“…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).

“…This issue can be addressed by utilizing coordinated multipoint (CoMP) transmission techniques, in which joint transmission and joint detection are the two essential techniques deployed in the downlink and upink, respectively. To further enhance the performance of cell-edge users, RISs can be deployed to assist CoMP transmission, since they provide additional reconfigured propagation paths [2].…”
