Abstract：In recent years, the increasing of intelligent mobile terminals, such as smart phones and wireless devices have boost a domestic demand of higher performance of mobile communtctions, especially the demand for data and multimedia services anytime and anywhere. And the next generation of mobile communications system will emerge to provide large capacity and ubiquitous coverage to meet the requirements of higher rate, lower latency and higher spectrum efficiency. So how to overcome the traffic storm and improve the user experience with the limint reasource becomes more and more important. Cloud random access network can improve overall system performance with low power consumption and low cost, thus caused wide attention in academiaic study. In this paper, we proposes a method of resource allocation based on delay optimal in CRAN where the control actions are assumed to be a function of the instantaneous channel state information as well as the queue state information. Simulation results verified that our algorithm has achieved good performance with respect to the reduction in energy consumption and the improvement of capacity.
