Abstract:
LTE Heterogeneous networks introduced multiple low power base stations (Pico cell) i.e. relay nodes or
Remote Radio Heads in addition to High power cells (Macro cells) to increase the hotspot capacity and to provide the best
QoS and high data rates for the indoor as well as outdoor users. But due to multiple low power and high power cells working
on same frequency, there are several interference and handover issues come forward This paper comprises the research
conducted to address these issues. It includes the comprehensive survey about handover issues, existing handover management
techniques, effect of interference on Handover, their flaws and the future work required to address these issues. The
survey is performed to give a platform for finishing the gap between researchers and engineers for the better future of LTE
heterogeneous networks.
