Interferences and Solutions in Long Term Evolution (LTE) Network: A Review
Keywords:Cross-Tier Interference, Co-Channel Interference, Heterogeneous Network, Inter-Cell Interference, LTE,
AbstractLTE is an enhanced of Universal Mobile Telecommunications Systems (UMTS) network, enriched with new and outstanding features geared towards its network and mobile users. Hence, it can improve poor network coverage and quality of service (QoS). Improper network designed by network operators and random deployments of femtocell behaviour will attract interferences and severely degraded the LTE network. This paper reviewed several interference management techniques to improve LTE network performances based on Third Generation Partnership Project (3GPP) in Rel-8 until Rel-12 from recent studies. This paper covers several interferences i.e. co-channel interference (CCI), cross-tier interference and inter-cell interference (ICI). The techniques reviewed focus on victim users e.g. at cell-edge and indoor areas in heterogeneous networks (HetNets). All techniques were explained and the variables used were reviewed.
