RIS-assisted Multiuser MISO Transmission and the Impact of Imperfect Channel Estimation
Ainna Yue Moreno-Locubiche, Josep Vidal, Antonio Pascual-Iserte +1
This paper proposes the joint design of reconfigurable intelligent surfaces (RIS) and zero-forcing (ZF) precoding for the downlink (DL) multiuser multiple-input single-output (MU-M…
Robust Design of Reconfigurable Intelligent Surfaces for Parameter Estimation in MTC
Sergi Liesegang, Antonio Pascual-Iserte, Olga Muñoz
This paper introduces a reconfigurable intelligent surface (RIS) to support parameter estimation in machine-type communications (MTC). We focus on a network where single-antenna se…

Rate Optimization for RIS-Aided mMTC Networks in the Finite Blocklength Regime
Sergi Liesegang, Alessio Zappone, Olga Muñoz +1
Reconfigurable intelligent surfaces (RISs) have become a promising candidate for the development of future mobile systems. In the context of massive machine-type communications (mM…
Approximations of the Aggregated Interference Statistics for Outage Analysis in Massive MTC
Sergi Liesegang, Antonio Pascual-Iserte, Olga Muñoz
This paper presents several analytic closed-form approximations of the aggregated interference statistics within the framework of uplink massive machine-type communications (mMTC),…
Entropy-Based Sensing Schemes for Energy Efficiency in Massive MTC
Sergi Liesegang, Antonio Pascual-Iserte, Olga Muñoz
Machine-type communications (MTC) are crucial in the evolution of mobile communication systems. Within this context, we distinguish the so-called massive MTC (mMTC), where a large…
