The ever-changing diversity of users and high-specification devices have become key concerns for the current mobile network operators. In this paper, a max-min fair dynamic power control algorithm is proposed for the reduction of power consumption at a base station. The spatial heterogeneity of users is achieved by applying a stochastic geometry-based Cox process. The set-up network is analyzed using the mmWave spectrum at deployed small cells (SCs) and with sub-6 GHz in macrocell (MC). The simulated MATLAB results depict an increase in the network sumrate and average user throughput when changing from the fixed power allocation to the proposed dynamic power allocation algorithm.
