Abstract
The next generation of cellular networks is based on the concept of autonomous infrastructure deployment. Deploying femtocells inside a macrocell in a cellular network can significantly increase the macrocell’s capacity in terms of network optimization. However, the deployment of many femtocells within a macrocell’s coverage area causes severe femto-femto interference, or macro-femto interference, which may have an impact on the overall performance of femtocells. Avoiding interference is very important for co-tier or cross-tier femtocells and macrocells. In this paper, we propose a femtocell resource allocation scheme to alleviate the problem of co-tier or cross-tier interference. In the proposed scheme, orthogonal avoid interference with other femtocells. This paper studies a framework for autonomous network optimization based on the method of cognitive interference management to decrease the system’s capacity. Results showed improvement in femtocell QOS.
