Abstract
In response to the challenge of no difference coverage in seamless wide-area coverage scenarios, the 5G hyper-cellular network (HCN) is proposed to ensure user mobility and traffic continuity. In this network, Control Base Station (CBS) is responsible for control coverage, and the traffic base stations (TBSs) take care of high-speed data transmission. Firstly, this paper analyzes the spectral efficiency of different users by dividing the center region and edge region based on Poisson Voronoi Tessellation (PVT) model. For central users, a power control scheme is used to optimize the transmit power of TBSs. For edge users, a cooperative transmission technology and a power control scheme are employed to increase the spectral efficiency. In addition, the TBS sleeping strategy is used to further reduce inter-cell interference. Then, the analytical expressions of the spectral efficiency are derived by using random geometry. The simulation results illustrate that this scheme has a good effect on improving the spectral efficiency of the users with constant mobile velocity.
