WS-4: Workshop on Integrating UAVs into 5G and Beyond

General Co-chairs:

  • Prof. Qingqing Wu, University of Macau, China
  • Prof. Jie Xu, The Chinese University of Hong Kong, Shenzhen, China
  • Prof. Giovanni Geraci, Universitat Pompeu Fabra, Spain
  • Prof. Yong Zeng, Southeast University, China
  • Dr. Adrian Garcia-Rodriguez, Huawei R&D, France

Scope:

Unmanned aerial vehicles (UAVs) have found fast growing applications during the past few years. As such, it is imperative to develop innovative communication technologies for supporting reliable UAV command and control (C&C), as well as mission-related payload communication. However, traditional UAV systems mainly rely on the simple direct communication between the UAV and the ground pilot over unlicensed spectrum (e.g., ISM 2.4GHz), which is typically of low data rate, unreliable, insecure, vulnerable to interference, difficult to legitimately monitor and manage, and can only operate within the visual line of sight (LoS) range. To overcome the above limitations, there has been significant interest in integrating UAVs into cellular communication systems. On the one hand, UAVs with their own missions could be connected into cellular networks as new aerial users. Thanks to the advanced cellular technologies and almost ubiquitous accessibility of cellular networks, cellular-connected UAVs are expected to achieve orders-of-magnitude performance improvement over the existing point-to-point UAV communications. It also offers an effective option to strengthen the legitimate UAV monitoring and management, and achieve more robust UAV navigation by utilizing cellular signals as a complement to GPS (Global Position System). On the other hand, dedicated UAVs could be deployed as aerial base stations (BSs), access points (APs), or relays, to assist terrestrial wireless communications from the sky, leading to another paradigm known as UAV-assisted communications. UAV-assisted communications have several promising advantages, such as the ability to facilitate on-demand deployment, high flexibility in network reconfiguration, high chance of having LoS communication links, and enable numerous applications such as BS traffic offloading, information dissemination and collection for Internet of Things (IoTs).

UAV communications are significantly different from conventional communication systems, due to the high altitude and high mobility of UAVs, the unique channel of UAV-ground links, the asymmetric quality of service (QoS) requirements for downlink C&C and uplink mission-related data transmission, the stringent constraints imposed by the size, weight, and power (SWaP) limitations of UAVs, as well as the additional design degrees of freedom enabled by joint UAV mobility control and communication resource allocation.

Considering the great success of the previous workshops at ICC 2018, ICC 2019, ICC 2020, and ICC 2021, we aim to organize the 5th Workshop on “Integrating UAVs into 5G and Beyond” at ICC 2022 to bring together academic researchers, industrial practitioners, and individuals working on this emerging exciting research areas to share their new ideas, latest findings, and state-of-the-art results.

WS-5: Workshop on OTFS and Delay-Doppler Signal Processing for 6G and Future High-Mobility Communications

General Co-chairs:

  • Jinhong Yuan, University of New South Wales, Australia
  • Jingxian Wu, University of Arkansas, US
  • Yi Hong, Monash University, Australia
  • Hai Lin, Osaka Prefecture University, Japan

TPC Co-chairs:

  • Giulio Colavolpe (Lead), University of Parma, Italy
  • Ananthanarayanan Chockalingam, Indian Institute of Science, India
  • Baoming Bai, Xidian University, China
  • Weijie Yuan, Southern Univ. of Science and Technology, China
  • Zhiqiang Wei, Friedrich-Alexander University Erlangen-Nuremberg, Germany

Scope:

Communications in high mobility scenarios suffer from severe Doppler spreads, which deteriorate the performance of the widely adopted orthogonal frequency division multiplexing (OFDM) modulation in the current 4G and 5G networks. Recently, a new two-dimensional modulation scheme referred to as orthogonal time frequency space (OTFS) was proposed, where the information symbols are multiplexed in the Delay-Doppler (DD) domain. OTFS provides the possibility to embrace localized delay and Doppler impairments and converts time-frequency selective channels in to an invariant channel in the DD domain. More importantly, OTFS enjoys the full time-frequency diversity of the channel, which is the key to provide reliable transmissions for the future 6G and high mobility communications. This workshop aims at bringing together academic and industrial researchers in an effort to identify and discuss the major technical challenges, recent breakthroughs, and new applications related to OTFS.

WS-6: Workshop on Rate-Splitting Multiple Access for 6G

General Co-chairs:

  • Wonjae Shin, Ajou University, South Korea
  • Yijie (Lina) Mao, ShanghaiTech University, China
  • Seok-Hwan Park, Jeonbuk National University, South Korea

Guest Speaker:

  • Aydin Sezgin, Ruhr-University Bochum, Germany

Scope:

To efficiently cope with the high throughput, reliability, heterogeneity of Quality-of-Service (QoS), and massive connectivity requirements of future multi-antenna wireless networks, multiple access and multiuser communication system design need to depart from two conventional and extreme interference management strategies, namely fully treat interference as noise (as commonly used in 4G, MU-MIMO, CoMP, Massive MIMO, millimeter wave MIMO) and fully decode interference (as in Non-Orthogonal Multiple Access - NOMA).

This workshop is dedicated to the theory and applications of a more general and powerful transmission framework based on Rate-Splitting (RS) that consists in decoding part of the interference and in treating the remaining part of the interference as noise. This enables RS to softly bridge and therefore reconcile the two extreme strategies of fully decode interference and treat interference as noise and provide room for spectral efficiency, energy efficiency and QoS enhancements in a wide range of network loads and user deployments, robustness against imperfect Channel State Information at the Transmitter (CSIT), as well as feedback overhead and complexity reduction.

Keynote Speakers:

  • Yonina C. Eldar, Weizmann Institute of Science, Israel
  • Christos Masouros, University College London, UK
  • Tony Xiao Han, Huawei Technologies Co. Ltd., China

Scope:

As the standardization of 5G is gradually being solidified, researchers are speculating what 6G will be. A common theme in many perspectives is that 6G Radio Access Network (RAN) should serve as edge infrastructure to provide site-specific services for surrounding users, rather than communication-only functionality. Jointly suggested by recent advances from the signal processing society and the communications society, radio sensing functionality can be integrated into 6G RAN in a low-cost and fast manner. Therefore, the future cellular network could image and measure the surrounding environment to enable advanced location-aware services, ranging from the physical layer to application layers. This type of research is typically referred to as Integrated Sensing And Communication (ISAC).

In essence, ISAC can acquire two main advantages over dedicated sensing and communication functionalities: 1) Integration gain to efficiently utilize congested resources for dual use of both communications and sensing, and even more interesting, 2) Coordination gain to balance dual-functional performance or/and perform mutual assistance. Benefiting from these two advantages, applications of ISAC have been extended to numerous emerging areas, including vehicular networks, environmental monitoring, Internet of Things, as well as in-door services such as human activity recognition.

WS-8: Workshop on Synergies of Communication, Localization, and Sensing towards 6G

General Co-chairs:

  • Henk Wymeersch, Chalmers University of Technology, Sweden
  • Stefania Bartoletti, CNR and CNIT, Italy
  • Liesbet Van der Perre, KU Leuven, Belgium
  • Angeliki Alexiou, University of Piraeus, Greece
  • George C. Alexandropoulos, National and Kapodistrian University of Athens, Greece

Scope:

Research on 6G is now well underway and several large initiatives have been launched around the globe to define what this new generation of wireless networks will be. These definitions are supported by a wide variety of technological enablers, ranging from access in the THz spectrum, which brings massive bandwidths and laser-like beamforming capabilities, to the introduction of new antenna technologies and intelligent metasurfaces, which provide massive apertures and new ways of shaping the propagation medium. Due to the wide variety of envisioned use cases, 6G will not lead to a one-size-fits-all solution, but rather inspire a rich diversity in terms of devices, spectrum usage, and technologies. Common among many emerging services in need of 6G is the requirement for localization and sensing to be an integral part of 6G. The ability of 6G to locate and track active users as well as passive objects will be part of the core communications functionality and will enable and enrich a wide variety of futuristic services, including immersive augmented reality, robot collaboration, and environment/earth monitoring. These services will lead to a more inclusive and sustainable 6G ecosystem. The overarching vision of this workshop is that the synergies among localization, sensing, and communications within the 6G ecosystem require a common venue, not focusing on any specific technological enabler, but rather support a broad and diverse set of viewpoints, including those from industry (telecom and radar industries) and academia (communications, signal processing, and circuits communities).

TPC Co-chairs:

  • Prof. Alan E. Willner, USC, USA
  • Prof. Boon S. Ooi, KAUST, Saudi Arabia
  • Prof. Shilie ZHENG, Zhejiang University, China

Scope:

Orbital Angular Momentum (OAM) is regarded as one of the potential key technologies for B5G and 6G mobile communications, which can provide additional multiplexing and higher spectrum efficiency. For example, Tbps data rate is aimed with OAM channels multiplexed in the free space point-to-point backhaul transmission. In addition, the fundamental theoretical study of OAM has already been engaged in the quantum mechanics for a long time. Many researchers in the vortex electron show the promising technology in OAM photon radiation and reception, e.g., relativistic electron cyclotron radiation and electron cyclotron masers. Therefore, the 4th workshop on OAM transmission in ICC2022 will focus on both the detailed physical theories of OAM and applications in wireless communications. The workshop is expected to be held with the discussion of the state-of-the-art research on OAM transmission and the promising future applications.

Scope:

Blockchain, as a distributed ledger technology, has drawn tremendous attention in various applications and fields in the past few years. The evolution of blockchain technologies has experienced a series of challenges including malicious behaviors occurred in blockchains, low throughput, and poor scalability, and etc. Various theories, frameworks, consensus models, and sophisticated mechanisms have been proposed to deal with the above problems of the blockchain but all suffer from limited performance. The recent advances in Artificial Intelligence (AI), however, have brought new opportunities in overcoming the challenges of blockchains, spawning a new direction named Intelligent Blockchain. However, aiming towards more scalable, secure, and intelligent blockchains, there is still a long way to go.

As we believe, the future networking and communications will closely fuse with the development of the 5th Generation (5G) and Beyond-5G technologies. Meanwhile, a series of technical issues are emerging in the era of future networking and communications, such as the privacy and security of user data, the supervision of malicious behaviors, the audition of user identities, resource allocation. Once the blockchain technology becomes more scalable, secure and intelligent in the near future, it will spark more blue-sky thinking, and innovative ideas that can improve the future networking and communications to another level with strong performance guarantee.

WS-11: Workshop on Semantic Communications

General Co-chairs:

  • Wen Tong, Huawei, Canada
  • Geoffrey Ye Li, Imperial College London, UK
  • Tolga M. Duman, Bilkent University, Turkey
  • Zhijin Qin, Queen Mary University of London, UK
  • Rong Li, Huawei China

Scope:

In contrast to the Shannon paradigm whose underlying principle is to guarantee the correct reception of each single transmitted packet regardless of its meaning, the semantic communication is concerned with the problem of how transmitted symbols convey a desired meaning to the destination, as well as how effectively the received meaning affects the action in a desired way. By communicating the meaning or semantics of the data, semantic communication holds the promise of making wireless networks significantly more energy- efficient, robust, and sustainable.

Moreover, the advancements on artificial intelligence (AI) provide a powerful tool for solving the fundamental problems in semantic communications, such as lack of mathematical model for semantic information. As a result, significant efforts have been made recently to design the machine learning (ML)-based semantic communications for future wireless networks. To build a pathway to semantic communications, network architecture, information processing, and transmission technologies, including physical (PHY) layer processing, medium access control (MAC), and air-interface in general should be redesigned carefully.

WS-12: Workshop on Industrial Private 5G-and-beyond Wireless Networks

General Co-chairs:

  • Kyeong Jin Kim, Mitsubishi Electric Res. Labs, USA
  • David López-Pérez, Huawei Tech., France
  • H. Vincent Poor, Princeton Univ., USA
  • Miaowen Wen, South China Univ. of Tech., China
  • Petar Popovski, Aalborg Univ.,Denmark
  • Theodoros A. Tsiftsis, Jinan Univ., China

Scope:

The fifth generation (5G) of radio technology will deliver multi-Gbps peak data rates, ultra-reliable low latency, and massive connectivity, thus having a large number of new applications and opening a wide variety of business opportunities. For example, 5G has the potential to shape the industrial world, through the automation of everything. However, public 5G networks, which are owned and operated by mobile network operators, are not suited for the demanding industrial use cases. For instance, on their pursuit of revenue, mobile network operators may deploy networks only in well-populated areas with plenty of subscribers. This may result in limited public network coverage, particularly in some enterprise and remote areas, far away from business hubs. Public network coverage may also often be insufficient within some industrial buildings and factories, with harsh radio frequency operating conditions. Unplanned inter-cell interference may also comprise necessary reliability and latency targets. Therefore, industrial private networks have emerged and are attracting a significant interest to address the above-mentioned defects. This workshop aims to bring researchers for technical discussion on fundamental and practically relevant questions to many emerging challenges in industrial private wireless networks.

WS-13: Workshop on Edge Learning for 5G Mobile Networks and Beyond

 Steering Committee:

  • Shuguang Cui, The Chinese University of Hong Kong, Shenzhen
  • Kai-Kit Wong, University College London
  • H. Vincent Poor, Princeton University

General Co-chairs:

  • Mingzhe Chen, Princeton University
  • Osvaldo Simeone, King’s College London
  • Zhaohui Yang, University College London

Keynote Speakers:

  • Deniz Gunduz Imperial College London
  • Salman Avestimehr University of Southern California 

Scope:

Nowadays, standard machine learning approaches require centralizing the training data on a single data center or cloud. Since massive data samples need to be uploaded to the data center, transmission delay can be very high and user privacy is not guaranteed in standard centralized machine learning approaches. However, low-latency and privacy requirements are important in the emerging application scenarios, such as unmanned aerial vehicles, extended reality services, autonomous driving, which makes centralized machine learning approaches  inapplicable.

Moreover, due to limited communication resources, it is impractical for all the wireless devices that are engaged in learning to transmit all of their collected data to a data center that uses a centralized learning algorithm for data analytic or network self-organization. Therefore, it becomes increasingly attractive to deploy learning algorithms at edge devices, called edge learning. A typical edge learning framework (e.g., federated learning) features distributed learning over many wireless end-user devices cooperating with edge devices, such as access points or base stations, to train a common AI model using distributed local data. This scenario typically involves an iterative learning process, repeatedly downloading and uploading possibly high-dimensional (millions to billions) model parameters or their updates by tens to hundreds of edge devices. This may generate substantial data traffic, placing a heavy burden on already congested radio access networks. The training problem cannot be efficiently solved using traditional wireless techniques targeting at rate maximization while decoupled from learning.

WS-14: Workshop on Terahertz Communications

General Co-chairs:

  • Josep M. Jornet, Northeastern University, USA
  • Ho-Jin Song, Pohang University of Science and Technology, Republic of Korea
  • Zhi Chen, University of Electronic Science and Technology of China

TPC Co-chairs:

  • Hina Tabassum, York University, Canada
  • Gianni Pasolini, University of Bologna, Italy
  • Sergi Abadal, Universitat Politecnica de Catalunya, Spain

Steering Committee:

  • Ian F. Akyildiz, Truva Inc., USA
  • Wolfgang Gerstacker, Friedrich-Alexander University of Erlangen-Nuremberg, Germany
  • Chong Han, Shanghai Jiao Tong University, China

Scope:

Despite the successful roll-out of 5G wireless networks at frequencies spanning up to the millimeter-wave spectrum, the quest for increasing data rates persists. Towards this end, higher frequencies over the terahertz (THz) band (0.1-10 THz) will be central to ubiquitous wireless communications in 6G networks. In particular, THz frequencies promise to support ample spectrum, data rates approaching or even exceeding the 1 Terabit-per-second (Tbps) mark, massive connectivity, denser networks, and highly secure transmissions. Several unique challenges, however, have still to be addressed to achieve the full potential of THz communications. For instance, THz transmissions incur very high propagation losses, which significantly limit the communication distances. Furthermore, the coexistence of mmWave, sub 6GHz, and optical wireless communications and networking is not yet fully understood. On the other hand, emerging beyond-5G technologies such as reconfigurable intelligent surfaces, ultra-massive MIMO configurations, and integrated access and backhaul, can boost the gains of THz communications. At the algorithmic level, novel signal processing techniques and networking protocols can get around the THz quasi-optical propagation characteristics and mitigate microwave characteristics to enable seamless connectivity. The workshop aims to attract researchers and academics from various fields of study, ranging from THz materials and devices, to THz communications and networking.

WS-15: Workshop on Short Packet Communications for 6G Mission-Critical Applications

General Co-chairs:

  • Di Zhang, SMIEEE, SMEAI (EU), Zhengzhou University, China
  • Victoria Kostina, California Institute of Technology (Caltech), USA
  • Mahyar Shirvanimoghaddam, SMIEEE, The University of Sydney, Australia
  • Hyoungju Ji, SMIEEE, Samsung, South Korea

Scope:

ShortPacket-6G intends to leverage technological advancements and techniques to address fundamental, disruptive, as well as regular challenges arising in short packet communications for sixth generation (6G) mission-critical applications. In these regimes, the control commands and the device status updates are vastly transmitted with ultra-reliable and low latency communications (URLLC) requirements, which are with short block length that is comparable to the preamble length. It is difficult to appeal to coding methods in line with Shannon theorem to average out the thermal noise and channel propagation interference. We thus need to give some new fundamental theorems and related transmission mechanisms to cater to these trends. Apart from the URLLC requirements, information security/privacy are some other indispensable issues of the 6G mission-critical applications. Higher latency drawbacks due to processing procedures, redundancy bits of the current encryption/decryption mechanisms, and patch-based information security schemes turn out to be some inferior solutions. Besides, they are also invalid to intra-network attacks. Some novel information security/privacy methods that can be coalesced into the URLLC are needed.

Scope:

Future wireless networks are expected to ensure low latency, high reliability, scalability, as well as support enhanced quality-of-service and quality-of-experience in sophisticated scenarios arising from emerging multimedia applications and exponential increase in the number of smart sensors and devices. In such scenarios, optical wireless communication (OWC) gains importance where it can leverage the unique advantages of the light propagation medium as opposed to radio technologies, such as ultra-high capacity, immunity against electromagnetic interference, the possibility to communicate wirelessly through water, and the ability to provide an inherent physical security.  Furthermore, combining OWC with radio technology creates a synergy yielding a hybrid system with superior properties than the individual technologies could offer. Because of the numerous operational and technical advantages offered by OWC, we have been witnessing increased research and development activities in the past two decades, covering visible-light communications (VLC) and free space (FSO) communications for indoor and outdoor (including underwater and satellite) applications. Nevertheless, there exist still several technical challenges that need addressing before a wide-spread deployment of OWC.

Edge AI will accelerate the evolution of sensing capabilities, communication strategies, network optimizations, and application scenarios. However, edge AI will cause task-oriented data traffic flows over networks, for which disruptive communication techniques, efficient resource allocation methods and holistic system architectures need to be developed. The challenges for building edge AI ecosystems are multidisciplinary spanning wireless communications, machine learning, operation research, domain applications, regulations and ethics. The goal of this workshop is to bring together researchers and experts from academia and industry to consider edge AI opportunities across theoretical, algorithmic, systematic, and entrepreneurial considerations to embrace the exciting era of edge AI.

Scope:

There is rejuvenated interest in satellite communications & networking. Both the satellite and 3GPP industries aim at developing a seamlessly integrated one network. One main difference between the legacy satellite systems and the mega-constellations of the 6G era satellite system is the networking aspect with very high-speed inter-satellite links. For efficient operation, the network will have to be autonomous, intelligent, resilient, self-organizing & self-controlling to reduce the cost and risk of human intervention. Distributed decision making, fault recovery, resilience, and scalability are among the important features. These networks will rely on AI techniques at all levels: Ground operations, on-board operations, inter-satellite and satellite-to-ground links. The satellite mega-constellations in the 6G era will create unprecedented opportunities once the unprecedented challenges are addressed by the research community.

Scope:

Envisioned by the sixth generation (6G) of wireless networking, the human body becomes part of the network architecture that collects sensitive data for multiple purposes such as health and safety, aiming to enhance the quality of our lives. The 6G technology will be the fabric that can make newly-emerged technologies such as wearable devices, intelligent Internet of Medical Things (IoMT), and hospital-to-home (H2H) services become part of a unified network.  On the other hand, the vitality of e-health systems exacerbates the effect of adversarial attacks, such as eavesdropping, Man-in-the-Middle (MitM), and Denial-of-Service (DoS). To secure 6G-enabled e-health services, lightweight and scalable security mechanisms are highly required. The area of PHY layer security (PHY-Sec) plays a pivotal role in reducing both the latency as well as the complexity of novel security standards which is crucial for e-health vertical of 6G for providing promising solutions to secure the most critical and less-investigated network sectors in 6G, which are the ones corresponding to digital healthcare.

WS-20: Workshop on Intelligent and Cloud-based RAN

General Co-chairs:

  • Qi Sun, China Mobile Research Institute, China
  • Yongming Huang, Southeast University, China
  • Nurit Sprecher, Nokia Standards, Israel

Scope:

Driven by the diversified scenarios and services, as well as exponentially increasing mobile traffic, 5G networks are becoming more agile, software driven and virtualized. Building a highly competitive 5G with a large number of antennas and extremely flexible physical layer processing, supporting various spectrum bands, and deployment scenarios will add complexities and cost challenges. To manage this complexity, deliver services with agility and speed, and ensure economic sustainability, 5G networks design needs to embrace new cutting-edge technologies. Intelligence and cloudification are widely recognized as key driving forces in the evolution of 5G radio access networks. Wireless big data combined with AI/ML enables automation of the networks operations and allows building networks that support self-configuration, self-monitoring, self-healing and self-optimization without further human intervention. This will lead to significant reduction of OPEX and improvements in network performance and resource efficiency. Cloudification enables agile and on-demand placement, deployment, activation, scaling, de-activation and decommissioning of functional components (ideally lightweight, disaggregated into microservices) and rich platform services that can be used by applications (e.g., ML, big data). Furthermore, this will help speed-up innovation and open ‘beyond connectivity’ growth opportunities by intelligently connecting enterprise/vertical/OTT applications and communication service providers’ services.

This workshop explores the intelligent and cloud-based RAN. The proposed half-day workshop is to bring together researchers and experts from academia and industry to share the latest challenges, technologies, solutions, techniques and fundamentals pertaining to this cutting-edge research topic.

WS-21: Workshop on BlockSecSDN: Blockchain for Secure Software-defined Networking in Smart Communities

General Co-chairs:

  • Gagangeet Singh Aujla, Durham Univeristy, UK
  • Anish Jindal, University of Essex, UK
  • Neeraj Kumar, Thapar University, India
  • Harpreet Singh Dhilon, Virginia Tech, USA

Scope:

The emergence of SDN technology helps to isolate the control plane from the data plane and solves the issues through network programmability. The SDN is a centralized approach and easily modify the network topology, and besides, maintain data consistency and interoperability among heterogeneous IoT devices with the help of automation. Although SDN technology performs resilient and reliable connections in the heterogeneous environment based on secure communication protocols designed by the network programmers still chances of security threats may occur as a single controller is handling the complete network infrastructure. With the widespread adoption of wireless sensors in smart communities, device-to-device communication is susceptible to security vulnerabilities and resulting in devastating attacks on the network controller. Nowadays, Blockchain, a distributed ledger, is often linked to the financial service industry due to the concept of its underlying inception and the success, i.e, bitcoin. But, it is a wrong conception to confine blockchain to only one vertical. Contrary to popular opinion, blockchain can be closely associated with security and thereon can transverse across all the industries and smart communities. The distributed ledger shifts focus from a single and centralized point of failure towards a complex and intertwined decentralized model. Under this umbrella, one possibility is the blockchain for Secure SDN, and large scale network enterprises are already investing and exploring this opportunity.

WS-22: Workshop on Data Driven Intelligence for Networks and Systems (DDINS)

General Co-chairs:

  • Chuan Heng Foh, University of Surrey, UK
  • Xianfu Chen, VTT Technical Research Centre of Finland, Finland
  • Celimuge Wu, The University of Electro-Communications, Japan

Technical Program Chairs:

  • Chee Yen Leow, Universiti Teknologi Malaysia, Malaysia
  • Jinsong Wu, Guilin Univ. of Electronic Technology, China and Univ. of Chile, Chile
  • Zhi Liu, The University of Electro-Communications, Japan

Scope:

Network traffic is expected to grow exponentially in the next decade thanks to the advances in smart devices, Internet of Things (IoT) and cloud computing. Not only the volume of the traffic is increasing, the characteristics of the traffic are also becoming more diverse. While many advanced communication technologies have been proposed to push up the network capacity, increasing capacity alone is inadequate to deal with the traffic diversity. To properly manage traffic diversity, different but coherent strategies are needed at different protocol layers, and this often results in complex designs in the network which are difficult to deploy and manage. The recent advancement in artificial intelligence (AI) technology has provided a promising approach to deal with complex problems faced in the network design and operation. The trend towards highly integrated networks with diverse underlying access technologies to support simultaneously multiple vertical industries has demanded complex operation in the network. This represents a great challenge in network design.

WS-23: Workshop on Spectrum Sharing Technology for Next Generation Communications

General Co-chairs:

  • Yao Ma, National Institute of Standards and Technology, USA
  • Liuqing Yang, University of Minnesota, USA
  • David Griffith, National Institute of Standards and Technology, USA

Scope:

Due to the ever-increasing demands on wireless communications and limited radio spectrum resources, dynamic spectrum sharing (DSS) is a key solution to improve the ability of next generation (NG) wireless communications systems to monitor, access, use, and share spectrum. DSS requires new design, optimization and measurement processes as compared to current methods. There is an urgent need to develop standards and techniques for efficient DSS among heterogeneous systems and networks operating in licensed, unlicensed, license-assisted, or tiered-access bands, and to develop algorithms and hardware to conduct accurate sensing and measurement of spectrum use.

WS-24: Workshop on Wireless Propagation Channels for 5G and B5G

General Chair: Camillo Gentile (National Institute of Standards and Technology, Gaithersburg, Maryland, USA)

Scope:

The difficulties in wireless channel modeling are due to the complex propagation processes that form the basis of a wireless channel, involving reflections, scattering, diffraction, and transmission through a large number of irregular objects. For all practical purposes, it is thus necessary to derive simplified descriptions. The degree of admissible simplification, in turn, depends on the system for which the channel is intended. In the past decades, wireless systems have changed dramatically, from narrowband analogue systems, to MIMO wideband digital systems, and the deployment scenarios have expanded from cellular to WiFi, car-to-car, and internet of things. As the systems have evolved, so have the channel models needed for the design and evaluation. For this reason, measurement and modeling of propagation channels has remained a vibrant area, and in particular is important for the evaluation and deployment of 5G systems, and the design of emerging 6G systems.
