Title: Wireless Infrastructure of the Future: Integrated Terrestrial-HAPS-LEO Networks 

 Abstract:

In this tutorial, we will present a multi-layer vertical access architecture composed of fully integrated terrestrial and non-terrestrial layers towards a vertical HetNet which is expected to evolve progressively in the next 20 years, during the 6G era and beyond. In particular, we will examine a new access & computing layer composed of HAPS (high altitude platform station) systems in stratosphere, 20 km above the ground, in addition to the legacy terrestrial layer and the emerging satellite layer.  With its bird’s-eye and almost-line-of-sight view of an entire metropolitan area, a HAPS is more than a base station in the air; it is a new architecture paradigm with access, transport, and core network functionalities for integrated connectivity, computing, sensing, positioning, navigation, and surveillance, towards enabling a variety of use-cases in an agile, smart, and sustainable manner for smart cities and societies of the future. The tutorial will feature a number of enabling technologies for the envisioned architecture including RIS (reconfigurable intelligent surfaces) and advanced antennas.

Title: “Deep Learning Aided Intelligent Sensing and Identification for Secure Wireless Communications“

Abstract:

With the rapid development in artificial intelligence (AI) and deep learning (DL), it can be foreseen that the future wireless communication systems will have much more intelligence and secure than the predecessors. For problems that can be accurately modeled, traditional algorithms show good performance and efficient solutions on partially convex problems. However, for some non-convex problems, existing algorithms usually obtain more efficient solutions while allowing a certain performance loss. At this time, the DL technology is used to mine the parameter information of the known structure algorithm from the obtained data samples, to improve the convergence speed of the algorithm and the performance of the algorithm. In this talk, the artificial neural networks (ANNs) including deep neural network (DNN), convolutional neural network (CNN) and so on are used to parameterize the model or algorithm, and the gradient based methods are used to optimize the NNs. These methods that obtain model or algorithm features from massive amounts of data rather than based on pre-established rules are generally called data-driven. Here, this talk focuses on the research and application of DL in physical layer. On the one hand, model based algorithms for signal detection or channel estimation can be enhanced by DL to improve the computing efficiency and system performance. On the other hand, traditional model-based methods are increasingly unable to meet the increasing demands of next-generation communication systems under the channel conditions with more complex interference and higher uncertainty. DL has the potential opportunities to redesign the baseband module including coding/decoding, detection and so on.

Prof. Byonghyo Shim (Seoul National Univ.)
Title: Computer Vision (CV)-aided Wireless Communication for 6G

Abstract:
Recently, we are now witnessing the emergence of unprecedented services and applications using artificial intelligence (AI) such as the autonomous vehicles, drone-based deliveries, smart cities and factories, remote medical diagnosis and surgery, to name just a few. AI-based approaches are data-driven in nature, so applications using visual and audio/speech data are popular among others. In particular, computer vision (CV) technique, a field of AI that enables computers to derive meaningful information from visual data such as image and video, has achieved a remarkable success in various tasks such as the image classification, object detection, image captioning, and saliency detection. In the perspective of future wireless systems, benefits of CV are twofold: First, physical characteristics of wireless signals (in particular, mmWave and THz radio waves) are very close to the sensing signal (e.g., visible light in 400∼790 THz) in that the transmit energy is mostly concentrated in the line of sight (LoS) path. Second, recent advances of the CV techniques have made a gigantic improvement in various tasks, from which we can infer that the CV techniques can dramatically reduce the complicated control process of the wireless communication systems since the essential operation of CV-aided wireless systems is to capture the image and use AI in performing the desired task. In this tutorial, we present CV-aided future wireless systems equipped with the visual sensing mechanism (e.g., RGB, LiDAR, laser, infrared). After discussing basics of sensing devices and deep learning (DL) mechanism, we will explain the state-of-the-art CV-techniques and its applications to 6G wireless communication systems. We will also discuss the practical issues such as multi-modal sensor fusion, dataset acquisition, model training, and integration with communication systems. From our discussion, we will show that the CV technique is effective in improving the reliability and capacity, reducing the end-to-end latency and power consumption, and also operation cost of wireless systems.

Tutorial 4

Prof. Yi Hong (Monash Univ.)
Title: OTFS and delay-Doppler Communications 

Abstract:

Orthogonal time frequency space (OTFS) modulation has been recently proposed by Hadani et al. at WCNC’17, San Francisco. It was shown to offer significant advantages over OFDM in doubly dispersive channels for high mobility wireless communications. The key idea of OTFS is to model mobile wireless channels in the delay-Doppler domain, where a sparse nature of the geometry of the wireless channel is captured. This tutorial will introduce the general notion of OTFS/delay-Doppler communications, starting from the fundamentals of high mobility wireless channels, followed by the transceiver architecture used for detection and channel estimation and finally the potential application to LEO Satcom.
