Integrated Space/Aerial/Terrestrial 6G Networksfor Ubiquitous 3D Super-Connectivity in 2030s
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 autonomous aerial vehicles requiring connectivity, thus the 3D super-connectivity.
In this talk, we will explore a 5-layer vertical architecture (VHetNet) 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: 200-1,500 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 on opportunities and challenges.

Flexible and Cognitive Radio Access Technologies for 5G and Beyond
Prof. Huseyin Arslan (Univ. of South Florida & Istanbul Medipol Univ.)
5G aims to support new and diverse sets of application classes like eMBB communications, uRLLC and mMTC. Supporting these services using a single framework has introduced a new vision and sets of challenges for wireless researchers in many layers of the protocol stacks, especially in the Physical, Medium Access and Network Layers. The trend on the variety and the number of mobile devices along with the mobile applications will certainly continue beyond 5G. In order to create a system that can support this trend, a wide range of technical challenges and requirements must be simultanously satisfied. A robust system that ensures extreme reliability and low latency under diverse channel conditions, while minimizing production and operational costs and maximizing power and spectrum efficiency is required. Cooperative networking capability and coexistence, dynamic and flexible utilization of wireless spectrum, highly flexible, cognitive and adaptive radio access technologies are key enablers in addressing these technical challenges. In this talk, the potential directions and research opportunities to address the challenges and requirements of the 5G vision will be discussed.

Behavioral Signal Processing for Intelligent Vehicles
Pinar Boyraz Baykas, Associate Professor (Docent)
Mechanics and Maritime Sciences (M2), Division of Vehicle Safety
Chalmers University of Technology, Gothenburg, Sweden
In past two decades, we have witnessed disruptive and innovative transformations concerning how humans, machines and environment interact. These are mainly fueled by the increasing availability of real-world data (i.e. Big-Data, Naturalistic Driving Data, Medical Records), developments in Artificial Intelligence (i.e. Deep Learning) and Autonomous Cyber-Physical-Systems (i.e. Self-driving vehicles). In this seminar, we will focus on the signal processing for analyzing and modeling of human behavior in collaborative human-machine interaction scenarios.
As a special case of human-machine interaction research field, we will talk about how human drivers and intelligent vehicle technologies (i.e. partial/conditionally automated vehicles, driver assistance systems, shared control systems) interact in a collaborative manner increasing safety and efficiency. We will give detailed examples of data-driven methodologies utilizing signal processing on in-vehicle (driver-vehicle) and out-of-vehicle (vehicle-environment) data streams. This rich data stream can comprise CAN-Bus data covering vehicle dynamics, kinematics and some driver inputs (engine rpm, speed, steering wheel angle), GPS (for location), IMU (acceleration in 3-axes), in-vehicle cameras (driver’s posture, pose, head movements, facial expressions and eye-gaze), environment cameras (lane marks, traffic signs, neighboring/adjacent vehicles, lead vehicle, weather condition), LIDAR (3D obstacle map of environment).
We will explore several signal processing algorithms and their performance on this data to help the intelligent vehicle (1) understand the driver behavior (via intent recognition, fault detection, distraction detection, attention monitoring modules) for better collaboration, (2) to have context-awareness of the traffic and road conditions. Independent of the autonomy levels, all intelligent vehicle technologies should be able to recognize the driver behavior and the traffic context to be able to respond in a reliable, robust and efficient manner.

Dealing with 5G complexity with AI
5G is becoming a reality as mobile service providers are racing for initial deployments and trying to identify new use cases to create business. As opposed to previous generations, 5G is designed accomodate diverse requirements from verticals in addition to providing even faster data rates. High bandwidth applications such as 360 degree, 4K video and AR/VR, ultra delay sensitive applications in the automotive, manufacturing, healthcare, etc. industries, and massive IoT device deployments will need to be served on the same network infrastructure. 5G addresses challenges stemming from those diverse applications with a set of technological and architectural innovations such as network slicing, massive MIMO, network densification, softwarization, control and user plane separation. As the network complexity is increased tremendously, operators and vendors are investing in AI-powered network intelligence solutions for planning, operation and maintanance, resource management, performance monitoring, energy efficiency, and network optimization as opposed to traditional manual handling. To accelerate the deployment of AI-based solutions in operator networks, overlay AI network architectures on top of existing heteregenous communication infrastructure are studied by many standardization development organizations (SDO), including ITU-T focus group on “Machine learning for future networks including 5G”.
Dr. Salih Ergüt has more than 15 years of experience in the telecommunication domain in academia and industry. He has worked for vendor and operator companies in the sector including Ericsson Wireless (San Diego, CA), Ericsson Silicon Valley, Aware (Boston, MA), Nextwave (San Diego, CA), Turk Telekom Group (Istanbul, Turkey) and is currently working at Turkcell 5G R&D team in Istanbul, Turkey and serving as Vice-chairman at ITU-T Focus Group on “Machine Learning for Future Networks including 5G”.
