The authors consider the problem of 2-node cooperation for cellular networks. In the considered system, a node and a cooperative relay are selected in a Proportionally Fair (PF) manner to transmit to the Base Station (BS), which uses the Maximal Ratio Combining (MRC) for reception. The proposed scheme integrates the PF criterion in selective cooperation to maximize the overall utility of all 2-node cooperative transmissions, and is called Proportionally Fair Selective Cooperation (PFSC). This technique does not require distributed space-time coding algorithms and its simplicity allows for immediate implementation in existing hardware.
