This paper investigates the benefit of coordinated multipoint transmission (CoMP) in a User-Centered Cloud-based Radio Access Network (UC-CRAN). In UC-CRAN, virtual cells (also called service zones) are created around a user effectively changing the center of network operation from "always ON" base stations to user demands. The user-centered architecture potentially removes cell-edge users due to the spatial repulsion between service zones, thereby limiting the potential of CoMP which is effective in networks with cell-edge interference. To this end, we derive an analytical framework to model the area spectral efficiency (ASE) and energy efficiency (EE) in UC-CRAN with CoMP. Further, the investigation encompasses analyzing the impact of CoMP in UC-CRAN on ASE and EE with the change in service zones size and data base station (DBS) deployment density. The proposed analytical method is …
