Power control and RB allocation in cloud radio access networks

Abstract

In the LTE system the fractional power control and the universal frequency reuse have been targeted. The fractional power control approach decreases the inter-cell interference but may impact the throughput. The universal frequency reuse improve the spectrum efficiently but may increase the inter-cell interference. In this paper, a novel approach power control will be proposed, to avoid such throughput loss and combined with a novel approach resource block allocation based on genetic algorithm in cloud radio access network. The simulations results show that the performance of the proposed system is significantly improved with respect to universal frequency reuse.
