Scheduling in Massive MIMO: User clustering and pilot assignment [PDF]
2016 54th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2016 In this paper, we consider the problem of user scheduling and pilot assignment in TDD multicell multiuser Massive MIMO systems. While in TDD systems the channel is acquired using uplink pilots, we propose a scheme that utilizes additional downlink probing in order to improve the spectral efficiency.

Utility-Based Downlink Pilot Assignment In Cell-Free Massive Mimo
CoRR, 2018 We propose a strategy for orthogonal downlink pilot assignment in cell-free massive MIMO (multiple-input multiple-output) that exploits knowledge of the channel state information, the channel hardening degree at each user, and the mobility conditions for the users.
