“…Recognizing the high potential of D2D communications, the 3GPP has recently included control plane and measurement support for physical‐layer broadcasting–based D2D communications . The 3GPP is currently studying the necessary physical‐layer enhancements for introducing physical‐layer unicast support for D2D communications in the future releases of Long‐Term Evolution (LTE) and New Radio networks . Indeed, physical‐layer unicast—that is, the D2D transmitter being aware of the intended receiver, as opposed to the currently supported broadcast communication—is needed to fully realize the gains expected from introducing D2D communications in a cellular spectrum.…”

Summary Device‐to‐device (D2D) communication in a cellular spectrum increases the spectral and energy efficiency of local communication sessions, while also taking advantage of accessing licensed spectrum and higher transmit power levels than when using unlicensed bands. To realize the potential benefits of D2D communications, appropriate mode selection algorithms that select between the cellular and D2D communication modes must be designed. On the other hand, physical‐layer network coding (NWC) at a cellular base station—which can be used without D2D capability—can also improve the spectral efficiency of a cellular network that carries local traffic. In this paper, we ask whether cellular networks should support D2D communications, physical‐layer NWC, or both. To this end, we study the performance of mode selection algorithms that can be used in cellular networks that use physical‐layer NWC and support D2D communications. We find that the joint application of D2D communication and NWC scheme yields additional gains compared with a network that implements only one of these schemes, provided that the network implements proper mode selection and resource allocation algorithms. We propose 2 mode selection schemes that aim to achieve high signal‐to‐interference‐plus‐noise ratio and spectral efficiency, respectively, and take into account the NWC and D2D capabilities of the network.

“…Moreover, at the intermediate relays in the communication path of a D2D multi-hop relay communication system, it takes non-negligible time to receive, process, and transmit data. Thus the more hops there are in the communication path, the larger latency in VNETs will be resulted in [13].…”

The development of intelligent transportation systems raises many requirements to the current vehicular networks. For instance, to ensure secure communications between vehicles, low latency, high connectivity and high data rate are required for vehicular networks. To meet such requirements, the 5G communication systems for vehicular networks should be improved accordingly. This article proposes a communication scheme for 5G vehicular networks, in which moving access points are deployed on vehicles to facilitate the access of vehicle users. Moreover, the adjacent vehicle-installed moving access points may cooperatively communicate with the vehicle users by joint transmissions and receptions.In this way, the vehicle users communicate with one or more unspecified cooperative access points in a cell-less manner instead of being associated to a single access point. To manage such cell-less networks, local moving software-defined cloudlets are adopted to perform transmission and scheduling management. Simulation results show that the proposed scheme significantly reduces the latency, while improving the connectivity of the vehicular networks, and can be considered as a research direction for the solution to 5G vehicular networks.Accepted by IEEE Wireless Communications SI on "Emerging Technology for 5G Enabled Vehicular Networks".Lijun Wang is with Wuhan University and Wenhua College; to deploy application services and network equipment close to the moving vehicles, such that the latency of network transmission and service response time can be reduced significantly.One of the important approaches to providing services close to the vehicles is the mobile edge computing scheme. By mobile edge computing, computing and storage resources are deployed at a variety of the edge network equipment to provide rapid services for mobile users [2]. Because of the high mobility of vehicles, the traditional mobile computing encounters challenges of efficient and rapid resource scheduling and allocation. Meanwhile, the approach to providing communication services close to the vehicles is to implement the access network among the vehicles themselves. Based on this as-close-as-possible deployment strategy, dynamic, open, self-organized, easy-deploying, and cost-effective VNETs can be realized instead of traditional monitoring-focused traffic assisting systems. Consequently, the study on new architectures of VNET is vital for the future development of intelligent transportation systems (ITSs).The concept of VNET grows out of an application of wireless sensor networks (WSNs), and in the early days of VNETs, many devices and protocols directly came from WSNs and mobile ad hoc networks (MANETs). However, because of the quick movement of vehicles, many existing protocols including ZigBee and Bluetooth are not suitable for VNETs anymore.In contrast, IEEE 802.11p and Long-Term Evolution (LTE) are recognized as two most important technologies for VNETs [3]. Based on these technologies, various architectures for VNETs have been developed. General...

“…In the distributed discovery design, optimal resources and legitimate transmission power are apportioned with the consent of base station. However, this strategy involves complex signaling overhead and multifaceted nature of multiple transmitters to be composed [4]. In contrast, centralized device discovery design is adequately controlled by the base station and resources are managed by center system.…”

In the fifth generation (5G), it is anticipated that device-to-device (D2D) operation will be locally incorporated as a part without any bounds. In D2D network, multiple devices coexisting is a challenging subject of device discovery. The device discovery is performed under a visually impaired situation such as channel information, location, and the number of devices. In this paper, centralized device discovery is chosen due to power consumption and signaling overhead of the distributed system. A distinctive approach for device discovery in an in-band cellular network, based on the device's power, is suggested with an efficient technique which enhances the implementation of D2D communication and improves the accomplishment by alleviating the discovery issues. The group of devices forms a lattice structure, and it is positioned in the coverage area. The hypersphere is constructed based on the power knowledge of a discoverer device which helps for accurate and fast device discovery in a lattice structure. Besides, sphere decoder like (SDL) algorithm is applied for quick and precise discovery in the lattice structure. Simulation results present the performance of the proposed QR factorized lattice structure scheme regarding device power, enhanced in the number of discovered devices and controlled signaling overhead.
