Conceptual Verification of Integrated Heterogeneous Network Based on 5G Millimeter Wave Use in Gymnasium

Abstract

Aiming at the problem that the optical link may be too expensive or even impossible to achieve in a large number of locations in the central part of the backhaul line, the proof-of-concept (PoC) verification of a millimeter-wave integrated heterogeneous network (HetNet) is proposed. HetNet includes a traditional macrocell network and a new small unit that uses a millimeter wave for backhaul line and link access. The concept of a segmentation control plane and user plane was introduced. In the HetNet integrated millimeter wave, the control plane and the user plane were segmented to support the uninterrupted connection and enhance the capacity of the millimeter wave small base station. Millimeter wave communication could be used not only for access links, but also for wireless backhaul links, which will facilitate the installation of small millimeter wave cells. Through conceptual verification (PoC), the feasibility of millimeter-wave integrated HetNet prototype with millimeter wave technology used for return lines and link access is proved.(71-86 GHz) transceiver that supports 10-Gbps backhaul lines to form a centralized radio frequency access network (C-RAN) [13][14][15]. The literature [16] proposed an optimization scheme that adopts integrated optimization ideas so that various optimization mechanisms can work cooperatively, which improves optimization efficiency by repeated utilization of network resources and information. The analog simulation results also verify the effectiveness of the optimization scheme. The related literature studies the selection and switching of ultra-dense heterogeneous networks in 5G wireless communication systems. This paper proposes a joint vertical handover method based on region-aware Bayesian decision-making, which is optimized by selecting ultra-dense heterogeneous access networks, and switching the probability to solve the problem of ultra-dense network handover. By simulating and analyzing mobile users from macro base stations entering ultra-dense service cells and different scenarios of intra-cell and inter-cell mobility, the method can accurately select the network to be switched. Thus, this solution can be applied to the application scenarios of ultra-dense networks.This paper presents a proof-of-concept (PoC) of millimeter-wave integrated HetNet. The study looks at millimeter-wave technology in HetNet, especially the effective utilization of 60-GHz technology. HetNet includes a traditional macrocellular network and new junior units that use millimeter waves for backhaul and link access. In addition, the concept of split control plane (CP) and user plane (UP) is introduced in HetNet [17-20]. In CP/UP split HetNet, the traditional macrocell provides the CP with a large area coverage, while UP data is provided by the millimeter wave junior unit. This architecture supports uninterrupted connectivity and increases capacity by leveraging the advantages of both macro and junior cells.

A Multi-Layer Multi-Timescale Network Utility Maximization Framework for the SDN-Based LayBack Architecture Enabling Wireless Backhaul Resource Sharing

“…Sudden demand surges for backhaul capacity from the wireless devices and the corresponding radio nodes, e.g., the LTE enhanced Node Bs (eNBs) and Wi-Fi access points (APs), of one operator may overwhelm the operator's backhaul capacity and result in poor service quality, and ultimately, reduced revenue. Overall, with the advances in the wireless transmission capacities, the backhaul has emerged as a critical bottleneck of novel high-capacity wireless networks, such as small cell networks and 5G networks [1][2][3][4][5][6][7].…”
