Resource Allocation for Throughput Enhancement in Cellular Shared Relay Networks

The downlink frame of a cellular relay network is considered, where a shared MIMO Decode-and-Froward relaying is used to serve the users at the edge of the cell. The relay employs zero-forcing beamforming to manage the interference among the Mobile Stations (MSs) at the edge of the cell. A non-cooperative scheme is considered where there is no coordination between the Base Stations (BSs) and the Relay Station (RS), and a power control algorithm for the RS is developed that maximizes the rate of the relayed users. A cooperative setting which allows the coordination of a power allocation between BSs and RSs is also considered.
