Book excerpt: Relaying is a potencial solution to improve the coverage and capacity in LTE-Networks. In this book is studied the radio resource management (RRM) in a case centralized for Relayed Enhacement LTE-Network for uplink considering the channel effects and the interferences provide by others UEs in the system. For this study are compared several aspects like SINR or the throughtput between a scenario with relaying and another without relaying, considering a LTE-Uplink Fractional Power Control and a RRM based on a matrix algorithm which use a priority metric based on Time Domain Proportional-Fair (TD-PF).

Book Synopsis Radio Resource Management in LTE Networks by : Hana Jouini

Download or read book Radio Resource Management in LTE Networks written by Hana Jouini. This book was released on 2017. Available in PDF, EPUB and Kindle. Book excerpt: High demands on mobile networks provide a fresh opportunity to migrate towardsmulti-tier deployments, denoted as heterogeneous network (HetNet), involving a mix of cell types and radio access technologies working together seamlessly. In this context, network optimisation functionalities such as load balancing have to be properly engineered so that HetNet benefit are fully exploited. This dissertation aims to develop tractable frameworks to model and analyze load balancing dynamics while incorporating the heterogeneous nature of cellular networks. In this context we investigate and analyze a class of load balancingstrategies, namely adaptive handover based load balancing strategies. These latter were firstly studied under the general heading of stochastic networks using independent and homogeneous Poisson point processes based network model. We propose a baseline model to characterize rate coverage and handover signalling in K-tier HetNet with a general maximum power based cell association and adaptive handover strategies. Tiers differ in terms of deployment density and cells characteristics (i.e. transmit power, bandwidth, and path loss exponent). One of the main outcomes is demonstrating the impact of offloading traffic from macro- to small-tier. This impact was studied in terms of rate coverage and HO signalling. Results show that enhancement in rate coverage is penalized by HO signalling overhead. Then appropriate algorithms of LB based adaptive HO are designed and their performance is evaluated by means of extensive system level simulations. These latter are conducted in 3GPP defined scenarios, including representation of mobility procedures in both connectedstate. Simulation results show that the proposed LB algorithms ensure performance enhancement in terms of network throughput, packet loss ratio, fairness and HO signalling.

Book Synopsis Resource Management for Heterogeneous Networks in LTE Systems by : Rose Qingyang Hu

Download or read book Resource Management for Heterogeneous Networks in LTE Systems written by Rose Qingyang Hu. This book was released on 2014-03-21. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief provides an in-depth look at the key issues that affect the performance of heterogeneous networks and presents schemes that can effectively tackle these issues. In particular, this book discusses unbalanced traffic load among the macro and micro Base Stations (BSs) caused by the transmit power disparity, and a load-balancing based mobile association scheme to balance the traffic load among the macro and micro BSs. This book also introduces a fractional frequency reuse (FFR) scheme with proper power control to help reduce interference at the UEs which are most vulnerable to such intra-cell interference. The last section investigates radio resource allocation issues for heterogeneous networks with cooperative relays, and proposes a resource allocation framework that could achieve proportional fairness among the UEs. Numerical results are provided to demonstrate the effectiveness of the proposed solutions in tackling the problem and improving network performance. Resource Management for Heterogeneous Networks in LTE-A Systems is designed for researchers and professionals working in networking and resource management. The content is also valuable for advanced-level students in computer science and electrical engineering.

Download or read book Practical Radio Resource Management in Wireless Systems written by Sofoklis A. Kyriazakos. This book was released on 2004. Available in PDF, EPUB and Kindle. Book excerpt: Despite frustrating customers and loss of revenue for telecommunications providers, cellular network congestion has remained a problem for which few solutions have been found. Covering GSM, GPRS, UMTS and beyond 3G systems, this practical book breaks new ground by providing you with proven techniques for decreasing blocking and dropped call rate due to network congestion. Using real measurements, this book clearly shows you that the maximum traffic that can be accommodated in a wireless network is not a constant value and varies significantly.
