  With the maturity of unmanned aerial vehicle (UAV) technology, this work
investigates the integration of UAV into wireless communication systems. Since
the UAV is powered by a capacity-limited battery, this work proposes to use the
radio energy harvesting technology at the UAV in order to extend the lifetime
of UAV empowered base station. To extract the most weighted throughput of UAV
empowered wireless systems, the dirty paper coding scheme and
information-theoretic uplink-downlink channel duality are exploited to propose
an extracting the most weighted throughput algorithm. Numerical results are
used to verify the proposed algorithm.
