This paper proposes an orthogonal frequency division multiplexing (OFDM) relaying wireless power transfer based protocol for energy-constrained unmanned aerial vehicle (UAV) communication network. At the first step of the proposed protocol, the energy-constrained UAV separates the received signals into two disjoint subcarrier groups to perform energy harvesting (EH) and information decoding (ID). At the second step, UAV forwards the received information signals with the energy harvested a priori. Based on the proposed protocol, this paper aims to find the joint optimization of subcarrier grouping and power allocation for maximizing the transmission rate under the EH constraint. We further solve such a joint resource allocation problem via dual decomposition after transforming it into an equivalent convex optimization problem. Simulation results indicate that the performance of our proposed protocol can be significantly improved for the OFDM relaying based UAV communication network.
