Uplink Multiplexing of eMBB/URLLC Services Assisted by Reconfigurable Intelligent Surfaces
João Henrique Inacio de Souza, Victor Croisfelt, Radosław Kotaba +2
This letter proposes a scheme assisted by a reconfigurable intelligent surface (RIS) for efficient uplink traffic multiplexing between enhanced mobile broadband (eMBB) and ultra-re…
On the Impact of Control Signaling in RIS-Empowered Wireless Communications
Fabio Saggese, Victor Croisfelt, Radosław Kotaba +3
The research on Reconfigurable Intelligent Surfaces (RISs) has dominantly been focused on physical-layer aspects and analyses of the achievable adaptation of the wireless propagati…
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…
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…
Deterministic Patterns for Multiple Access with Latency and Reliability Guarantees
Radosław Kotaba, Roope Vehkalahti, Čedomir Stefanović +2
We study a scenario in which multiple uncoordinated devices aim to achieve reliable transmissions within a given time frame. The devices are intermittently active and access a shar…
Common Message Acknowledgments: Massive ARQ Protocols for Wireless Access
Anders E. Kalør, Radosław Kotaba, Petar Popovski
Massive random access plays a central role in supporting the Internet of Things (IoT), where a subset of a large population of users simultaneously transmit small packets to a cent…
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…
How URLLC can Benefit from NOMA-based Retransmissions
Radosław Kotaba, Carles Navarro Manchón, Tommaso Balercia +1
Among the new types of connectivity unleashed by the emerging 5G wireless systems, Ultra-Reliable Low Latency Communication (URLLC) is perhaps the most innovative, yet challenging…
Wireless Mesh Networking with Devices Equipped with Multi-Connectivity
Israel Leyva-Mayorga, Radoslaw Kotaba, Fresia Maria +1
Wireless connectivity is rapidly becoming ubiquitous and affordable. As a consequence, most wireless devices are nowadays equipped with multi-connectivity, that is, availability of…
Non-Orthogonal Contention-Based Access for URLLC Devices with Frequency Diversity
Christopher Boyd, Radosław Kotaba, Olav Tirkkonen +1
We study coded multichannel random access schemes for ultra-reliable low-latency uplink transmissions. We concentrate on non-orthogonal access in the frequency domain, where users…
