Uplink Fractional Power Control and Downlink Power Allocation for Cell-Free Networks
IEEE Wireless Communications Letters, 2020 This letter proposes respective policies for uplink power control and downlink power allocation in cell-free wireless networks. Both policies rely only on large-scale quantities and are expressed in closed form, being therefore scalable.

Power Allocation in Cell-Free Massive MIMO: A Deep Learning Method
IEEE Access, 2020 Massive multiple-input multiple-output (MIMO) is a key technology in 5G. It enables multiple users to be served in the same time-frequency block through precoding or beamforming techniques, thus increasing capacity, reliability and energy efficiency.

Power Allocation in 5G Wireless Communication [PDF]
IEEE Access, 2019 Granger Causality analysis originated in the field of econometrics is used as a time series analysis tool based on vector auto-regression, and its phased generalized transfer entropy (TE), which is based on conditional co-information in information theory, has been widely used in data analysis in recent years.
