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…
Distributed Receivers for Extra-Large Scale MIMO Arrays: A Message Passing Approach
Abolfazl Amiri, Sajad Rezaie, Carles Navarro Manchon +1
We study the design of receivers in extra-large scale MIMO (XL-MIMO) systems, i.e. systems in which the base station is equipped with an antenna array of extremely large dimensions…
Outage Analysis of Downlink URLLC in Massive MIMO systems with Power Allocation
Alexandru-Sabin Bana, Luca Sanguinetti, Elisabeth De Carvalho +1
Massive MIMO is seen as a main enabler for low latency communications, thanks to its high spatial degrees of freedom. The channel hardening and favorable propagation properties of…
Deep Learning Based Spatial User Mapping on Extra Large MIMO Arrays
Abolfazl Amiri, Carles Navarro Manch'on, Elisabeth de Carvalho
In an extra-large scale MIMO (XL-MIMO) system, the antenna arrays have a large physical size that goes beyond the dimensions in traditional MIMO systems. Because of this large dime…
Achieving Fair Random Access Performance in Massive MIMO Crowded Machine-Type Networks
José Carlos Marinello, Taufik Abrão, Richard Demo Souza +2
The use of massive multiple-input multiple-output (MIMO) to serve a crowd of user equipments (UEs) is challenged by the deficit of pilots. Assuming that the UEs are intermittently…
A Message Passing Based Receiver for Extra-Large Scale MIMO
Abolfazl Amiri, Carles Navarro Manch'on, Elisabeth de Carvalho
We consider a massive MIMO system where the array at the access point reaches a dimension that is much larger than the array in current systems. Transitioning to an extremely large…
