“…As a departure from prior work, our approach considers the dynamic eICIC configuration problem of non-linear EH SWIPT and crosstier interference for UL and DL in dense IoT HetNets. For future, our work can be extend with NOMA Network with imperfect CSI [24], intelligent reflecting surface-aided coordinated multipoint [25] and the mobile edge computing with fairness [26] in dense IoT HetNets. The allocated resource for ABS from macrocell m on the UL…”

Interference management and power transfer can provide a significant improvement over the 5th generation mobile networks (5G) dense Internet of Things (IoT) heterogeneous networks (HetNets). In this paper, we present a novel approach to simultaneously manage inferences at the downlink (DL) and uplink (UL), and to identify opportunities for power transfer and additional UL transmissions integrated with existing protocols and infrastructures for enhanced inter-cell interference coordination (eICIC) protocol in dense IoT HetNets, while considering practical non-linear energy harvesting (EH) model. The design is formulated as the joint optimization of interference aware UL/DL decoupling, airtime resource allocation and energy transfer. The key insight of our algorithm is to translate the original, intractable joint-optimization problem into a problem space where a good approximate solution can be quickly found. We evaluate our scheme through theoretical analysis and simulation. The evaluation shows that our approach improves the system utility by over 20% compared to start-of-the-art in dense IoT HetNets. Compared to alternative schemes, our approach maintains the best user fairness and rate experience and can solve the problem in a fast and scalable way.Index Terms-Downlink/Uplink decoupling (DUDe), Enhanced inter-cell interference coordination (eICIC), Simultaneous wireless information and power transfer (SWIPT), Internet of Things (IoT), heterogeneous network (HetNet).

“…In [36] it has been shown that NOMA-based unmanned aerial vehicle (UAV) network compared to OMA-based UAV network could be a better choice concerning several performance metrics, such as EE and spectral efficiency (SE). [37] provided the analysis and techniques of EE optimization for NOMA-UAV networks subjected to imperfect channel state information (ICSI) and interference. According to [38], the wireless IoT network design with solar-powered UAV and NOMA could be a very useful tool to building a sustainable energy future where NOMA-based design aids with the joint problem of altitude control and stochastic control.…”

The fifth-generation (5G) of cellular technology is currently being deployed over the world. In the next decade of mobile networks, beyond 5G (B5G) cellular networks with the under-development advanced technology enablers are expected to be a fully developed system that could offer tremendous opportunities for both enterprises and society at large. B5G in more ambitious scenarios will be capable to facilitate much-improved performance with the significant upgrade of the key parameters such as massive connectivity, ultra-reliable and low latency (URLL), spectral efficiency (SE) and energy efficiency (EE). Equipping non-orthogonal multiple access (NOMA) with other key drivers will help to explore systems' applicability to cover a wide variety of applications to forge a path for future networks. NOMA empowers the networks with seamless connectivity and can provide a secure transmission strategy for the industrial internet of things (IIoT) anywhere and anytime. Despite being a promising candidate for B5G networks a comprehensive study that covers operating principles, fundamental features and technological feasibility of NOMA at mmWave massive MIMO communications is not available. To address this, a simulation-based comparative study between NOMA and orthogonal multiple access (OMA) techniques for mmWave massive multiple-input and multiple-output (MIMO) communications is presented with performance discussions and identifying technology gaps. Throughout the paper, aspects of operating principles, fundamental features and technological feasibility of NOMA are discussed. Also, it is demonstrated that NOMA not only has good adaptability but also can outperform other OMA techniques for mmWave massive MIMO communications. Some foreseeable challenges and future directions on applying NOMA to B5G networks are also provided.
