TUT-1, 5G Network Performance: Key Considerations & Open Challenges

Abstract: The success of 5G technology lies essentially in its ability to meet the stringent performance requirements of high-bandwidth and low latency applications. Large scale adoption of eMBB, mMTC and uRLLC use cases viz., extreme reality, industrial IoT(IIoT), haptic control and self- driven cars requires rapid deployment efforts. This tutorial discusses the key aspects affecting performance of 5G access and core networks including space, time, frequency, architectural and skill development paradigms. Firstly, the access network performance considerations in spatial, temporal and frequency domains are discussed. Approaches for modelling and analysis of 5G wireless channels and access network traffic are explored. Secondly, core network orchestration challenges are discussed with special relevance to QoS. Multi-access edge computing (MEC), network slicing, software defined networking (SDN) and network function virtualization (NFV) essential to ensure low latency are presented. Thirdly, demands for 5G training to lift the skill set of current engineers, particularly in the areas of operational technology (OT) and IIoT, covering the skills gap and availability of focussed relevant training at a professional engineers level are discussed. Some of the open challenges that need to be addressed to deliver the 5G promise are deliberated.

TUT-2, Authentication and Key Agreements in 2G, 3G, 4G, and 5G

Abstract: Authentication and Key Agreement (AKA) is a type of security protocol, used in 3GPP mobile networks, that provides two security capabilities. The first capability, called authentication, is to cryptographically assert that a mobile phone or a network is indeed who it claims to be, and the second capability, called key agreement, is to put necessary cryptographic keys in place for protection of traffic between the mobile phone and the network. Jointly, these two capabilities lay the foundation of secure 3GPP mobile networks. From 2G-5G, there are eight main versions of AKA, details of which are spread over and embedded deep in multiple technical specifications. It is getting increasingly difficult to quickly check a certain property of a certain AKA, let alone grasp the full picture of all AKAs. In this tutorial, we summarize main properties of all eight AKAs and provide pictorial “cheatsheets” which will serve as concise references. We hope these will benefit university students, security researchers, and 3GPP standardization community.

TUT-3, Homomorphic encryption over 5g networks

Abstract: A large number of user applications involving 5G data are hosted on the cloud today to cater for various business models. For example, the data captured from sensors mounted over manufacturing equipment get streamed  over 5g and processed by AI algorithms in the cloud These applications require the data to be provided during run time for processing. However, it poses security and privacy issues. One of the solutions for the secure data transfer is homomorphic encryption. It supports the consumption of the cloud APIs without the decryption of the data. However, it requires huge computation power. To reduce the same, a relevance based hierarchical homomorphic encryption would be introduced in the tutorial. It allows the creation of multiple slices to process the fragments of the data with different levels of security. For the future applications over 5G, the required large computation power for Homomorphic encryption may be provided by Quantum computers. In addition, the SDN can receive already encrypted (homomorphic) data and encrypt it further so that the contained data does not deteriorate. It is more significant for Quantum Homomorphic encryption.

Abstract: Today, the world is undergoing an unprecedented situation due to the dreadful spread of Coronavirus Disease 2019 (COVID-19), which has been announced as a pandemic by the World Health Organization (WHO) on March 11, 2020. To prevent the spread of COVID-19 severe measures have been taken by countries around the globe, including complete lockdown, social distancing, barring movements, proactive testing, restriction of social gathering, among others. Such measures have adversely affected our lifestyle, work, governance, and the overall economy. Nevertheless, we are able to pull on and have been fighting against COVID-19, thanks to the miraculous intervening of technologies. In the last couple of months, we have witnessed that technologies, if properly integrated, fine-tuned, and used appropriately, can indeed help restore and realign our world during (and post) the COVID-19 era. In this direction, the integrated role of three technologies, i.e., Blockchain, IoT, and 5G, turns out to be very promising. Thus, the tutorial will elaborate on the multifarious role of the blockchain-enabled 5G-IoT ecosystem, the key technical aspects, numerous use cases (healthcare, automated surveillance, contactless delivery, manufacturing, supply chain management), and technical challenges that need attention by the research community. The tutorial will also feature a demonstration on blockchain, which will provide an opportunity for the attendees to gain some practical exposure.

TUT-6, Voice services in 5G – Deployment options and strategies

Abstract: Voice calls or voice services are inherent to mobile networks and are a fundamental requirement. In 5G, we expect more use-cases around voice services and enhanced quality and user experience. While enterprises move to dedicated private 5G networks, they must shift to 5G voice services and leave behind legacy voice implementations. This tutorial briefly introduces 5G voice service (Voice over New Radio – VoNR) and then explains migration strategies for voice services to 5G from previous generation architectures. Next, we present deployment options for 5G voice in Non-Stand-Alone (NSA) and Stand-Alone(SA) and move to 5G voice use-cases for enterprises and how they benefit from this shift. We then review emergency voice call handling in 5G networks and evolving use-cases around voice. We will also be presenting a future architecture of voice services in 5G.

TUT-9, Achieving Global Connectivity Using Aerial and Space Networks

Abstract: The United Nations (UN) has defined a set of sustainable development goals (SDGs) targeted for 2030 that include ending poverty, hunger, and inequalities, establishing high quality of education and medical services, to name a few. Achieving such goals requires advancement in many industries, which includes the internet and communication technology (ICT) sector. In particular, establishing high quality internet service provides opportunities to stimulate economy in poor communities, access to remote learning, access to digital records and remote patient monitoring, and help farmers improve productivity. In this context, and as the standardization of the fifth generation (5G) of wireless communication systems (WCSs) has been completed, and 5G networks are in their early stage of deployment, the research visioning and planning of the sixth generation (6G) of WCSs are being initiated. However, it is well-known that urbanized regions have been the major beneficiaries of the advances in the previous generations of WCSs. Hence, it is important to carry research with the focus on ensuring digital inclusion of rural and remote areas, which currently lack stable access to internet connectivity. In this talk, we focus on (i) possible network architectures to establish backhaul connectivity in rural and remote areas, with emphasis on satellite-based solutions, (ii) current challenges facing internet access in rural areas, (iii) possible solutions to enhance internet access in rural areas, with emphasis on drone-based architectures, and (iv) existing solutions to improve the flight duration of drones and ensure stable coverage in rural areas.

TUT-10, R & D in 5G with NetSim

Abstract: Researchers lack the requisite tools for simulating end-to-end 5G networks. There are a few ‘Link-level’ simulators that enable users to model a single link between the UE and the gNB. These can’t be used for end-to-end modeling of the network, from the UE to the host-server. Even more problematically, they do not allow for modeling of the entire TCP/IP protocol stack.
This tutorial is an in-depth exploration of NetSim, an end-to-end, full-stack, packet-level simulator. We cover (i) its easy-to-use GUI with simple drag and drop functionality (ii) the results dashboard and output files for metrics such as throughput, latency, error, etc., and (iii) the 5G Protocol source C code that is provided along with, which can be modified by researchers to write their own algorithms/protocols.

TUT-12, Evolution of NOMA Toward Next Generation Multiple Access

Abstract: User data traffic, especially a large amount of video traffic and small-size internet-of-things packets, has dramatically increased in recent years. It is hence crucial to increase network capacity and user access to accommodate these bandwidth consuming applications and enhance the massive connectivity. As a prominent member of the next generation multiple access (NGMA) family, non-orthogonal multiple access (NOMA) has been recognized as a promising multiple access candidate for the sixth generation (6G) networks. The main contents of this tutorial are to discuss the so-called “One Basic Principle plus Four New” concept. Starting with the basic NOMA principle to explore the possible multiple access techniques in a non-orthogonal manner, the advantages and drawbacks of both the channel state information based successive interference cancellation (SIC) and quality-of-service based SIC are discussed. Then, the application of NOMA to meet the new 6G performance requirements, especially for massive connectivity, is explored. Furthermore, the integration of NOMA with new physical layer techniques is considered, followed by introducing new application scenarios for NOMA towards 6G. Finally, the application of machine learning in NOMA networks is investigated, ushering in the machine learning empowered NGMA era, for making multiple access intelligently for the next-generation networks.

TUT-14, 5G & Beyond: Addressing the Energy Challenge

Abstract: The advent of 5G has received a lot of hype in the news with the initial deployment of the next-generation broadband network; yet, it is quite disconcerting to realize that much of the “promise” of 5G assumes the energy infrastructure exists to power all these new capabilities. Even more challenging: many use cases assume that the network can be fully utilized, while neglecting bottlenecks that depend on energy constraints rather than data throughput; thus, the payback estimates underpinning these massive investments may be substantially flawed.
The “5G Energy Gap” is a risk to the entire deployment and the benefits that can be derived. New methods for analyzing the system’s constraints and bottlenecks are presented through the concepts of the Power Value Chain, Power Cost Factor, 5G Derate Factor, and other technical/business and even socioeconomic factors.
This entry/intermediate-level tutorial introduces these concepts in a simple, yet realistic way and provides insight on how to address the complexity of the network so that all stakeholders can gain visibility on its energy footprint and translate the unique inputs/requirements of each part into the normalized, “universal currency” of energy. This approach allows performing static and dynamic analyses to achieve energy efficient optimization, and thus technical and business viability.

TUT-15, Evolution of Direct RF Sampling Technology – Recent Advances, Challenges, and the Road Ahead

Abstract: Traditional radio receivers including the latest cellular devices typically contain radio frequency (RF) front-ends employing super heterodyning that essentially dissociate the analog domain RF signal processing from the baseband signal processing pursued in the digital domain. The intermediate frequency (IF) based analog implementation of super heterodyne RF front-ends has ruled the radio world for almost three decades. But the recent advances in CMOS technology are gradually pushing a paradigm shift, with majority of RF signal processing moving into the digital domain. Direct RF sampling at receiver and its counterpart direct RF synthesis at transmitter bring a host of advantages and benefits in terms of radio design, but they also encounter a multitude of challenges. In this tutorial, we are going to study the pros and cons of various RF front-end architectures, including the direct conversion, super heterodyne with analog IF, super heterodyne with digital IF, and direct RF sampling/synthesis based alternatives. We are going to examine at least two case studies to further explain the design intricacies in RF front-end design. The second part of the tutorial will focus on the challenges specific to direct RF sampling and direct RF synthesis architecture. We will consider examples of practical transceivers built around direct RF sampling technology, and explain how they address those challenges. Finally, we will learn about the road ahead and will try to predict together the future of direct RF sampling technology.
