Static Inter-Cell Interference Coordination Techniques for LTE Networks: A Fair Performance Assessment

Abstract

Abstract. This paper focuses in the analysis of 100% static and distributed inter-cell interference coordination techniques in the context of LTE networks. Several methods have been modeled and studied with the aim of deriving practical radio planning rules based on the joint effect of operational parameters and thresholds. The investigation places special emphasis on the efficiency vs. fairness tradeoff. Several metrics have been detected as interesting to allow not only the performance measurement from different point of view, but also to look at the effectiveness in the utilization of resources. Results show that similar levels of spectral efficiency can be achieved by means of a proper and accurate network tuning. On the other hand, interesting second order differences appear due to some inherent features of each approach. These can be exploited depending on the particular network operator needs.

Improving soft frequency reuse for realistic OFDMA-based cellular deployments

“…Baseline designs (benchmarks) against which comparative analysis were done corresponds to typical bandwidthand class-proportionality configurations that have been suggested/studied in related studies [3], [19].…”

“…The detailed configuration of each of these benchmarks is shown in Table II. The values were computed by following the guidelines in [3] and [19]. Figure 4 shows 3D and 2D visualizations of the Pareto front (X ) obtained by means of Algorithm 1.…”

A Survey on Inter-Cell Interference Coordination Techniques in OFDMA-Based Cellular Networks

“…Comparing the scheme's evaluation in realistic irregular cells conducted in [56] to the evaluation conducted on regular shaped cells in [55] led to the following conclusions:…”

“…In [55], With the increase of the number of user groups, the bandwidth allocated to each user group tends to decrease. (4) Effect of inter-class interference which is caused due to using the same band for different user classes at the different cells.…”

“…In [55] and [56], Gonzalez et al conducted a comparison among a number of static schemes to evaluate the performance of static ICIC schemes in regular cells and realistic irregular cells layouts.…”
