Optimisation of FeICIC for energy efficiency and spectrum efficiency in LTE-advanced HetNets

Until recently, spectral efficiency (SE) has been considered as the major key performance indicator of cellular networks. Nowadays, green evolution is becoming a major trend and the telecom industry is concerned about the energy costs and carbon footprint of their network infrastructure. These concerns will get more critical in the future due to the increasing base station densities. In such a sce...
