and intercell interference and classify mobile devices according to their location in a cell. We discuss non-cooperative approaches for maximizing the network sum-rate and propose an algorithm that combines altruistic avoidance of intercell interference and egoistic sum-rate maximization. The sum-rate reached with this algorithm is still limited by intercell interference but outperforms existing non-cooperative methods without introducing a large overhead.
