User-Centric 5G Cellular Networks: Resource Allocation and Comparison With the Cell-Free Massive MIMO Approach (2018, methodology): “To overcome this limitation, the a user-centric (UC) distributed massive MIMO system has been introduced, still for single-antenna APs and MSs, in [15]; in the UC approach, each MS is served not by all the APs in the system, but just by the ones that are in the neighborhood.”
Cell-Free Massive MIMO: A New Next-Generation Paradigm (2019, methodology): “The selected-AP based approach outperforms the all-AP based approach in terms of the 95%-likely per-user rate even with the aid of simple channel estimation algorithms, as described in [18].”

Massive MIMO is a Reality - What is Next? Five Promising Research Directions for Antenna Arrays (2019, background): “as ZF and MMSE processing, in a distributed or hierarchical way. When the channel gain variations are large over the array, it might only be worthwhile to let a part of the ELAA serve each user [39], [80]. It is not the computational complexity that is the issue but the front-haul capacity requireme”
