To relieve the stress on channel estimation and decoding complexity in cell-free massive multiple-input multiple-output (MIMO) systems, user grouping problem is investigated in this paper, where access points (APs) based on time-division duplex (TDD) are considered to serve users on different time resources and the same frequency resource. In addition, when quality of service (QoS) requirements are considered, widely-used max-min power control is no longer applicable. We derive the minimum… Expand

Optimal Power Control and Load Balancing for Uplink Cell-Free Multi-User Massive MIMO
This paper proposes an iterative elimination (IE) algorithm to remove ineffective BSs for each user in the cell-free (CF) multi-user (MU) massive multiple-input multiple-output system and shows that it is better than both maximum signal-to-noise ratio association and full-set joint transmission, especially in the high QoS regime.

It is proved that, in this game, the problem for each player to find a grouping strategy can be converted into the problem of searching for specific negative loops in the graph composed of users, and a greedy based suboptimal strategy to approach the optimal solution with polynomial time is designed.

On the Total Energy Efficiency of Cell-Free Massive MIMO
This work considers the cell-free massive multiple-input multiple-output (MIMO) downlink, where a very large number of distributed multiple-antenna access points (APs) serve many single-ant antenna users in the same time-frequency resource, and derives a closed-form expression for the spectral efficiency taking into account the effects of channel estimation errors and power control.
