Abstract: Abstract Due to the massive wireless traffic demand in fifth generation (5G) network, small cell have been attracted growing attention as a key solution and scalable approach for 5G deployments. However, to provide appropriate Quality of Service (QoS), mobile service providers need to study and analyze coverage with and without interference coordination. In this paper, we provide an analytical framework based on Stochastic Geometry to investigate downlink coverage analysis by taking into account mmWave and Nakagami fading. These metrics are analyzed with path loss laws in both cases namely; Line of Site (LOS) and Non Line of Site (NLOS). we derive a general expression of coverage probability according to signal-to-interference-plus-noise ratio (SINR) by assuming directional Beamforming. Then, downlink rate probability is obtained for good network reliability. Moreover, we propose an efficient approach to explore the coverage characteristics under cognitive interference coordination strategies. Finally, simulations results are verified using Monte Carlo Simulations.
