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: An overview about evolution of UMTS core network is given in using Internet Protocol, adding IMS functionality and finally in complete new packet core of technology called long term evolution.
Abstract: A core network of UMTS has a very long development. The first version of core network corresponds to an improved GSM/GPRS core network. The interfaces are changed and later all conception. The main changes are in using Internet Protocol, adding IMS functionality and finally in complete new packet core of technology called long term evolution. From user point of view it means increasing bit rates from tens kbit/s to tens Mbit/s, offering multimedia services, access to Internet, etc. This paper gives an overview about evolution of UMTS core network.

TL;DR: In this paper, a clustered ad hoc network with virtual antenna array is investigated, and the nodes are modeled as a Poisson point process (PPP) to provide theoretical guidance on the network design.
Abstract: In this paper, a clustered ad hoc network with virtual antenna array is investigated. Considering the random distribution of the nodes in ad hoc networks, the nodes are modeled as a Poisson point process (PPP). Different from prior analyses, interference in the ad hoc network is taken into account. Outage probability and transmission capacity of a single-hop network are first derived, and the accuracy of the analytical results is verified by simulation results. It is found that the outage probability decays as $\Theta(\lambda_c^{-(2/\alpha)})$ , where $\lambda_c$ is the intensity of potential cooperative nodes, and $\alpha$ is the path-loss exponent. That is, the outage probability obeys an inverse- $\mbox{2}/\alpha$ law with the intensity of cooperative nodes $\lambda_c$ . Moreover, there exists a unique optimal packet transmission rate to maximize the transmission capacity, and the optimal rate is shown to be within a specific interval that is only related to a path-loss exponent. Finally, the analysis of transmission capacity is extended to a multihop network. The results show that multihop transmission is not beneficial to the transmission capacity, but it does improve the outage performance. The analytical results are meaningful and can provide theoretical guidance on the network design.

TL;DR: The changes that LTE will bring and network operations impacts on the CSBH are discussed and functionality for quality of service (QoS) trending projections are presented to manage traffic capacity and trigger the traffic control mechanisms, to protect network resources and improve the overall customer experience.
Abstract: LTE (Long Term Evolution) represents an emerging technology that will change how mobility service providers connect user devices to their infrastructure over IP networks. To support growing mobile broadband data loads, an all-IP Ethernet cell site backhaul (CSBH) network infrastructure will make possible real-time high bandwidth applications using mobiles. This paper discusses the changes that LTE will bring and examines network operations impacts on the CSBH. It also introduces operations support system solutions to address performance management (PM) to determine if impaired LTE service has occurred. This paper covers major aspects of system solutions, including: capabilities for auto-detection, root-cause analysis based on correlation algorithms, and traffic congestion control mechanisms. It also presents functionality for quality of service (QoS) trending projections to manage traffic capacity and trigger the traffic control mechanisms, to protect network resources and improve the overall customer experience.

TL;DR: A model for packet transmission and cost is provided and shows that dramatic energy save can be achieved by both mobile users and base stations, e.g., as much as 70% of the energy cost due to packet transmission at the base station.
Abstract: In this paper, we analyze the power save and its impact on web traffic performance when customers adopt the continuous connectivity paradigm. To this aim, we provide a model for packet transmission and cost. We model each mobile user's traffic with a realistic web traffic profile, and study the aggregate behavior of the users attached to a base station by means of a processor-shared queueing system. In particular, we evaluate user access delay, download time and expected economy of energy in the cell. The model is validated through packet-level simulations. Our model shows that dramatic energy save can be achieved by both mobile users and base stations, e.g., as much as 70% of the energy cost due to packet transmission at the base station.

TL;DR: The results of the simulation demonstrate that the proposed controller could effectively achieve desired performance under various imperfections of the practical communication network.
Abstract: This article proposes a $\Delta $ -Modulator ( $\Delta $ -M) based quantised output feedback controller for linear networked systems. The proposed $\Delta $ -M is essentially a 2-level quantiser, in contrast to some of the existing quantisers such as $2^{p}$ level ( $p \geq 1$ ) uniform-interval-nearest-neighbour quantiser, and offers various advantages which include lower design complexity, less noisy and lower cost. The three key components of the control system: the controller , the filter and the quantiser are designed to achieve the desired performance. The stability conditions of the $\Delta $ -M are derived and conditions for the existence of zig-zag behaviour in steady-state are determined. The performance of the proposed controller is illustrated through simulations considering practical communication network based on ZigBee protocol. The results of the simulation demonstrate that the proposed controller could effectively achieve desired performance under various imperfections of the practical communication network.
