“…However, overhead will occur at BS without continuous consumer input as the channel parameters alter over time. A new multiple access (B-OFDMA) biorthogonal frequency division system with the broad low-complexity Fourier transform fraction (FrFT) was proposed by Wang (2013). The variation of time and frequency is set at each BS in this scheme with multi-angle reuse (MADR).…”

“…OFDMA allows the dynamic allocation of subcarriers (called OFDMA traffic channel) to different users at different time instances. For example, it utilizes 15 KHz subcarriers in LTE, which can be grouped into Resource Blocks (RBs) with each having 12 subcarriers (Kim et al, 2010;Lei et al, 2007;Sheu et al, 2015;Taranetz et al, 2011;Wang, 2013). To implement these for FFR scheme, one of the ways to allocate these RBs is to allocate them in a sector (Guo & Suárez, 2020;Hambebo et al, 2014).…”

In recent years, several researchers have embraced fractional frequency (FF) reuse as a strategy for resolving the inter-cell and co-channel interferences of adjacent cells (ICI, CCI) as the number of wireless networks grows. This technique is focused on the cell division of two parts, the inner and the outer, which enables multiple frequency bands to be assigned. The frequency advantages can be completely used in each inner zone, since there is no inter-cell disturbance for consumers in inner regions. According to this effective usage of the frequency spectrum available, FF will reduce the interruption of the channel and improve device efficiency. This manuscript presents a comprehensive study of different mechanisms to select the optimal FF scheme based on the user throughput. The analysis was conducted in order to obtain the optimal internal and external range for the cells as well as the optimal frequency distribution between the areas of the FR, Fractional Frequency Reuse 1 (FFR1) and Fractional Frequency Reuse 2 (FFR2) and evaluating their outputs and their number of users. In detail the overall consumer efficiency through the configured frequency distribution is analyzed. The FFR is a resource allocation technique that can effectively mitigate inter-cell interference (ICI) in LTE based HetNets and it is a promising solution. The proposal also employs high number sectors in a cell, low interference and good frequency reuse. The processes are tested by way of multiple modeling simulations.

“…This avoidance is achieved by several approaches and techniques. For example, in [ 15 ], the authors propose a new method to determine a proper frequency operation for each one of the inner cell, outer cell, and femtocell, whereas in [ 16 ], the ICI cancellation is realized using the biorthogonal frequency division multiple access cellular system along with multiple angle division reuse scheme. Moreover, another technique is reported in [ 17 ]; it suggests a novel dynamic interference cancellation method based on two levels.…”

Nowadays, one of the most important challenges in heterogeneous networks is the connection consistency between the mobile station and the base stations. Furthermore, along the roaming process between the mobile station and the base station, the system performance degrades significantly due to the interferences from neighboring base stations, handovers to inaccurate base station and inappropriate technology selection. In this paper, several algorithms are proposed to improve mobile station performance and seamless mobility across the long-term evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX) technologies, along with a minimum number of redundant handovers. Firstly, the enhanced global positioning system (GPS) and the novel received signal strength (RSS) prediction approaches are suggested to predict the target base station accurately. Then, the multiple criteria with two thresholds algorithm is proposed to prioritize the selection between LTE and WiMAX as the target technology. In addition, this study also covers the intercell and cochannel interference reduction by adjusting the frequency reuse ratio 3 (FRR3) to work with LTE and WiMAX. The obtained results demonstrate high next base station prediction efficiency and high accuracy for both horizontal and vertical handovers. Moreover, the received signal strength is kept at levels higher than the threshold, while maintaining low connection cost and delay within acceptable levels. In order to highlight the combination of the proposed algorithms' performance, it is compared with the existing RSS and multiple criteria handover decision algorithms.
