Coordinated Hybrid Precoding Design in Millimeter Wave Fog-RAN [PDF]
IEEE Systems Journal, 2020 In this paper, we propose a femto base station cluster (FBSC)-based fog radio access network (F-RAN) structure, where multiple femto base stations (FBSs) coordinately serve users in each FBSC with the millimeter wave band. In addition, the FBS head (FBSH) in each FBSC receives data from the central processor (CP) via fronthaul link with the microwave ...
