“…In [9], two categories of interference graphs are introduced. One is called conflict graph [10], where the edges are the notion of critical interference. Two vertices of such graph can only have a connecting edge when one imposes interference on the other and vice versa.…”

We present a novel graph-based resource allocation and interference coordination framework to mitigate downlink interference in small cell networks. In our scheme, two types of clusters from the original network are generated, namely cell-cluster and user-cluster. We first divide small cells into cell-clusters according to their neighboring relationships in the network and examine the network morphology under different neighborhood bounds. Then we develop another graph clustering scheme to group the users in each cell-cluster into user-clusters with minimum intra-cluster interference. Finally, we employ a proportional fair scheduling scheme to assign subchannels among the user-clusters and allocate power using water-filling method. The simulation results show that our method achieves a significant improvement in spectral efficiency compared to previous works under both co-channel and orthogonal deployments.

“…The following expression shows the relation between SINR and corresponding spectral efficiency: (11) where γ is the average SINR seen on a RB and η is the spectral efficiency in bps/Hz. The parameter α is the attenuation factor with regard to the Shannon bound, S(γ) = log 2 (1 + γ).…”

Abstract-We study a dynamic inter-cell interference coordination scheme formulated using a novel binary integer linear programming optimization technique. The scheme aims to maximize utility, where different utility measures have been defined to model varying levels of user fairness. The formulated problem is decomposed into a number of smaller sub-problems and solved iteratively to ease the computational complexity. We observe the cell-edge and sector throughput as well as user fairness and compare with a reference scheme, where interference coordination is not used. It is observed that the proposed scheme always outperforms the reference scheme in terms of cell-edge and sector throughput as well as in fairness.
