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…

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…
