TUT-01: Spectrum Coexistence in Modern and Future Wireless Networks
Monday, June 24 | 8:30 - 10:00
ABSTRACT
The wireless spectrum has become a valuable resource due to the increasing capacity demands in modern wireless technologies. While it is commonly known for its importance in the context of cellular communications, it is also significantly important in many other applications such as WiFi, satellite communications, radio altimiter, to name a few. Hence, it is particularly important to regulate the use of such an important resource among different applications. Additionally, it is important to design smart coexistence solutions between different technologies in a way that ensures a certain level of performance quality for each of these coexisting technologies. For instance, 5G communication systems can cause harmful interference to radio altimiter, which is used by aircrafts to estimate their altitude during take off and landing. Similarly, while 28-GHz band is licensed for fixed satellite services for Earth-to-space uplink transmissions, it is also used by the terrestrial cellular and backhaul networks for downlink operation. Another example is the 6-GHz which has recently been unlocked for unlicensed use by WiFi and cellular networks, in addition to incumbent applications which includes fixed point communications such as wireless backhaul. Hence, it is important to model, analyse, and design coexistence techniques for each of the aforementioned scenarios while accurately capturing the imposed regulations.
In this tutorial, we discuss analytical approaches that enable designing such techniques in a tractable way, lending useful insights to the network designers. In particular, we cover each of the coexistence scenarios provided above in addition to providing a detailed description of how stochastic geometry can be used to provide a framework that helps in modelling and designing an efficient coexistence technique.

TUT-02: Towards Integrated, Intelligent and Ubiquitous 6G Connectivity
Monday, June 24 | 10:30 - 12:00
ABSTRACT
Following the recently adopted IMT-2030 framework by ITU-R, several major technologies of integrated sensing and communications (ISAC), intelligent metasurfaces (IM), such as reconfigurable intelligent surfaces (RIS), and nonterrestrial networks (NTN) for integrated, intelligent and ubiquitous 6G connectivity have emerged which herald a new era by transcending conventional communication networks and infrastructure to highly energy efficient, with ultrahigh data rates, shared hardware and spectral resources, smart radio environment, with exploration of high frequency bands such as centimeter wave (cmWave), terahertz (THz), and multiple use cases for 6G, such as ISAC for robotics, and NTN for public safety. The amalgamation of these technologies, such as IM-assisted ISAC, NTN with ISAC signalling, IM aided NTN-TN integration, will also provide a paradigm shift to the way we communicate wirelessly today. Early study items on ISAC are being carried out in 3GPP Rel. 19 to support communications-assisted sensing, and sensing assisted communications. While since 3GPP Rel. 17, NTN technology is one of the major technologies considered for global connectivity. In this direction, evolving signal processing methods, edge-cloud computing, AI and next generation multiple access (NGMA)-assisted deployments for low Earth orbit (LEO) satellites and unmanned aerial vehicles (UAVs)/flying platforms, have drastically changed the current realization of the space, sky and terrestrial communication networks. Besides, interference management using NGMA approaches such as rate-splitting multiple access, becomes important for multibeam multicast LEO satellites in NTN. This tutorial presents a comprehensive overview of emerging solutions, vision, trends, fundamentals, challenges, use cases, technology synergies among ISAC, IM and NTN, to provide integrated, intelligent and ubiquitous 6G connectivity.

TUT-03: Towards Ultra Reliable Wi-Fi
Monday, June 24 | Part 1 - 13:00 - 14:30
Monday, June 24 | Part 1 - 15:00 - 16:30
ABSTRACT
Typically, achieving highly reliable data transmission means ensuring a high probability of data delivery. With sufficient leeway in the delay constraints, reliable delivery can be easily provided with retransmission of undelivered packets. However, this problem changes drastically if delay budgets are small. This challenge is known as ultra-reliable low-latency communications in 5G or support of real-time applications in the Wi-Fi 7 domain. In Wi-Fi networks, which currently handle about half of all user traffic, the primary obstacles to timely packet delivery include random access issues, interference, and traffic surges. With the rising popularity of Cloud VR applications, online gaming, and industrial automation, the demands for low latency, minimal packet loss, and high throughput are becoming increasingly challenging.
In this tutorial, we will explore strategies to satisfy these demands consistently for any user, at any time, and in any location. We will explain the main features of modern Wi-Fi, including MU-MIMO and OFDMA, multi-link operation and so others introduced in the recently released IEEE 802.11ax standard aka Wi-Fi 6 and IEEE 802.11be aka Wi-Fi 7 that is under development now. We will explain, why they cannot guarantee quality of service for real-time applications, though the latter is its key target. Finally, we will describe how the Wi-Fi 8 technology, the development of which commenced in 2023, aims to tackle this challenge by promising ultra-high reliability.
We will consider how promising approaches are being implemented in the future Wi-Fi standard, what and why is left beyond the scope of the standard, and how the research community can contribute to maximizing user experience in Wi-Fi networks.
