title = "Global EE optimization of massive MIMO systems",
abstract = "In this paper, we propose a power control algorithm for uplink and downlink multi-cell massive MIMO systems, where channel estimation error, pilot contamination and correlated channels are taken into account. Moreover, a closed-form power control algorithm under the assumption of equal power allocation for multiple users is provided. The simulation results show that equal power allocation is near optimal to maximize global EE for the system with zero-forcing detection/precoding, and is near optimal for the system with large number of antennas and MRC/MRT.",
