Pilot-Free Predictive Multi-User Beamforming via Sensing Management in Cell-Free Networks
Eren Berk Kama, Murat Babek Salman, Isaac Skog +1
This paper presents a sensing management frame- work for integrated sensing and communications (ISAC) within cell-free massive multiple-input multiple-output (MIMO) systems to redu…
Multi-Antenna Users in Cell-Free Massive MIMO: Stream Allocation and Necessity of Downlink Pilots
Eren Berk Kama, Junbeom Kim, Emil Björnson
We consider a cell-free massive multiple-input multiple-output (MIMO) system with multiple antennas on the users and access points (APs). In previous works, the downlink spectral e…
Sensing Management for Pilot-Free Predictive Beamforming in Cell-Free Massive MIMO Systems
Eren Berk Kama, Murat Babek Salman, Isaac Skog +1
This paper introduces a sensing management method for integrated sensing and communications (ISAC) in cell-free massive multiple-input multiple-output (MIMO) systems. Conventional…
Downlink Pilots are Essential for Cell-Free Massive MIMO with Multi-Antenna Users
Eren Berk Kama, Junbeom Kim, Emil Björnson
We consider a cell-free massive MIMO system with multiple antennas on the users and access points. In previous works, the downlink spectral efficiency (SE) has been evaluated using…
