In this paper, we propose two spectrally efficient adaptive partial decode-and-forward (DF)cooperative communication schemes, which are adaptive partialrepetition DF with quantized feedback (APR-DF-QF) and adaptivepartial coded cooperation DF with quantized feedback (APCC-DF-QF).We assume the relay node only has partial channel-state information, which is obtainedvia an quantized feedback link. We use the so-called mutual information (MI)model to adaptively optimize the amount of data that need to beforwarded by the relay node under a given block-error-rateconstraint. Simulation results show that with the optimized feedback, the MI model can predict well theoptimal amount of information that needs to be forwarded by therelay node, and that the two proposed schemes can substantiallyincrease the spectral efficiency.
