QoS and Sum Rate Maximization in Heterogeneous Massive MIMO Network

Fifth generation wireless communication aims at providing high data rate for long range signal transmission consuming high power in the network. The increase of power must be proficient considering the limitation of the interference without demolishing the quality of service in the network. This work can be analyzed by densifying the network using Massive MIMO with small cell access where maximum sum rate can be achieved. The work in this paper aims at providing better QoS by minimizing the total power and maximizing the sum rate in the heterogeneous network deployed with maximal ratio transmission beamforming technique. The simulation results of maximal ratio transmission prove that better sum rate can be achieved at the penalty of power consumption and it is compared with that of existing regularized zero forcing.
