摘要：

Three-dimensional (3D) beamforming and small cells are two effective techniques to meet the demand of explosive data rate in 5G wireless networks nowadays. The cooperation of these two schemes can help small cell involved heterogeneous networks (HetNets) to achieve high performance. In this paper, we investigate the performance of small cell in-band wireless backhaul in a downlink HetNet considering 3D beamforming. We first analyze the received signals of small cells and users for in-band small cell backhauling and then derive the closed-form achievable data rates for users and the overall system based on gamma distribution. Finally, we formulate the problem based on the derived achievable data rate, followed by analysis of the problem. Simulation results demonstrate that combining 3D beamforming with HetNets can significantly improve the system performance.
