Abstract
This letter investigates resource allocation for users and small cell wireless backhaul in a reverse time division duplexing heterogenous network with 3D massive antennas at the macrocell base station. We first formulate the problem to maximize the summation of the logarithmic throughputs of all users, including the small cell users and macrocell users, considering backhaul limitation and resource allocation. To address the non-convex and non-linear optimization problem, we develop an iterative algorithm based on primal decomposition to find its solution. Simulation results demonstrate that the proposed algorithm benefits both cell edge and cell average performance.
