9:00-9:45am, Keynote: Petar Popovski, "A Prospect in Wireless Research: Embracing Heterogeneous Connectivity"

Abstract: The wireless landscape evolves towards supporting a large population of connections for humans and machines with very diverse features and requirements. An important step in embracing heterogeneous connectivity has been the definition of the three cornerstone services in 5G: enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). However, this classification is rather limited and is currently undergoing a revision within the research community. Service heterogeneity can be accommodated by network slicing, through which each service is allocated resources to provide performance guarantees and isolation from the other services. Nevertheless, slicing gets a completely new dimension in the context of the shared, interfering nature of the wireless medium. For example, what is the tradeoff when two links are sharing the wireless medium, where one link requires low latency and the second link requires a high rate? This talk will address this type of questions and shed light on the research challenges and opportunities in addressing those questions. Overall, supporting assorted connectivity types in a shared wireless spectrum is an important prospect for connectivity beyond 5G.

9:45-10:10am, Majid Butt, "NR Light: The missing link in 5G NR Landscape"

Abstract: (Ultra-reliable low-latency communications) URLLC and massive machine-type communications (mMTC) applications have emerged as key differentiator for 5G communication as compared to previous generations of mobile communication where focus was broadband communication. URLLC focuses on high reliability and low latency application use cases, while mMTC focuses on machine type communication with stringent requirements on energy saving and limited communication ability. However, there are application use cases whose requirements lie in between these use cases and 3GPP Release 16 (and beyond) studies such use cases under the umbrella of NR light, recently renamed as reduced capability UEs. This talk will motivate for the need for NR light in 3GPP and introduce recent communication techniques under investigation to meet the requirements of these use cases.

10:10-10:35am, Maxime Guillaud, "Tensor-Based Modulation for Unsourced Massive Random Access"

Abstract: We introduce a modulation for unsourced massive random access whereby the transmitted symbols are rank-1 tensors constructed from Grassmannian sub-constellations. The tensors structure allows to multiplex the users in a nonlinear way and enables the use of tensor decomposition in order to separate the users at the receiver, allowing a convenient uncoupling between multi-user separation and single-user decoding. The proposed signaling scheme generalizes gracefully to fading channels and multiple-antenna settings, and is shown to perform well in comparison to state-of-the-art unsourced approaches.

10:35-11:00am, Arsenia (Ersi) Chorti, "Security in B5G low latency scenarios"

Abstract: With the emergence of URLLC and mMTC, corresponding low complexity and low latency security mechanisms are needed. Promising lightweight mechanisms include physical unclonable functions (PUF), secret key generation (SKG) at the physical layer and localization based authentication, as considered in this talk. We will demonstrate how physical layer security (PLS) allows building a new breed of low latency security schemes, such as zero-round-trip-time (0-RTT) resumption authentication protocols combining PUF and SKG processes. Furthermore, hybrid PLS and crypto schemes, such as authenticated encryption (AE) using SKG, will be introduced. We will conclude this talk with a discussion on future directions in 6G security.

11:00-11:25am, Mohammad Assaad, "Age of information (AoI) in communication networks"

Abstract: Age of Information (AoI) is a novel metric that quantifies the freshness of information, which is of particular importance in real-time applications. AoI was mainly motivated by a variety of new applications requiring fresh information at a monitor to accomplish specific tasks, and it is currently gaining interests in several areas such as networked monitoring, robotic networks, Internet of Things, vehicular control, etc. AoI can be considered as a fundamental performance metric in communication networks, and recent results have shown that some well-known design principles (e.g. sampling, scheduling, access, etc.) need to be re-examined in order to improve the information freshness in the network. In this talk, we will provide an overview of some recent results in the area of AoI in communication networks, with a main focus on multiuser scheduling and access control techniques, and identify some open problems.

11:25 am-11:50am, Leila Musavian, "Challenges for Low Latency Communications for Beyond 5G: How to Analyse the performance"

Abstract: We witness a surge of low latency or ultra-low latency applications for 5G (beyond 5G) communications systems. Also, most of the time, there exists other constraints in the system, either in terms of the available resources (e.g., limited available energy in low battery devices) or QoS requirements (e.g., Throughput, reliability, etc.). Enabling low latency communications has been an important research topic in communications society. One of the challenges in this is how to analyse the performance of such system. In this talk, we discuss some of the challenges and present useful mathematical frameworks for analysing performance of LLC systems.
