“…However, with the purpose of fully benefit from LTE-A HetNet deployments, the main challenges for comprises interference. Power control, resource partitioning, hardware centric, frequency reuse,adaptive frequency reuse techniques were proposed to mitigate the interference (Himayat et al, 2010;Mehmet et al, 2009;Jun et al, 2012;Chandrasekhar et al, 2008;Lopez-Perez, 2009;Gen et al, 2010;Suzan et al, 2009;Jun et al, 2012;Zheng et al, 2010). The details of these techniques are analyzed in this section with the performance analysis.…”

“…Furthermore, Rahman et al (2009) has explained a Fixed Frequency Reuse scheme (FFR), which is competent for local area scenarios in the LTE-A system; though the restrictions on the frequency bandwidth reduce the spectrum efficiency. Suzan et al (2009) has represented novel Adaptive Fractional Frequency Reuse scheme (AFFR) for multicell OFDMA based IEEE 802.16e network, where it is managed and operated by the Access Service Network Gateway (ASN-GW), which coordinates cluster. The cell area is virtually sorted to make the radio resources into the Fractional Frequency Reuse (FFR) zone where the users are suffering from high Inter-Cell Interference, ICI, from the neighboring cells and the Full Usage (FU) area where Inter-Cell Interference ICI is avoided.…”

Deploying femtocell in heterogeneous network (HetNets) are promising because of improved coverage as well as system capacity. The challenge for inter-cell and intra-cell interference has taken seriously by the industry. However, some distinctive characteristics presents key problem to mitigate the interference. The random deployment of femtocell (HeNodeB) and other small cell in HetNet becomes a key considerations issue because of interference which lead the performance degradation. The interference occurs between HeNodeB-to-macro cell and HeNodeB-to-HeNodeB in the case of uplink/downlink with the user equipments. Consequently, researchers have proposed some techniques to take over the interference in HetNet which need to be investigate, identify, quantify along with solution. Therefore, the aim of this study to evaluate the performance of potential interference alleviation schemes/techniques in Orthogonal Frequency Division Multiple Access (OFDMA) considering HetNets uplink/downlink scenario.

“…The disadvantage of such schemes lies in their scarce flexibility to adapt to changing cell load conditions. A scheme proposed in [10] suggests to divide the cell into two zones, namely edge and center, and assigns users to each zone dynamically based on their channel state information; however, the gain is limited due to the low number of available frequency bandwidths. Although originally proposed for WiMAX systems, RADION represents another valid approach to intercell interference mitigation [11].…”

The increasing demand for higher data rates in cellular network results in increasing network density. As a consequence, inter-cell interference is becoming the most serious obstacle towards spectral efficiency. Therefore, considering that radio resources are limited and expensive, new techniques are required for efficient radio resource allocation in next generation cellular networks. In this paper, we propose a pure frequency reuse 1 scheme based on base station scheduling rather than the commonly adopted user scheduling. In particular, we formulate a base station scheduling problem to determine which base stations can be scheduled to simultaneously transmit, without causing excessive interference to any user of any of the scheduled base stations. We show that finding the optimal base station scheduling is NP-hard, and formulate the BASICS (BAse Station InterCell Scheduling) algorithm, a novel heuristic to approximate the optimal solution at low complexity cost. The proposed algorithm is in line with the ABSF (almost blank sub-frame) technique recently standardized at the 3GPP. By means of numerical and packet-level simulations, we prove the effectiveness and superiority of BASICS as compared to the state of the art of inter-cell interference mitigation schemes.

“…It does not require prior frequency planning, but it does demand a huge amount of information exchange between neighboring cells. The third scheme is known as semi-static ICIC [6,7]. It operates at a centralized node in a centralized manner and entails a lot of information exchange.…”

In multicellular wireless networks, intercell interference limits system performance, especially cell edge user performance. One promising approach to solve this problem is the intercell interference coordination (ICIC) scheme. In this paper, we propose a new ICIC scheme based on a resource partitioning approach to enhance cell edge user performance in a wireless multicellular system. The most important feature of the proposed scheme is that the algorithm is performed at each base station in a distributed manner and therefore minimizes the required information exchange between neighboring base stations. The proposed scheme has benefits in a practical environment where the traffic load distribution is not uniform among base stations and the backhaul capacity between the base stations is limited.
