This book was released on 2013-07-17 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Device-to-Device (D2D) communication will become a key feature supported by next generation cellular networks, a topic of enormous importance to modern communication. Currently, D2D serves as an underlay to the cellular network as a means to increase spectral efficiency. Although D2D communication brings large benefits in terms of system capacity, it also causes interference as well as increased computation complexity to cellular networks as a result of spectrum sharing. Thus, efficient resource management must be performed to guarantee a target performance level of cellular communication. This brief presents the state-of-the-art research on resource management for D2D communication underlaying cellular networks. Those who work with D2D communication will use this book’s information to help ensure their work is as efficient as possible. Along with the survey of existing work, this book also includes the fundamental theories, key techniques, and applications.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of mobile wireless data service continues to stimulate the investment and expansion of high-rate and bandwidth-efficient wireless network systems. High volume data traffics in modern wireless system can lead to network overload, congestion, and process delay, severely straining the limited resource and capability of cellular networks. As a result, new connection modes such as device-to-device (D2D) has emerged as potential means to alleviate traffic load on radio network controllers (RNC) and eNodeBs (eNBs). We investigated several technical aspects critical to D2D communications as an underlay within existing cellular networks. · Neighbor Discovery: One of the first steps in setting up D2D links involves pairing UEs that are in close proximity. This is accomplished during neighbor discovery process, where UEs will identify their neighbors for potential direct-link setup. To facilitate the deployment of D2D functionality to standard LTE cellular systems, it is necessary to explore neighbor discovery opportunities in existing LTE infrastructure. We developed neighbor discovery methods that are compatible with current protocols in 4G LTE networks. · Cochannel Interference Management: D2D communications can improve spectral efficiency of the cellular system by allowing D2D links share the same spectrum with cellular link. However, it also leads to a critical problem of interference management. As more advanced multi-antenna user equipment becomes widespread, precoding serves as an effective technique to combat cochannel interference. We proposed practical precoder selection strategies that utilize existing LTE codebook. To overcome channel estimation error, robust precoding techniques are further developed to guarantee cellular outage requirements within D2D underlaid cellular systems. · Resource Allocation: Resource allocation is an important topic for effective interference management across the network. For example, the eNB can allocate cellular resources to direct links that are far apart so as to reduce cochannel interference. We developed an efficient algorithm that optimizes resource allocation of D2D links across multiple D2D modes and cellular channels. With practical consideration of statistical CSI, we provided a general framework for optimizing channel and power allocation of D2D underlay with applicability to various channel fading models. Neighbor discovery, cochannel interference management and resource allocation are three successive, vital steps in setting up D2D communications in the cellular system. We proposed technical solutions to each phase with an emphasis on their compatibility with existing system architecture. Our study discloses huge potential of D2D as a practical solution to boost performances of cellular networks.

Download or read book Efficient Device to Device Communication Underlaying Heterogeneous Networks written by Xue Chen and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Device-to-Device communications have the great potential to bring significant performance boost to the conventional heterogeneous network by reusing cellular resources. In cellular networks, Device-to-Device communication is defined as two user equipments in a close range communicating directly with each other without going through the base station, thus offloading cellular traffic from cellular networks. In addition to improve network spectral efficiency, D2D communication can also improve energy efficiency and user experience. However, the co-existence of D2D communication on the same spectrum with cellular users can cause severe interference to the primary cellular users. Thus the performance of cellular users must be assured when supporting underlay D2D users. In this work, we have investigated cross-layer optimization, resource allocation and interference management schemes to improve user experience, system spectral efficiency and energy efficiency for D2D communication underlaying heterogeneous networks. By exploiting frequency reuse and multi-user diversity, this research work aims to design wireless system level algorithms to utilize the spectrum and energy resources efficiently in the next generation wireless heterogeneous network.
Download or read book Radio Resource Management for Relay Aided Device to Device Communication written by Monowar Hasan and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, performance of relay-assisted Device-to-device (D2D) communication is investigated where D2D traffic is carried through relay nodes. I develop resource management schemes to maximize end-to-end rate as well as conversing rate requirements for cellular and D2D UEs under total power constraint. I also develop a low-complexity distributed solution using the concept of message passing. Considering the uncertainties in wireless links (e.g., when interference from other relay nodes and the link gains are not exactly known), I extend the formulation using robust resource allocation techniques. In addition, a distributed solution approach using stable matching is developed to allocate radio resources in an efficient and computationally inexpensive way under the bounded channel uncertainties. Numerical results show that, there is a distance threshold beyond which relay-assisted D2D communication significantly improves network performance at the cost of small increase in end-to-end delay when compared to conventional approach.

This book was released on 2017-08-18 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth discussion on how to efficiently manage resources of heterogeneous wireless networks and how to design resource allocation algorithms to suit real world conditions. Efficiently managing resources of the networks is more crucial now, than ever before, to meet users’ rapidly increasing demand for higher data rates, better quality-of-service (QoS) and seamless coverage. Some of the techniques that can be incorporated within heterogeneous wireless networks to achieve this objective are interworking of the networks, user multi-homing and device-to-device (D2D) communication. Designing resource allocation algorithms to suit real world conditions is also important, as the algorithms should be deployable and perform well in real networks. For example, two of the conditions considered in this book are resource allocation intervals of different networks are different and small cell base stations have limited computational capacity. To address the first condition, resource allocation algorithms for interworking systems are designed to allocate resources of different networks at different time-scales. To address the second condition, resource allocation algorithms are designed to be able to run at cloud computing servers. More of such conditions, algorithms designed to suit these conditions, modeling techniques for various networks and performance analysis of the algorithms are discussed in the book. This book concludes with a discussion on the future research directions on the related fields of study. Advanced-level students focused on communication and networking will use this book as a study guide. Researchers and experts in the fields of networking, converged networks, small-cell networks, resource management, and interference management, as well as consultants working in network planning and optimization and managers, executives and network architects working in the networking industry will also find this book useful as a reference.
