We consider an uplink coordinated multi-point (CoMP) transmission from a user served by multiple base stations (BSs) which are connected to each other via a central unit (CU). We model the millimeter-wave communication link with Nakahami-m fading and random blockage. In this paper, we investigate the impact of blockage on the system ergodic capacity and try to find analytical formulation which can be useful in future optimization problems such as power control and resource allocations. The system performance is analyzed by deriving the probability density function of the received signal and finding closed form solution of ergodic capacity. Finally, the analytical results are compared with simulations and the impact of blockage is studied numerically. Numerical results show the efficiency of using CoMP in capacity improvement and reducing the blockage effect, as well as necessity of considering the blockage effect in performance analysis.
