Abstract: This very up-to-date and practical book, written by engineers working closely in 3GPP, gives insight into the newest technologies and standards adopted by 3GPP, with detailed explanations of the specific solutions chosen and their implementation in HSPA and LTE. The key technologies presented include multi-carrier transmission, advanced single-carrier transmission, advanced receivers, OFDM, MIMO and adaptive antenna solutions, advanced radio resource management and protocols, and different radio network architectures. Their role and use in the context of mobile broadband access in general is explained. Both a high-level overview and more detailed step-by-step explanations of HSPA and LTE implementation are given. An overview of other related systems such as TD SCDMA, CDMA2000, and WIMAX is also provided.This is a 'must-have' resource for engineers and other professionals working with cellular or wireless broadband technologies who need to know how to utilize the new technology to stay ahead of the competition.The authors of the book all work at Ericsson Research and are deeply involved in 3G development and standardisation since the early days of 3G research. They are leading experts in the field and are today still actively contributing to the standardisation of both HSPA and LTE within 3GPP. * Gives the first explanation of the radio access technologies and key international standards for moving to the next stage of 3G evolution: fully operational mobile broadband* Describes the new technologies selected by the 3GPP to realise High Speed Packet Access (HSPA) and Long Term Evolution (LTE) for mobile broadband * Gives both higher-level overviews and detailed explanations of HSPA and LTE as specified by 3GPP

TL;DR: A comprehensive survey of most relevant research activities for content delivery acceleration in mobile networks, and provides a comprehensive reference for further research in this field.
Abstract: Owing to the imminent fixed mobile convergence, Internet applications are frequently accessed through mobile devices. Given limited bandwidth and unreliable wireless channels, content delivery in mobile networks usually experiences long delay. To accelerate content delivery in mobile networks, many solutions have been proposed. In this paper, we present a comprehensive survey of most relevant research activities for content delivery acceleration in mobile networks. We first investigate the live network measurements, and identify the network obstacles that dominate the content delivery delays. Then, we classify existing content delivery acceleration solutions in mobile networks into three categories: mobile system evolution, content and network optimization, and mobile data offloading, and provide an overview of available solutions in each category. Finally, we survey the content delivery acceleration solutions tailored for web content delivery and multimedia delivery. For web content delivery acceleration, we overview existing web content delivery systems and summarize their features. For multimedia delivery acceleration, we focus on accelerating HTTP-based adaptive streaming while briefly review other multimedia delivery acceleration solutions. This paper presents a timely survey on content delivery acceleration in mobile networks, and provides a comprehensive reference for further research in this field.

TL;DR: This paper addresses the problem of ICIC in the downlink of cellular OFDMA (LTE and WiMAX) systems in the context of Self-Organizing Networks (SON) in a cooperative MultiAgent control problem.
Abstract: Inter-Cell Interference Coordination (ICIC) is commonly identified as a key radio resource management mechanism to enhance system performance of 4G networks. This paper addresses the problem of ICIC in the downlink of cellular OFDMA (LTE and WiMAX) systems in the context of Self-Organizing Networks (SON). The problem is posed as a cooperative MultiAgent control problem. Each base station is an agent that dynamically changes power masks on a subset of its bandwidth to control interference it produces to its neighbouring cells. The agent learns the optimal coordinated power allocation strategy using information from its own and its neighbouring cells. A Fuzzy Inference System (FIS) is used to handle continuous state space defined by the input quality indicators to the controller performing the ICIC. The FIS is optimized using Reinforcement Learning (RL) with a Fuzzy Q-Learning (FQL) implementation. Simulation results illustrate the important performance gain brought about by the proposed ICIC scheme.

TL;DR: Simulation results show that expanded region picocells supported by the proposed cooperative macrocell-picocell scheduling approach are able to mitigate UE outages and significantly improve spatial reuse of spectrum.
Abstract: Because following current cell selection procedures, User Equipments (UEs) connect to the cell that provides the strongest DownLink (DL) Received Signal Strength (RSS), in a Heterogeneous Network (HetNet) comprised of macrocells and picocells, the large difference in DL transmit powers among macro Base Stations (BSs) and pico BSs may significantly reduce the DL service coverage area of picocells. In order to expand the DL coverage of picocells in the presence of macrocells, the concept of range expansion has been recently proposed, in which a positive offset is added to the DL RSSs of picocell pilot signals to increase their DL footprints. Although range expansion may increase the DL coverage of picocells, it may also create significant DL inter-cell interference in the Expanded Region (ER) of picocells, since pico ER UEs do not connect to the cells that provide the strongest DL RSSs. In this paper, we propose a novel cooperative macrocell-picocell scheduling approach to mitigate macrocell DL inter-cell interference towards pico ER UEs. Simulation results show that expanded region picocells supported by the proposed cooperative macrocell-picocell scheduling approach are able to mitigate UE outages and significantly improve spatial reuse of spectrum.

TL;DR: This work proposes a new small-cell architecture which reconfigures topologies and frequency bands, adapting to changing traffic demands and interference-mitigating requirements, and is significantly more efficient compared with current architectures.
Abstract: Small cells are an emerging approach to improving hotspots throughput in cellular networks. Unfortunately, they cannot be deployed in a large scale under current cellular architectures, because of a severe interference problem and inefficient use of spectrum. We propose a new small-cell architecture which reconfigures topologies and frequency bands, adapting to changing traffic demands and interference-mitigating requirements. The new architecture consists of distributed small-cell nodes (SCN) and co-located baseband units (BBU), and adaptively switches the connections between the SCNs and BBUs. The BBUs can even be shared among multiple SCNs that use different frequency bands. Our architecture requires fewer BBUs, and the spectrum and energy utilization is significantly more efficient compared with current architectures. Simulations show that the new architecture is able to increase the spectrum utilization by 23.5%, and improve the network satisfaction regarding traffic demands by 144.2% for small cells covering 0.5 km2. Our architecture can also reduce the investment and energy consumption of the BBUs by up to 40%.
