Abstract:
This paper investigates load balancing (LB) in a hexagonal LTE (Long Term Evolution) macro cellular deployment. Cost and gain of LB is evaluated by downlink (DL) system simulations in terms of increased resource expenses versus quality of service (QoS) enhancement. We focus on handover parameter adaptation as LB mechanism. A distributed SON (self-organizing network) algorithm is presented that is based on resource estimation for offloading of potential LB candidates. The LB potential is evaluated in dependence of the user distribution within the overloaded cells for three scenarios revealing a different degree of clustering of overloaded cells. The results show how such a clustering reduces the potential for LB. Also, LB potential is reduced w.r.t. traffic throughput by an increased user density at cell edge.
