摘要
This letter studies the effect of channel side information on the achievable rates of quasi-static fading channels. The side information is obtained via combination of the standard channel state information (CSI) and automatic repeat request (ARQ) feedback. Demonstrating the general rate optimization problem, the results are obtained for different power allocation strategies. Simulation results show that considerable rate increment is achieved with as low as one bit feedback for each of these approaches.
