Abstract
Long term evolution (LTE) heterogeneous networkcan represent improvement of cell coverage and networkcapacity by adopting advanced physical layer techniques. Inheterogeneous network, one of the major challenges is thehandover decision between different eNBs. The utilization of thepicocells results to use more network resources and handoverprocedure. In this paper, we investigate the hysteresis marginand load balancing problem in a 3GPP LTE heterogeneousnetwork. Firstly, we consider A3 event, Hysteresis Margin (HM)and Cell Individual Offset (CIO) objectives are not fixed forevery cells. Then we analyze the complexity of the problem andpropose a practical algorithm which calculate adaptivehysteresis margin and load balancing in heterogeneous network.The results show that our algorithm can lead to significantlybetter performances, such as redundant handovers reductionand improvement of the network performance.
