Abstract: Software defined wireless networking (SDWN) is an emerging communications paradigm and an essential technology in the next-generation 5G systems. In SDWN, software oriented design, the separation of the data and control planes, and network virtualization, can unfold numerous advantages to manage network complexity and dynamics. In the tutorial, we will introduce the key concepts related to Software Defined Networks (SDN) and SDWN. Then, we will mainly focus on exploring software designed principle in various wireless networks, including software defined device-to-device communications, software defined sensor networks, software defined wireless mesh networks, and software defined vehicular networks.

Abstract: Massive MIMO is the currently most compelling sub-6 GHz wireless access technology for 5G. The key concept is to equip base stations with arrays of many antennas, which are used to serve many terminals simultaneously, in the same time-frequency resource. Massive MIMO provides uniformly good service to wireless terminals in high-mobility environments. Since its inception about a decade ago, it has evolved from a wild academic idea to one of the primary research topics in the wireless communications community, as well as a main work item in 5G standardization. This tutorial will cover the fundamental theory behind this technology, much based on the recent Cambridge text Fundamentals of Massive MIMO, along with some more recent results.

Abstract: A key trend in networking during the past decade is to push various capabilities, such as computation, control, and storage, to the cloud. Such a cloud-centric architecture is not suitable for satisfying the demands of many delay-sensitive applications in 5G and IoT. An emerging alternative paradigm is the fog computing, where the cloud descends to the network edge and diffuses among the client devices in both mobile and wireline networks. This tutorial will provide an overview and discuss the technical and economic challenges of fog computing and networking, both in terms of industry practice and academic research.

Abstract: In recent years, we have seen an explosion of location-based services. These services rely on an accuracy performance that was “envisioned” two decades ago, when the FCC demanded from the network operators to determine the whereabouts of 911 callers within a certain range. Now, upcoming 5G services demand high reliability and very precise accuracy in the cm-range. In this tutorial, we will present the fundamentals of cellular localization, location-awareness in cellular communication systems, the evolution of cellular localization standards from 1G to 4G, and the new localization trends from 4G towards 5G, in order to fulfill future applications.

Abstract: Multiple access in 5G mobile networks is an emerging research topic, since it is key for the next generation network to keep pace with the exponential growth of mobile data and multimedia traffic. Non-orthogonal multiple access (NOMA) has recently received considerable attention as a promising candidate for 5G multiple access. Recent demonstrations by industry show that the use of NOMA can significantly improve the spectral efficiency of mobile networks. In this tutorial, we will provide a progress review for NOMA, including the design of multi-input multi-output (MIMO) and cooperative NOMA, the application of NOMA in millimeter-wave (mmWave) networks, hybrid NOMA, resource allocation for NOMA, and the impact of practical constraints on the performance of NOMA.

This tutorial will shed light on the challenges, solutions and technologies focusing on open-source tools, allowing to build a flexible and programmable mobile network. Particularly, the tutorial will rely on concrete solutions, developed by the speakers using OpenAirInterface and Mosaic-5G platform, to demonstrate a realization of network slicing concept.

TS10. Resource Allocation in Wireless Networks under Uncertainties: A Stochastic Optimization FrameworkRoom: 233M
- Allen B. MacKenzie, Virginia Tech, USA
- Mohammad J. Abdel-Rahman, Virginia Tech, USA
Abstract: Emerging wireless networks operate using dynamic and uncertain resources that render them susceptible to severe performance degradation. Managing stochastic resources in such networks while ensuring a certain level of network performance is challenging. In this tutorial, we introduce stochastic optimization as a powerful tool to handle resource allocation in uncertain networks, discuss various approaches to modeling uncertainty, and explain different feasibility and optimality approaches under uncertainty. Throughout the tutorial, we will illustrate how to use various stochastic optimization approaches to formulate example resource allocation problems in (i) LTE, (ii) WiFi, (iii) millimeter wave, (iv) virtualized, and (v) software-defined wireless networks.

Abstract: The fundamental bottleneck towards enormous spectral efficiencies in MIMO networks lies in huge demands for accurate channel state information at the transmitter (CSIT), essential for multiuser interference management. Traditional approaches strive to apply techniques designed for perfect CSIT to scenarios with imperfect CSIT. We depart from this tradition and introduce the audience to rate splitting (RS), where common messages decoded by multiple users are transmitted alongside conventional private messages decoded by their corresponding users. RS provides significant benefits in terms of spectral efficiencies, reliability and CSI feedback overhead reduction over conventional strategies in a wide range of applications and scenarios.

Abstract: This tutorial covers both theoretical and implementation aspects of on-line machine learning for dynamic spectrum access in order to solve spectrum scarcity issue. We show that most dynamic solution, e.g. Opportunistic Spectrum Access (OSA), can be modelled as a multi-armed bandit (MAB) problem. We then derive mathematical solutions: (i) frequentist solutions, such as UCB and KL-UCB; (ii) Bayesian solutions, such as Bayes UCB and Thompson Sampling. A demonstrator running reinforcement learning algorithms on real radio signals confirms the mathematical derivations in several contexts of both i.i.d. and Markovian spectrum load, with mono and multi-users scenarii for OSA.

Abstract: The tutorial highlights the most prominent networking challenges for millimeter-wave (mm-wave) communications. Mm-waves communications are characterized by the high signal attenuation, which can only be overcome by highly directional antennas. The reduced interference compared to communication at lower frequencies, allows for a high degree of spatial reuse and potentially simpler Medium Access Control Protocols (MAC). But high directionality may cause deafness due to beam misalignments, and sudden communication blockages due to obstacles. We give an overview of mm-wave communication characteristics, and on the most important network and protocol design aspects, from beam-training and MAC to efficient network architectures.

Abstract: In this tutorial, we will present several aspects that make 5G ultra-dense networks (UDNs) fundamentally different from 3G/4G sparse/dense ones: 1) the higher probability of line-of-sight (LoS) transmissions between base stations (BSs) and user equipment (UEs); 2) the non-negligible antenna height difference between BSs and UEs; 3) the surplus of BSs with respect to UEs; 4) the proportional fair scheduler in BSs; and 5) the busty traffic demands in the downlink and uplink. Thereafter, we will discuss the need of unlicensed spectrum for cost-effectively enhancing capacity in the sub-6GHz band. Special attention will be paid to LWA, LWIP and LAA.

Abstract: The invention of polar codes by Arikan has introduced a new coding paradigm in channel coding. As opposed to turbo codes and LDPC codes under iterative decoding, polar codes under successive cancellation (list) decoding follow very different principles for analysis, design and decoding. Originally only investigated in academia, polar codes have now also become a hot topic in industrial research with their recent adoption in the 5G standard. This tutorial provides a brief revision of the principles of polar coding, addresses in detail the challenges of design and decoding related to practically important finite lengths, and will give an insight into the 5G standardisation process.
