TUT-1: Wireless Networks Design: Model-Based or Data-Driven?
Room: RENO

Recently, deep learning has received signiﬁcant attention as a technique to design and optimize wireless communication systems and networks. The usual approach to use deep learning consists of acquiring large amount of empirical data about the system behavior and employ it for performance optimization (data-driven approach). We believe, however, that the application of deep learning to communication networks design and optimization offers more possibilities. As opposed to other ﬁelds of science, such as image classiﬁcation and speech recognition, mathematical models for communication networks optimization are very often available, even though they may be simpliﬁed and inaccurate. We believe that this a priori expert knowledge, which has been acquired over decades of intense research, cannot be dismissed and ignored. In this tutorial, in particular, we put forth a new approach that capitalizes on the availability of (possibly simpliﬁed or inaccurate) theoretical models, in order to reduce the amount of empirical data to use and the complexity of training artiﬁcial neural networks (ANNs). We concretely show, with the aid of some examples, that synergistically combining prior expert knowledge based on analytical models and data-driven methods constitutes a suitable approach towards the design and optimization of communication systems and networks with the aid of deep learning based on ANNs.

The tutorial is structured in three main parts:

Data-driven design of wireless networks
Model-based design of wireless networks
Embedding expert knowledge into deep learning

and will be based on the following recent publications of the authors:

TUT-2: Connected Vehicles in the 5G Landscape
Room: LAUGHLIN1

The road is being paved right now to enact the vision of connected cars, leveraging efforts that have been going on since the beginning of this century, especially within IEEE and ETSI. Now, the upcoming 5G technology is expected to be a game changer for vehicular communication, with the automotive sector having already secured its place among the most prominent verticals. The possibility for vehicles to be connected to other vehicles, pedestrians, roadside infrastructure or application servers, enables the development of safety services as well as multiple revolutionary applications such as fully automated or remote driving. Additional use cases embrace the wider area of Intelligent Transportation Systems (ITS). The traditional approach through Dedicated Short Range Communication (IEEE 802.11p/DSRC) is being challenged by new paradigms that are often referred to as Cellular Vehicle-to-Everything (C-V2X), a technology concept that features prominent roles for cellular standards in a wide range of vehicle connectivity use cases and applications. A viable C-V2X technology implementation is available since 3GPP Release 14, shoehorning C-V2X support in 5G networks. This Tutorial will cover both the state-of-the-art of vehicular communication and networking, from the point of view of protocols and regulations, as well as the most recent proposals in the context of C-V2X along with the requirements for the novel use cases they are ushering, some of them taken from ongoing research projects. Overall, the Tutorial will provide a comprehensive view of how inter-vehicular communication will fit into the broader 5G landscape.

Room: LAUGHLIN1

TUT-4: LTE-NR Dual Connectivity as the First Step to Commercial 5G
Room: LAUGHLIN2

New Radio (NR) technology aims to satisfy both urgent market needs - by assisting LTE radio - and the longer-term requirements of the 5th Generation on (5G). In this context, Non-standalone (NSA) NR - by means of LTE-NR Dual Connectivity (DC) - is one of the primary technology components of 5G. The concept of NSA NR is identified by 3GPP as one of the most important technology components of 5G where NR, with its future-proof functionalities, can co-exist with LTE radio to improve network performance. Initially, this co-existence is enabled with a limited set of NR features by exploiting the existing LTE Radio Access Network (RAN) and Core Network (CN) - EPC - infrastructure. However, when the full set of standalone NR features will be developed, the dual connectivity between LTE and NR will comprehend more architecture options enabled by a new 5G CN (5GC). The introduction of NSA NR will make the key benefits of 5G technologies available to users much earlier than expected (i.e., Q4 2018/Q1 2019) since it will allow mobile operators to leverage their existing LTE deployments with on-demand NR aggregation. In this tutorial, we will explain the LTE-NR DC concepts and describe the key features that have been specified by the 3rd Generation Partnership Project (3GPP) during Release 15. Furthermore, we will analyze the NSA performance with respect to LTE and standalone NR and show 5G trial case stories that are happening all over the world. Finally, we will discuss the new concepts and upcoming features foreseen for the NR standardization such as Multi-RAT Dual Connectivity (MR-DC) cases with the 5G core network, 5GC.

TUT-5: Ultra-Reliable and Low-Latency Communications Services in 5G
Room: LAUGHLIN2

In this tutorial, we will discuss the key challenges and feasible approaches in supporting ultra-reliable and low-latency communication (URLLC) services in 5G. We first give an overview of various deployment scenarios in 5G. The challenges of 5G URLLC services lie in the fact that transmission losses, handoff delays, and re-routing delays have more severe impact when the link data rate increases. We will focus on dynamic resource allocation and intelligent interference management techniques to enhance reliability, system throughput and sustain low latency transmission. Last, potential research issues in radio access technologies for supporting URLLC services in 5G networks will be highlighted.

TUT-7: Integrated Aerial/Terrestrial 6G Networks for Ubiquitous 3D Super-Connectivity
Room: LAUGHLIN1

The 5G standards are currently being developed with a scheduled completion date of late-2019; the 5G wireless networks are expected to be deployed globally throughout 2020s. As such, it is time to reinitiate a brainstorming endeavour followed by the technical groundwork towards the subsequent generation (6G) wireless networks of 2030s.

One reasonable starting point in this new 6G discussion is to reflect on the possible shortcomings of the 5G networks to-be-deployed. 5G promises to provide connectivity for a broad range of use-cases in a variety of vertical industries; after all, this rich set of scenarios is indeed what distinguishes 5G from the previous four generations. Many of the envisioned 5G use-cases require challenging target values for one or more of the key QoS elements, such as high rate, high reliability, low latency, and high energy efficiency; we refer to the presence of such demanding links as the super-connectivity.

However, the very fundamental principles of digital and wireless communications reveal that the provision of ubiquitous super-connectivity in the global scale – i.e., beyond indoors, dense downtown or campus-type areas – is infeasible with the legacy terrestrial network architecture as this would require prohibitively expensive gross over-provisioning. The problem will only exacerbate with even more demanding 6G use-cases such as UAVs requiring connectivity (ex: delivery drones), thus the 3D super-connectivity.

In this talk, we will present a 5-layer vertical architecture composed of fully integrated terrestrial and non-terrestrial layers for 6G networks of 2030s:

Terrestrial HetNets with macro-, micro-, and pico-BSs
Flying-BSs (aerial-/UAV-/drone-BSs); altitude: up to several 100 m
High Altitude Platforms (HAPs) (floating-BSs); altitude: 20 km
Very Low Earth Orbit (VLEO) satellites; altitude: up to 1,000 km
Geostationary Orbit (GEO) satellites; altitude: 35,786 km

In the absence of a clear technology roadmap for the 2030s, the talk has, to a certain extent, an exploratory view point to stimulate further thinking and creativity. We are certainly at the dawn of a new era in wireless research and innovation; the next twenty years will be very interesting.

No specialized knowledge is expected from the audience. Researchers, engineers, and policy makers from government, industry, and academia (including graduate students and 4th year undergraduate students) will benefit from this visionary tutorial.

TUT-8: Coding Theory Based Cryptography for the Internet-of-Things
Room: LAUGHLIN2

An increasingly important aspect of any communications system, especially for such critical tasks as network data collection, is ensuring different dimensions of security by means of the confidentiality, integrity, and availability. While there is a good, rich, and robust literature of cryptographic methods, the need to improve the security in response to ever-increasing sophistication levels of the attackers, coupled with the serious, potential threat from quantum computing opens up new challenges. Rapid proliferation of resource-constrained devices, also known as Internet-of-Things (IoT), in conjunction with the increased needs for device-to-device (D2D) communications, brings a new constraint to the security realm in terms of a need for a low-level computational overhead while not compromising the security expectations. Finding a good operational point in the security-performance trade off exacerbates the already challenging problem. One promising technique of providing a high-level of security with improved performance is from the field of code-based cryptography. Unlike the traditional public-key cryptography, which is based on the intractability of integer factorization and discrete logarithm problems which are not secure against quantum algorithms, code-based cryptography makes use of the hardness of the decoding problem from the error correcting codes, for which there is no known, efficient quantum algorithm. In this tutorial, we will present coding theory-based cryptography as a promising solution for the cyber security paradigm and infrastructure of the future with quantum computing resistance and good computational overhead especially for the emerging IoT devices in the consumer communications domain with lax security mechanisms.
