  Millimeter-wave (mm-wave) is a promising technique to enhance the network
capacity and coverage of next-generation (5G) based on utilizing a great number
of available spectrum resources in mobile communication. Improving the 5G
network requires enhancing and employing mm-wave beamforming channel
propagation characteristics. To achieve high data rates, system performance
remains a challenge given the impact of propagation channels in mm-wave that is
insufficient in both path loss, delay spread, and penetration loss. Additional
challenges arise due to high cost and energy consumption, which require
combining both analog and digital beamforming (hybrid beamforming) to reduce
the number of radio frequency (RF) chains. In this paper, the distributed
powers in the small cell to suppress path loss by specifying a considerable
power and controlling the distributed power to reduce the high cost and energy
consumption was proposed. The hybrid beamforming in mm-wave exploits a large
bandwidth which reduces the large path loss in Rayleigh fading channel. Also,
the trade-off between the energy consumption of RF chains and cost efficiency
depends on reducing the number of RF chains and the distributed number of
users. This paper finds that hybrid beamforming for massive multiple-input
multiple-output (MIMO) systems constitute a promising platform for advancing
and capitalizing on 5G networks
