Sensing Assisted Satellite Backhaul with FBL UL and Broadcast DL for Massive IoT
Tijana Devaja, Milica Petkovic, Israel Leyva-Mayorga +2
Massive Internet of Things (IoT) networks operate with short packets whose reliability is limited by finite block- length (FBL) effects, while remote deployments increasingly rely…
A Game-Theoretic Perspective for Efficient Modern Random Access
Andreas Peter Juhl Hansen, Jeppe Roden Münster, Rasmus Erik Villadsen +4
Modern random access mechanisms combine packet repetitions with multi-user detection mechanisms at the receiver to maximize the throughput and reliability in massive Internet of Th…
Generative Network Layer for Communication Systems with Artificial Intelligence
Mathias Thorsager, Israel Leyva-Mayorga, Beatriz Soret +1
The traditional role of the network layer is the transfer of packet replicas from source to destination through intermediate network nodes. We present a generative network layer th…
Heterogeneous radio access with multiple latency targets
Israel Leyva-Mayorga, Jose Manuel Gimenez-Guzman, Lorenzo Valentini +1
Since the advent of ultra-reliable and low-latency communications (URLLC), the requirements of low-latency applications tend to be completely characterized by a single pre-defined…
Q-learning for distributed routing in LEO satellite constellations
Beatriz Soret, Israel Leyva-Mayorga, Federico Lozano-Cuadra +1
End-to-end routing in Low Earth Orbit (LEO) satellite constellations (LSatCs) is a complex and dynamic problem. The topology, of finite size, is dynamic and predictable, the traffi…
Query Timing Analysis for Content-based Wake-up Realizing Informative IoT Data Collection
Junya Shiraishi, Anders E. Kalør, Federico Chiariotti +3
Information freshness and high energy-efficiency are key requirements for sensor nodes serving Industrial Internet of Things (IIoT) applications, where a sink node must collect inf…
Random Access Protocol with Channel Oracle Enabled by a Reconfigurable Intelligent Surface
Victor Croisfelt, Fabio Saggese, Israel Leyva-Mayorga +3
The widespread adoption of Reconfigurable Intelligent Surfaces (RISs) in future practical wireless systems is critically dependent on the integration of the RIS into higher-layer p…
Federated Learning in Satellite Constellations
Bho Matthiesen, Nasrin Razmi, Israel Leyva-Mayorga +2
Federated learning (FL) has recently emerged as a distributed machine learning paradigm for systems with limited and intermittent connectivity. This paper presents the new context…
A Random Access Protocol for RIS-Aided Wireless Communications
Victor Croisfelt, Fabio Saggese, Israel Leyva-Mayorga +3
Reconfigurable intelligent surfaces (RISs) are arrays of passive elements that can control the reflection of the incident electromagnetic waves. While RIS are particularly useful t…
How to Identify and Authenticate Users in Massive Unsourced Random Access
Radosław Kotaba, Anders E. Kalør, Petar Popovski +4
Identification and authentication are two basic functionalities of traditional random access protocols. In ALOHA-based random access, the packets usually include a field with a uni…
Slicing a single wireless collision channel among throughput- and timeliness-sensitive services
Israel Leyva-Mayorga, Federico Chiariotti, Čedomir Stefanović +2
The fifth generation (5G) wireless system has a platform-driven approach, aiming to support heterogeneous connections with very diverse requirements. The shared wireless resources…
Reliability and Error Burst Length Analysis of Wireless Multi-Connectivity
Jimmy J. Nielsen, Israel Leyva-Mayorga, Petar Popovski
Multi-connectivity offers diversity in terms of multiple interfaces through which the data can be sent, thereby improving simultaneously the overall reliability and latency. This m…
Inter-plane satellite matching in dense LEO constellations
Beatriz Soret, Israel Leyva-Mayorga, Petar Popovski
Dense constellations of Low Earth Orbit (LEO) small satellites are envisioned to make extensive use of the inter-satellite link (ISL). Within the same orbital plane, the inter-sate…
