Popis:	In this paper we present an adaptive radio resource management scheme for relay enhanced cells based on soft resource partitioning. Power masks varying in the time or frequency domain are assigned to each radio access point (RAP). Thus, soft resource partitioning enables frequency reuse one and at the same time each RAP has high power resources with reduced interference available to schedule user terminals. Our scheme allows a local power mask adaptation and we present a mechanism for adapting the power mask based on the traffic load situation within the REC. We show in dynamic system simulations for a metropolitan area scenario that the radio resource management scheme based on soft resource partitioning outperform a scheme based on hard resource partitioning. Further, we show that the adaptive resource management scheme improves the throughput of low throughput users in the cell.
