“…Thus, efficient interference mitigation is the key to maximize capacity utilization. As a result, for interference mitigation and efficient resource allocation in the wireless cellular network, there has been an ample body of research . Across all these works, the common theme is that they aim to jointly allocate resources while employing efficient power control mechanism in the PHY layers to limit interference.…”

“…25 Interference alignment is another approach that has been proposed in the literature for multiple antenna (MIMO) systems. 17,[20][21][22][23][24][25][26] The idea of interference alignment is to coordinate multiple transmitters so that their mutual interference aligns at the receivers, facilitating simple interference cancelation techniques. This potentially improves the spectral efficiency and leads to exploitation of maximum possible degree of freedom (DOF) of multiuser wireless systems.…”

Mobile applications and social networks tend to enhance the needs for high‐quality content access. To address the expeditious growing demand for data services in 5G cellular networks, it is important to develop distribution techniques and an efficient content caching, aiming to significantly reduce redundant data transmission and, thus, improve the efficiency of the networks. In modern communication systems, caching has emerged as a vital tool for reducing peak data rates. It is anticipated that energy harvesting and self‐powered small base stations are the fundamental part of next‐generation cellular networks. However, uncertainties in energy are the main reason to adopt energy efficient power control schemes to reduce SBS energy consumption and ensure the quality of services for users. Using the edge cooperative caching such as energy efficient design can also be achievable, which reduces the usage of the capacity limited SBSs backhaul and the energy consumption. To support the huge power demand of cellular network, renewable energy harvesting technologies can be leveraged. In addition to this, power supply to the infrastructures is the main challenge to the mobile network operators (MNOs) especially in terms of economic optimum, sustainability, and green energy in developing countries for the growth of cellular networks. Renewable energy–based solutions for MNOs not only reduce the overall carbon dioxide emissions but also provide numerous profits.

“…In [2], the sub-channel allocation scheme for orthogonal frequency division multiplexing access (OFDMA) system in Long Term Evolution (LTE) downlink is applied by considering the contiguous resource blocks (RBs) when the available resources are more than FUEs. The contiguous RBs allocation in [3] is performed to increase the femtocell throughput, however, RBs are still remained at the end of the assignment process.…”

Abstract. We study a novel resources allocation approach for femtocells according to the quantity of femtocells and available channels in cognitive heterogeneous network. Due to the co-channel manner in macrocells and femtocells, femtocell base station (FBS) is combined with cognitive radio to obtain available spectrum resources and protect macrocell users (MUEs) from interference of femtocells. Then, the proposed channel allocation approach improves the throughput of femtocells and mitigates the co-tier interference among femtocells. Numerical results verify the conclusions.
