    Abstract

    This work deals with a joint downlink and uplink design for wireless powered cloud radio access network, where a baseband processing unit (BBU) communicates with downlink and uplink users through multiple remote radio heads (RRHs) connected to the BBU via finite-capacity fronthaul links. In the downlink, the RRHs send information to the downlink users and transfer energy to the uplink users (ULUs). By using the harvested energy, each ULU transmits information to the BBU through the uplink channels. In this work, we maximize the uplink sum-rate of the ULUs subject to the minimum downlink rate constraint as well as the per-node transmit power and the fronthaul capacity constraints. Numerical results confirm the advantages of the proposed algorithm compared to baseline schemes.
