Effective dynamic coordinated scheduling in LTE-Advanced networks

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 above choice with architectural considerations, such as cost-effectiveness and latency. Our results show that, if we take a single groups of coordinated cells and assume random, unpredictable interference, coordinating overlapping cells is the best choice. However, if we assume that neighboring group of cells do coordinate autonomously, the performance is less sensitive to the way we group them, hence architectural feasibility and cost make the difference.
