This work presents a technique for device-to-device (D2D) communication in a 5G mm-Wave network employing underlaying uplink channel. D2D communication portrays many advantages including increased throughput, lower latency, enhanced bandwidth, etc. But it is affected by the extensive pathloss attenuation while operating in 5G network at a frequency of 28 GHz. Thus, this scheme employs stochastic geometry to minimize the interference among the users. Partial resource multiplexing helps in minimizing the interference among the D2D users. Haversine formula is also applied for distance based interference reduction. Furthermore, Lagrangian optimization scheme is also employed for minimizing the D2D transmit power. Simulation results prove the efficacy of the proposed scheme.
