Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  consider a MIMO relay downlink system using beamforming techniques with quantized channel state information (CSI) feedback from two hop channels. With this scheme, each remote user feeds back its quantized CSI to the relay, and the relay sends the quantized beamforming vectors to the base station (BS). An upper bound on the rate loss due to feedback quantization is first characterized. Then, a strategy of scaling the quantization accuracy of both hop links in order to maintain the rate loss within a predetermined gap for growing SNRs is proposed. It is revealed that the numbers of feedback bits of both links should scale linearly with the transmit por at the relay, while the number of feedback bits from the relay to the BS needs to grow with the transmit por at the BS.
