Assessing the Potential of Space-Time-Coding Metasurfaces for Sensing and Localization
Herman L. dos Santos, Martin Voigt Vejling, Taufik Abrão +1
Intelligent metasurfaces are one of the favorite technologies for integrating sixth-generation (6G) networks, especially the reconfigurable intelligent surface (RIS) that has been…
EMF Exposure Mitigation in RIS-Assisted Multi-Beam Communications
Herman L. dos Santos, Cristian J. Vaca-Rubio, Radosław Kotaba +3
This paper proposes a method for reducing {third-party} exposure to electromagnetic fields (EMF) by exploiting the capability of a reconfigurable intelligent surfaces' (RIS) to man…
LSTM-ACB-Based Random Access for Mixed Traffic IoT Networks
Herman L. dos Santos, João H. I. Souza, José Carlos Marinello +1
We propose a novel random access (RA) protocol that accounts for the network traffic in mixed URLLC-mMTC scenarios. By considering an IoT environment under high mMTC traffic demand…
LSTM-ACB-Based RA for IoT Mixed Traffic
Herman L. dos Santos, José Carlos Marinello, Cristiano Magalhaes Panazio +1
A novel random access (RA) scheme for mixed URLLC-mMTC traffic scenario is proposed using realistic statistical models, with the use mode presenting long-term traffic regularity. T…
OnRMap: An Online Radio Mapping Approach for Large Intelligent Surfaces
Herman L. Santos, Victor Croisfelt, Cristian J. Vaca-Rubio +2
We introduce OnRMap, an online radio mapping (RMap) approach for the sensing and localization of active users (AUs), devices that are transmitting radio signals, and passive elemen…
