Abstract
In this paper, we consider the average spectrum efficiency of edge users under the random network model. In this model, the base stations (BSs) and the users exhibit Poisson distribution. By dividing the center and cell edge users, we use the multiple BSs that are closer to the edge users to cooperative with each other to transfer the users information to improve the average spectrum efficiency of the downlink edge users. We also adopt a distance-dependent power control scheme to further reduce inter-cell interference. Using the above method comprehensively, we derive the analytical expression of the spectral efficiency of the edge user. The performance of this scheme is evaluated through simulation results. Simulation results show that the spectrum efficiency is significantly improved compared to traditional user-centric transmission and non-power control cooperative schemes.
