Abstract [en]

For LTE networks, the levels of resource consumption of the cells, a.k.a. cell load factors, are coupled with each other in a non-linear manner. We establish theoretical and algorithmic results for the constrained load-coupling model. Our focus is on solution existence, i.e., whether or not a network configuration is able to support the traffic demand within the resource limit. We provide theoretical characterizations and concepts for determining feasibility. The concepts are illustrated for maximum demand scaling. Empirical insights are gained via a heterogeneous LTE network scenario.
