Abstract:
5G (5th generation mobile networks or 5th generation wireless systems) is the next major phase of mobile telecommunications standards beyond the current 4G LTE (Long-Term Evolution) standards. 5G technology needs to be specified, developed, and deployed by a variety of industry players including network equipment vendors, network operators, semiconductor vendors, and device manufacturers. The scope of 5G will range from mobile phones to next-generation automobiles. Device to Device (D2D) Communication is regarded as a promising technology in 5G to provide low power, high data rate and low latency. Introducing D2D poses many challenges and risks to the longstanding cellular architecture, which is centred on the base station.

Abstract:
In recent years, the interest around Intelligent Transportation Systems (ITSs) has rapidly increased, and they are currently being deployed in commercial, industrial and residential domains. The Next-Generation Cooperative ITSs (C-ITSs) are expected to bring the paradigm of Mobility-as-a-Service (MaaS) to a whole new level. A crucial role to this is attributed to Connected and Autonomous Vehicles (CAVs), as the focus is steered from being autonomous systems to becoming cooperative entities. The cooperation between them is mainly enabled by sharing sensor data and manoeuvring intentions in a Vehicle-to-Everything (V2X) fashion. Thus, an efficient, reliable and robust communication plane between CAVs and the infrastructure network, able to accommodate the demanding exchange of sensor data, is of paramount importance. This thesis presents the author's work and contributions in the field of connectivity for CAVs within the scope of an ITS. As connectivity is a broad term, it can be examined from different perspectives. This thesis focuses on the design of a novel heterogeneous C-ITS framework that can handle scalable city-wide ITS application data streams. Later, it identifies the various drawbacks and limitations of the current Radio Access Technologies (RATs), and investigates ways to overcome them and improve the system performance. The contributions of this thesis commence with the introduction of a conceptual design of a city-scale C-ITS implementation. Briefly, this proposed system operates as a heterogeneous network, maps different application data streams on to different V2X layers, and employs different RATs to deliver each stream in a V2X manner. Based on this fundamental concept, various drawbacks are primarily identified on existing simulation models and tools for IEEE 802.11p. Later, the existing limitations are addressed by designing an experimental testbed and conducting a sizeable experimental campaign. This not only helps with the accurate calibration of the existing models, but also provides a deep comprehension of how a real-world large-scale implementation works. In the later parts of this thesis, the focus is directed towards Millimetre Waves (mmWaves), as is a competent technology for accommodating significant amounts of exchanged sensor data. At first,the beamforming problems in mobile environments are identified. They are approached through an intelligent MAC-layer solution for V2X beam steering. Furthermore, the resource allocation problem at the highly dynamic network topology of CAVs is investigated, designing a multi-link association scheme for V2V mmWave communications. Finally, the last research effort of this thesis, is related to the city-scale positioning of the mmWave Road-Side Units (RSUs), where an optimal automated procedure within an urban scenario is proposed. The thesis is concluded with the critical review of the research activities mentioned above as well as some ideas for future research.

Abstract:
The increasing demand for connectivity and broadband wireless access is leading to the fifth generation (5G) of cellular networks. The overall scope of 5G is greater in client width and diversity than in previous generations, requiring substantial changes to network topologies and air interfaces. This divergence from existing network designs is prompting a massive growth in research, with the U.S. government alone investing $400 million in advanced wireless technologies. 5G is projected to enable the connectivity of 20 billion devices by 2020, and dominate such areas as vehicular networking and the Internet of Things. However, many challenges exist to enable large scale deployment and general adoption of the cellular industries. In this dissertation, we propose three new additions to the literature to further the progression 5G development. These additions approach 5G from top down and bottom up perspectives considering interference modeling and physical layer prototyping. Heterogeneous deployments are considered from a purely analytical perspective, modeling co-channel interference between and among both macrocell and femtocell tiers. We further enhance these models with parameterized directional antennas and integrate them into a novel mixed point process study of the network. At the air interface, we examine Software-Defined Radio (SDR) development of physical link level simulations. First, we introduce a new algorithm acceleration framework for MATLAB, enabling real-time and concurrent applications. Extensible beyond SDR alone, this dataflow framework can provide application speedup for stream-based or data dependent processing. Furthermore, using SDRs we develop a localization testbed for dense deployments of 5G smallcells. Providing real-time tracking of targets using foundational direction of arrival estimation techniques, including a new OFDM based correlation implementation.

Abstract:
Avec la croissance rapide de la demande de trafic de données des clients, l'amélioration de la capacité du système et l'augmentation du débit des utilisateurs sont devenues des préoccupations essentielles pour le futur réseau de communication sans fil de cinquième génération. Dans ce contexte, la communication terminal-à-terminal (Device-to-Device D2D) et le Full Duplex (FD) sont proposés comme solutions potentielles pour augmenter l’efficacité spectrale et le débit des utilisateurs dans un réseau cellulaire. Le D2D permet à deux périphériques proches de communiquer sans participation de la station de base ou avec une participation limitée. D'autre part, la communication en FD permet une transmission et une réception simultanées dans la même bande de fréquence. En raison de la propriété de distance courte des liaisons D2D, exploiter la technologie FD dans la communication D2D est un excellent choix pour améliorer encore plus l’efficacité spectrale cellulaire et le débit des utilisateurs. Cependant, les émetteurs-récepteurs FD constituent de nouveau défis pour la communication D2D. Par exemple, en FD les émetteurs-récepteurs ne peuvent pas supprimer d’une manière parfaite l’auto-interférence (SI) générée au niveau des récepteurs lors de la transmission des données (par le propre émetteur du dispositif cellulaire). Ainsi, l’auto-interférence résiduelle qui est étroitement liée à la valeur de la puissance de l’émetteur affecte fortement les performances de la transmission FD. De plus, la technique en FD crée des interférences supplémentaires dans le réseau, ce qui peut dégrader ses performances par rapport à la transmission en semi-duplex (Half-duplex HD). Ainsi, une bonne gestion des ressources radio est nécessaire pour exploiter les avantages de la FD et garantir la qualité de service (QoS) des utilisateurs. Les travaux de cette thèse portent sur l'allocation de puissance et l'attribution de canaux d'un réseau FD-D2D. En particulier, cette thèse aborde d’abord le problème de l’allocation de puissance et propose une méthode d'allocation de puissance (PA) optimale centralisée simple mais efficace, puis développe le schéma optimal conjoint d’AP et d’AC pour un réseau FD-D2D. Un algorithme de complexité réduite CATPA, basé sur une allocation CA suivie d'une allocation PA, est aussi développée et proposé. La thèse présente à la fin une stratégie efficace d'AP décentralisée en utilisant les outils de la théorie des jeux
With the rapidly growing of the customers' data traffic demand, improving the system capacity and increasing the user throughput have become essential concerns for the future 5G wireless communication network. In this context, D2D communication and FD are proposed as potential solutions to increase the spatial spectrum utilization and the user rate in a cellular network. D2D allows two nearby devices to communicate without BS participation or with limited participation. On the other hand, FD communication enables simultaneous transmission and reception in the same frequency band. Due to the short distance property of D2D links, exploiting the FD technology in D2D communication is an excellent choice to further improve the cellular spectrum efficiency and the users’ throughput. However, practical FD transceivers add new challenges for D2D communication. For instance, the existing FD devices cannot perfectly eliminate the SI imposed on the receiver by the node’s own transmitter. Thus, the RSI which is tightly related to the transmitter power value highly affects the performance of FD transmission. Moreover, the FD technique creates additional interference in the network which may degrade its performance when compared with the half-duplex transmission. Thus, proper radio resource management is needed to exploit the benefits of FD and guarantee the QoS of the users. The works in this dissertation focus on the PA and CA of a FD-D2D network. In particular, this thesis first addresses the PA problem and proposes a simple yet efficient centralized optimal PA framework, and next, it derives the optimal joint PA and CA scheme for an FD-D2D network. A simple sub-optimal algorithm for resource allocation named CATPA, based on CA followed by PA, is also derived and proposed. This dissertation also develops, in the end, an efficient decentralized PA using game theory tools that will be an essential part of future works in the context of distributed radio resource management

Abstract:
Researchers all over the world are looking for ways of continuing the evolution of mobile communication technology to its fifth generation (5G). Providing high data rate information transfer to highly mobile users over time varying communication channels remains a shared obstacle. In this thesis, we contribute to these global efforts by providing further fundamental understanding of time varying channels in 5G mobile communication systems and overcome the obstacle. First, we reopen the door of research in the field of time varying communication channels. The door has almost been closed before by a well-accepted conclusion related to the types of channels. It was ‘proven’ that mutual information rate of the uniformly symmetric variable noise finite state Markov channel (USVNFSMC) was maximized by input signals of maximum information entropy. The result means time varying channels and time invariable channels are identical, regarding information rate maximization over input signal probability distribution. We provide evidence that assumptions for the results are not valid for time varying channels and replace them with more practical ones. We confirm, via input signals of non-uniform independent distribution and first order Markov chain, that the mutual information rate of the USVN-FSMC is maximized by input signals with information redundancy. Second, we provide a solution which dramatically reduces the waste of communication resources in estimating channel state information of time varying mobile communication channels. The orthodox method in dealing with time varying channels is that, the channel is “cut” to pieces in time domain to look like a sequence of time invariable channels for the purpose of state estimation. By doing this the capacity loss is staggering for n-times higher carrier frequency channels and n-dimensional multiple input and multiple output channels, eliminating almost entirely the capacity gain of these two most promising capacity-increasing techniques for 5G. We define the simplest finite state Markov model for time varying channels to explain the essential difference between information processing of time varying channels and time invariable channels. We prove that the full information capacity of the model can be achieved by the differential type encoding/decoding scheme without employing any conventional channel state estimator.

Abstract:
Massive Multiple-Input Multiple-Output (MIMO) wireless communication systems, equipped with tens or even hundreds of antennas, emerge as a promising technology for the Fifth Generation (5G) wireless communication networks. To design and evaluate the performance of massive MIMO wireless communication systems, it is essential to develop accurate, flexible, and efficient channel models which fully reflect the characteristics of massive MIMO channels. In this thesis, four massive MIMO channel models have been proposed. First, a novel non-stationary wideband multi-confocal ellipse Two-Dimensional (2-D) Geometry Based Stochastic Model (GBSM) for massive MIMO channels is proposed. Spherical wavefront is assumed in the proposed channel model, instead of the plane wavefront assumption used in conventional MIMO channel models. In addition, the Birth-Death (BD) process is incorporated into the proposed model to capture the dynamic properties of clusters on both the array and time axes. Second, we propose a novel theoretical non-stationary Three-Dimensional (3-D) wideband twin-cluster channel model for massive MIMO communication systems with carrier frequencies in the order of gigahertz (GHz). As the dimension of antenna arrays cannot be ignored for massive MIMO, nearfield effects instead of farfield effects are considered in the proposed model. These include the spherical wavefront assumption and a BD process to model non-stationary properties of clusters such as cluster appearance and disappearance on both the array and time axes. Third, a novel Kronecker Based Stochastic Model (KBSM) for massive MIMO channels is proposed. The proposed KBSM can not only capture antenna correlations but also the evolution of scatterer sets on the array axis. In addition, upper and lower bounds of KBSM channel capacities in both the high and low Signal-to-Noise Ratio (SNR) regimes are derived when the numbers of transmit and receive antennas are increasing unboundedly with a constant ratio. Finally, a novel unified framework of GBSMs for 5G wireless channels is proposed. The proposed 5G channel model framework aims at capturing key channel characteristics of certain 5G communication scenarios, such as massive MIMO systems, High Speed Train (HST) communications, Machine-to-Machine (M2M) communications, and Milli-meter Wave (mmWave) communications.

Abstract:
From the first generation, 1G, to the fourth generation, 4G, the development and technological advancements in telecommunications network systems have been remarkable. Faster and better connections have opened up for new markets, ideas and possibilities, to that extent that there now is a demand that surpasses the supply. Despite all these advancements made in the mobile communications field most of the concept of how the technology works and its infrastructure has remained the same. This however, is about to change with the introduction of the fifth generation (5G) mobile communication. With the introduction of 5G much of the technology introduced will be different from that of previous generations. This change extends to include the entire infrastructure of the mobile communications system. With these major changes, many of the tools available today for telecommunications network evaluation do not really suffice to include the 5G network standard. For this reason, there is a need to develop a new kind of tool that will be able to include the changes brought by this new network standard. In this thesis a simulation framework adapted for the next generation telecommunication standard 5G is set to be developed. This framework should include many of the characteristics that set 5G aside from previous generations.

Abstract:
Enhancement of QoS in PS network as 5G communication network is non trivial endeavour which faces a host of new challenges beyond 3G and 4G communication networks. The number of nodes, the homogeneity of the access technologies, the conflicting network management objectives, resource usage minimization, and the division between limited physical resources and elastic virtual resources is driving a complete change in the vision and methodologies for efficient management of the available network resources. QoS is the measure of the reliability and performance of the networks' nodes and links, particularly as perceived by the end users of the services and application that are transported via PS network. Furthermore, QoS is a composite metric as it based on a number of multiple factors, which indicate the E2E characteristics and performance of the network condition, applications and services. Hence, reductions or improvements in the QoS level can brought about through a number of combined factors. This thesis tries to introduce a vision of Quality of Service (QoS) enhancement and management based on the 5th generation network requirements and solutions by: Firstly: Proposing a traffic flow management policy, which allocates and organises Machine Type Communication (MTC) traffic flow's network resources sharing within Evolved Packet System (EPS), with an access element as a Wireless Sensor Network (WSN) gateway for providing an overlaying access channel between the Machine Type Devices (MTDs) and EPS. This proposal addresses the effect and interaction in the heterogeneity of applications, services and terminal devices and the related QoS issues among them. The introduced work in this proposal overcomes the problems of network resource starvation by preventing deterioration of network performance. The scheme is validated through simulation, which indicates the proposed traffic flow management policy outperforms the current traffic management policy. Specifically, simulation results show that the proposed model achieves an enhancement in QoS performance for the MTC traffic flows, including a decrease of 99.45% in Packet Loss Rate (PLR), a decrease of 99.89% in packet End to End (E2E) delay, a decrease of 99.21% in Packet Delay Variation (PDV). Furthermore, it retains the perceived Quality of Experience (QoE) of the real time application users within high satisfaction levels, such as the Voice over Long Term Evolution (VoLTE) service possessing a Mean Opinion Score (MOS)of 4.349 and enhancing the QoS of a video conference service within the standardised values of a 3GPP body, with a decrease of 85.28% in PLR, a decrease of 85% in packet E2E delay and a decrease of 88.5% in PDV. Secondly: Proposing an approach for allocating existing 4G installed network radio access nodes to multiple Base Band Unit (BBU) pools, which is proposed to deploy 5G Cloud-Radio Access Network (C-RAN) and improve the offered Network QoS (NQoS). The proposed approach involves performing radio access nodes clustering based on the Particle Swarm Optimization (PSO) algorithm, model selection Bayesian Information Criterion (BIC), Measure of spread technique and Voronoi tessellation. The proposed scheme is used to consider a Dynamic C-RAN (DC-RAN) operation, that adaptively adjusts the main Radio Remote Head (RRH) coverage range according to the traffic load requirement as well as considering energy saving. The numerical results of the approach show that the optimized partition of the proposed network model is 41 BBU pools, with an average density of RRHs per pool area, which matches the primary average density of the radio access nodes per network area. Thirdly: Developing mathematical framework that investigates the Power Consumption (PC) profile for the interaction of Internet of Thing (IoT) Application QoS (AQoS) with NQoS in wireless Software Defined Network (SDN) as SDN for WIreless SEnsor network (SDN-WISE). This profile model offers flexibility for managing the structure of the Machine to Machine (M2M) system in IoT. It enables controlling the provided NQoS, precisely the achieved PHY layer transmission link throughput, combined with the AQoS, represented by IoT data stream payload size. The investigation is composed of two essential SDN traffic parts, they are control plane signalling and data plane traffic PCs and their relevance with QoS. The results show that 98% PC in data plane companion with a control plane PC of 2% in overall of the proposed system power, these figures were achieved with control plane signalling Transmission Time Interval (TTI) of 5 sec and a maximum data plane payload size of 92 Bytes as a worst case scenario.

Abstract:
Dans un monde où les flux de données sont toujours plus intenses et omniprésents, les codes correcteurs d’erreurs constituent une composante essentielle aux systèmes de télécommunications, en permettant de compenser l’altération inévitable du message lors de la transmission, grâce à l’ajout de redondance. Dernière famille de codes à avoir été découverte, en 2008, les codes polaires ont rapidement attiré l’attention des chercheurs par leur aptitude à garantir une probabilité d’erreur arbitrairement faible pour tout rendement inférieur ou égal à la capacité du canal de propagation – la limite théorique, définie par Shannon en 1948. Tout récemment, ces codes ont été adoptés pour être utilisés dans la Cinquième génération de standards pour la téléphonie mobile 5G. Cette thèse porte sur l’étude de cette famille de codes face aux contraintes applicatives rencontrées en pratiques, et notamment dans la 5G, à travers les deux axes principaux que sont la construction des codes et leur décodage en longueur finie.Après avoir passé en revue la définition et la caractérisation des codes polaires, ainsi que les aspects relatifs au spectre des distances, cette thèse explore la question de la flexibilité des codes en termes de longueurs, à l’aide des techniques de poinçonnage et de raccourcissement, et développe une méthodes pour optimiser le choix des motifs de sorte à minimiser le taux d’erreur pour le décodeur par annulation successive (SC, pour successive cancellation, en anglais). Dans un deuxième temps, un nouvel algorithme de décodage à inversion est introduit, permettant une amélioration significative des performances par rapport à l’état de l’art pour une complexité moyenne réduite et proche de celle du simple décodeur SC. Finalement, la question de l’utilisation des codes polaires avec les modulations d’ordre supérieur est abordée. Tout d’abord, les deux principales approches de modulations codées utilisant un code binaire, à savoir la modulation à entrelacement de bit et la modulation multi-niveaux, sont considérées, et il est mis en évidence le net avantage de la deuxième citée. Par suite, l’utilisation de codes polaires non-binaires est envisagée et il est montré qu’au prix d’une complexité de décodage supérieure, ceux-ci sont en mesure de surpasser leurs homologues binaires
In a world of intensive and widespread numeric datafow, the use of error correcting codes has become an essential aspect of telecommunication systems, by allowing to compensate the unavoidable alteration of the messages during the transmission, by means of additionnal redundancy to the initial message. Last family of codes to be discovered, in 2008, polar codes have soon experienced a large interest of the community, due to their ability to achieve the Shannon capacity, namely the theoretical limit of the information rate, defned by Shannon in 1948. Very recently, these codes have been adopted in the fifth generation of cellular mobile communications 5G. This thesis concentrates on the analysis of this family of codes regarding constraints of practical systems, including in 5G, through the two major isues of the construction of the code and the decoding in finite length.After reviewing the definition and the caracterisation of polar codes, and addressing the question of the spectrum distance, this thesis considers the issue of the flexibility of the codes as function of the codelength, using either puncturing or shortening techniques, andd escribes a new method to select the pattern so as to minimize the error rate under succssive cancellation decoding (SC). Secondly, a new bit-fipping decoding algorithm is proposed, improving signifcantly the performance compared to state-of-the-art approach,while offering a reduced average complexity, which stays close to the one of the SC decoder. Thirdly, the issue of the use of polar codes with high order modulation is considered. On the one hand, the case of coded modulations, where a high order modulation is combined with binary codes, is considered throughthe bit-interleaved coded modulation and the multilevel coded modulation, and it is shown that the second one is very well suitable for polar codes. On the other hand, the case of non-binary codes, which can be mapped directly to the constellation, are considered and it is revealed they are able to surpass their binary counterpart at the cost of additionnal decoding complexity

The explosive growth of data traffic demands, emanating from smart mobile devices and bandwidth-consuming applications on the cellular network poses the need to drastically modify the cellular network architecture. A challenge faced by the network operators is the inability of the finite spectral resources to support the growing data traffic. The Next Generation Network (NGN) is expected to meet defined requirements such as massively connecting billions of devices with heterogeneous applications and services through enhanced mobile broadband networks, which provides higher data rates with improved network reliability and availability, lower end-to-end latency and increased energy efficiency. Device-to-Device (D2D) communication is one of the several emerging technologies that has been proposed to support NGN in meeting these aforementioned requirements. D2D communication leverages the proximity of users to provide direct communication with or without traversing the base station. Hence, the integration of D2D communication into cellular networks provides potential gains in terms of throughput, energy efficiency, network capacity and spectrum efficiency. D2D communication underlaying a cellular network provides efficient utilisation of the scarce spectral resources, however, there is an introduction of interference emanating from the reuse of cellular channels by D2D pairs. Hence, this dissertation focuses on the technical challenge with regards to interference management in underlay D2D communication. In order to tackle this challenge to be able to exploit the potentials of D2D communication, there is the need to answer some important research questions concerning the problem. Thus, the study aims to find out how cellular channels can be efficiently allocated to D2D pairs for reuse as an underlay to cellular network, and how mode selection and power control approaches influence the degree of interference caused by D2D pairs to cellular users. Also, the research study continues to determine how the quality of D2D communication can be maintained with factors such as bad channel quality or increased distance. In addressing these research questions, resource management techniques of mode selection, power control, relay selection and channel allocation are applied to minimise the interference caused by D2D pairs when reusing cellular channels to guarantee the Quality of Service (QoS) of cellular users, while optimally improving the number of permitted D2D pairs to reuse channels. The concept of Open loop power control scheme is examined in D2D communication underlaying cellular network. The performance of the fractional open loop power control components on SINR is studied. The simulation results portrayed that the conventional open loop power control method provides increased compensation for the path loss with higher D2D transmit power when compared with the fractional open loop power control method. Furthermore, the problem of channel allocation to minimise interference is modelled in two system model scenarios, consisting of cellular users coexisting with D2D pairs with or without relay assistance. The channel allocation problem is solved as an assignment problem by using a proposed heuristic channel allocation, random channel allocation, Kuhn-Munkres (KM) and Gale-Shapley (GS) algorithms. A comparative performance evaluation for the algorithms are carried out in the two system model scenarios, and the results indicated that D2D communication with relay assistance outperformed the conventional D2D communication without relay assistance. This concludes that the introduction of relay-assisted D2D communication can improve the quality of a network while utilising the available spectral resources without additional infrastructure deployment costs. The research work can be extended to apply an effective relay selection approach for a user mobility scenario.

Abstract:
Wireless communications are rapidly taking an important role in factory environment. The current Wi-Fi technologies struggle to meet the requirements of industrial factories, for example with regard to latency and security. The emerging 5G communication networks are the first networks expected to meet such requirements. Private networks are owned by the factories themselves. Private networks can utilize 5G technologies to tailor the networks to meet the exact demands within the factory environment and guarantee that the factories can use the whole bandwidth for their own use. This concurrently increases the data security as the data does not need to be deliveved over public networks. This paper describes the latest developments in 5G with regard to private networks and Industry 4.0, which is the name given to the digitalization, automatization and data exchange trend currently ongoing in factory environments. In this paper we describe a private cellular network we have installed inside a factory building. This network has been trialed with wireless pyrometer measurement data transmission and environmental surveillance of a measurement laboratory. This paper analyses the suitability of private networks for these use cases and discusses in general which applications would benefit the most from private wireless networks.
