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…
XL-MIMO Energy-Efficient Antenna Selection under Non-Stationary Channels
Gabriel Avanzi Ubiali, Taufik Abrão
Massive multiple-input-multiple-output (M-MIMO) is a key technology for 5G networks. Within this research area, new types of deployment are arising, such as the extremely-large reg…
Stochastic Channel Models for Massive and XL-MIMO Systems
Lígia May Taniguchi, Taufik Abrão
In this paper, stochastic channel models for massive MIMO (M-MIMO) and extreme large MIMO (XL- MIMO) system applications are described, evaluated and systematically compared. This…
A Grant-based Random Access Protocol in Extra-Large Massive MIMO System
Otávio Seidi Nishimura, José Carlos Marinello Filho, Taufik Abrão
Extra-large massive multiple-input multiple-output (XL-MIMO) systems is a new concept, where spatial non-stationarities allow activate a high number of user equipments (UEs). This…
Antenna Selection for Improving Energy Efficiency in XL-MIMO Systems
José Carlos Marinello, Taufik Abrão, Abolfazl Amiri +2
We consider the recently proposed extra-large scale massive multiple-input multiple-output (XL-MIMO) systems, with some hundreds of antennas serving a smaller number of users. Sinc…
