Heterogeneous cellular networks (HetNets) consist of different tiers of base stations (BSs) to meet the ever-increasing mobile traffic demand. Random deployment of various BSs has mostly been assumed to satisfy a Poisson point process (PPP). However, low power small cells are usually clustered around the popular areas, and PPP does not reflect such a feature. To this end, in this paper, we consider base station (BS) cooperation and analyze user rate and energy efficiency of the HetNets based on a specifical Poisson cluster process (PCP). A calculable formula for spectral efficiency is derived. Simulation results are consistent with the numerical analysis, which confirms the accuracy of theoretical formulas.
