摘要：
3GPP Long Term Evolution-Advanced (LTE-A) aims at enhancement of LTE performance in many respects including the system capacity and network coverage. This enhancement can be accomplished by heterogeneous networks (HetNets) where additional micro-nodes that require lower transmission power are efficiently deployed. More careful management of mobility and handover (HO) might be required in HetNets compared to homogeneous networks where all nodes require the same transmission power. In this article, we provide a technical overview of mobility and HO management for HetNets in LTE-A. Moreover, mobility performance of heterogeneous network is studied in terms of success handover probability in deployment of macrocell and picocell. The simulation results show that the success HO probability is depended on UE speed, TTT and the Macro-pico distance.
