In the present study self-backhauled small cells for LTE-Advanced (a particular kind of small cells with wireless backhauling) are analyzed from the energy efficiency point of view. We perform an assessment of system performances with respect to traditional homogeneous LTE-Advanced networks, not only in terms of capacity and energy consumption, but also(More)
This paper proposes a dynamic coordinated scheduling strategy among LTE-Advanced cells. We argue that in current networks dynamic coordinated scheduling is practically feasible only at small scales (e.g., three cells)., and we discuss how to optimally select which group of cells should be coordinated to reap the maximum coordination benefit, weighing the(More)
This paper shows how to improve the overall network performance (cell throughput, fairness, and energy efficiency) via centralized coordination of LTE-A cells. We first present optimization models for small-scale coordination (i.e., three cells). Then, we show that extending the same solution to a higher number of cells is generally unfeasible, due to both(More)
