Abstract

This paper proposes a novel architecture of multi-unmanned aerial vehicle (UAV)-enabled cloud radio access network (CRAN). In particular, we propose to deploy the UAVs as flying remote radio heads (RRHs) to serve ground user equipments (UEs). The baseband unit (BBU) is equipped with a large-scale antenna array to serve the flying RRHs and affords all the baseband signal processing. To optimize the proposed architecture, we consider the maximization of the minimum rate of UEs by jointly optimizing UAVs placement, quantization noise variance, and power control. The corresponding optimization problem is not convex and to solve it we devise an efficient iterative algorithm combining the block coordinate descent and successive convex optimization methods. Numerical results demonstrate the superior performance of the proposed algorithm compared to two benchmark schemes.
