“…The use of ABS patterns can help reduce the interference from macrocells to picocells. To achieve the maximum possible performance gain using eICIC, joint optimization in ABS patterns and CSB values is required [6]. However, by ceasing transmission at certain timeslots using ABS, the eICIC can reduce the proper utilization of macrocell resources.…”

Resource allocation mechanisms and management of inter-cell interference coordination (ICIC) are fundamental characteristics of the LTE-A network for achieving maximum capacity. Cell densification serves as a promising candidate solution for meeting the demand posed by mobile users, as well as optimizing coverage. However, the transmit power difference between the introduced picocells and the legacy macrocells essentially leads to challenges that limits system performance, especially for those users located at the edge of the cell. As a means of providing a clear understanding, the authors thus formulate the optimization problem as game theory, in order to maximize a modified utility function, which aims at making improvements on the eICIC. Based on exact potential game formulation, we optimize almost blank subframe (ABS) and cell selection bias (CSB) settings for both macrocells and picocells in a distributed manner. Simulation results illustrate important performance gains on the service fairness of the users, and especially for cell edge users, where the averaged throughput increases by up to 51%, when compared to eICIC optimization without our modified utility function.

Future generation cellular networks are expected to provide broad-band access to a continuously growing number of mobile users. The densification of cellular networks is necessary to increase their capacity and improve spectral efficiency, however, in these systems, ICI still represents a real challenge that limits system performance, especially for users located at the edge of the cell. This paper briefly reviews the ICIC techniques in the downlink LTE-A of mobile cellular networks as an approach to alleviate the impact of interference and improve performance. The simulation results show the advantages and limitations of the eICIC and FeICIC techniques compared to the model without interference control.

This paper addresses enhancing green network evolution by femto cell densification in LTE‐Advanced heterogeneous networks (LTE HetNets). Previously, spectral efficiency has been the key performance indicator, but because of increased atmospheric radiations nowadays, energy efficiency maximization has also become the major concern for network providers. A major cause of degradation in spectral efficiency and energy efficiency is intercell interference in co‐channel deployment. The key to improve spectral efficiency and energy efficiency in LTE‐HetNet is intercell interference mitigation. In this paper, we have analyzed LTE‐HetNet from indoor and outdoor perspectives. We have proposed an intelligent fuzzy‐based reduced power time‐domain resource partitioning scheme to mitigate the interference level of victim macro users. The proposed intelligent technique is also helpful to maintain the fairness among femto cell users, which has not been considered in many previous studies. The simulation results have shown that the proposed method improved the overall spectral efficiency and energy efficiency of the system.
