摘要：
Network densification and 3D beamforming are two potential techniques to support the increasing data rate in the upcoming 5G cellular networks. This letter focuses on the joint optimization of 3D beamforming and resource allocation for the small cell (SC) backhaul in a heterogeneous network. After analyzing the achievable data rates of users and SCs based on Gamma distribution, we formulate a joint optimization problem to maximize the network throughput. We then convert it to an equivalent optimization problem and develop a low-complexity algorithm on joint 3D beamforming and resource allocation. Simulation results demonstrate the performance improvement of the proposed algorithm.
