Downlink Interference Mitigation Scheme for Two-tier OFDMA Cellular Networks
In a two-tier cellular network, macrocells and femtocells coexist. Since femtocells use low transmission power and share network resources with macrocells, they are considered as one of the promising solutions to highly congested network environments. However, since femtocells are deployed in a selforganized manner without cell-planning, they cause severe downlink interference to macro users. T...
متن کاملDownlink Resource Allocation for Enhanced Inter-Cell Interference Coordination (eICIC) in Heterogeneous Cellular Networks
LTE network architectures frequently make use of both macrocells and small cells (e.g., micro-, pico-, or nanocells) to allocate resources in an optimal manner to serve the exponentially increasing traffic load of mobile users. These heterogeneous networks (HetNets) must jointly consider the dynamic load on the network and the relative spatial distances and corresponding channel qualities of po...
متن کاملDynamic Inter-Cell Interference Coordination in Cellular OFDMA Networks by
Inter-cell interference has been traditionally handled by fixed partition based reuse schemes since the beginning of cellular era. Although effective for the then voice oriented networks, it is insufficient for modern day data communications as aggressive reuse is needed to support high data-rates. Due to its potential for spectrum efficiency, studies on dynamic inter-cell interference coordina...
متن کاملA Multi-traffic Inter-cell Interference Coordination Scheme in Dense Cellular Networks
This paper proposes a novel semi-distributed and practical ICIC scheme based on the Almost Blank SubFrame (ABSF) approach specified by 3GPP. We define two mathematical programming problems for the cases of guaranteed and besteffort traffic, and use game theory to study the properties of the derived ICIC distributed schemes, which are compared in detail against unaffordable centralized schemes. ...
متن کاملCentralized Inter-Cell Interference Coordination Using Multi-Band 3D Beam-Switching in Cellular Networks
The deployment of small cells is one of the most effective means to cope with the traffic explosion of cellular mobile systems. However, a small cell system increases the inter-cell interference, which limits the capacity and degrades the cell-edge user throughput. Inter-cell interference coordination (ICIC), such as fractional frequency reuse (FFR), is a well-known scheme that autonomously mit...
