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…
Autonomous RISs and Oblivious Base Stations: The Observer Effect and its Mitigation
Victor Croisfelt, Francesco Devoti, Fabio Saggese +3
Autonomous reconfigurable intelligent surfaces (RISs) offer the potential to simplify deployment by reducing the need for real-time remote control between a base station (BS) and a…
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…
Randomized Control of Wireless Temporal Coherence via Reconfigurable Intelligent Surface
João Henrique Inacio de Souza, Victor Croisfelt, Fabio Saggese +2
A reconfigurable intelligent surface (RIS) can shape the wireless propagation channel by inducing controlled phase shift variations to the impinging signals. Multiple works have co…
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…
Decentralized Design of Fast Iterative Receivers for Massive and Extreme-Large MIMO Systems
Victor Croisfelt, Taufik Abrão, Abolfazl Amiri +2
Despite the extensive use of a centralized approach to design receivers at the base station for massive multiple-input multiple-output (M-MIMO) systems, their actual implementation…
User-Centric Perspective in Random Access Cell-Free Aided by Spatial Separability
Victor Croisfelt, Taufik Abrão, José Carlos Marinello
In a cell-free massive multiple-input multiple-output (CF-mMIMO) network, multiple access points (APs) actively cooperate to serve users' equipment (UEs). We consider how the rando…
Accelerated Randomized Methods for Receiver Design in Extra-Large Scale MIMO Arrays
Victor Croisfelt Rodrigues, Abolfazl Amiri, Taufik Abrão +2
Massive multiple-input-multiple-output (M-MIMO) features a capability for spatial multiplexing of large number of users. This number becomes even more extreme in extra-large (XL-MI…
