Abstract
In this paper, we consider a downlink Cloud Radio Access Network (Cloud-RAN) transmission, served by multiple beamformed remote radio head (RRHs) coordinated by base band units (BBUs), toward a typical mobile user. Assuming ultra-dense 5G and beyond network operating in millimeter wave (mm-Waves) bands, we modeled channels as a concatenation of Nakagami-m and binary blockage. In addition, it is assumed there are multiple interfering nodes nearby. We evaluate the system performance in terms of outage probability, after calculating channel distributions. Moreover, the impact of random blockage and interference on the performance of Nakagami-blockage channels with multiple RRHs are investigated by simulations.
