Conceptual radio resource management approach in LTE heterogeneous networks using small cells number variation

As a profound and evident future trend in the field of mobile communication technologies development, heterogeneous networks became one of the crucial points of interests in wireless networks industry and academic research societies. Considering heterogeneous networks as an inseparable concept from LTE networks nowadays, which remain at position of advanced cellular system, the researchers aim to observe and solve the possible problems of inter-cell interference from the aspect of radio resource management. Hence, the lattermost trends consider heterogeneous networks through the process of connecting energy-efficient small cells to macrocells, due to undeniable importance of energy-efficient solution deployment, which was briefly presented in this paper. Also, the combination of radio resource management and heterogeneous networks turned out to be a practical compound of modern telecommunication techniques and technologies which provides a huge spectrum of possibilities for improving telecommunication services with minimized costs and increased efficiency of the whole system. The concept of radio resource management used in this paper was practically tested by small cells number variation within LTE HetNet set up in NS3 simulation environment.
