N2 - Device-to-Device (D2D) communication can enhance the spectrum utilization rate by multiplexing downlink resources in a 5G cellular network. However, it also introduces interference. We formulate an optimization problem with the objective of optimizing the transmission total rate of the celluar users (CUs) and D2D pairs while meeting the minimum necessary rate of cellular users and D2D pairs. We approach this issue by optimizing the transmitted beamforming, and power allocation jointly. The problem is decoupled into two subproblems. To achieve the optimization objective, a RPSO (Revised Particle Swarm Optimization Algorithm) in section beamforming optimization is formulated, and in the power allocation step the companion matrix is utilized to determine the optimal power allocation. The simulation demonstrates that the suggested approach successfully increased both the sum rate and connection rate while maintaining quality of service (QoS).
