Abstract
When the UAV technology meets the multiple-input-multiple-output communications, the precoders for transmission need to fertilize the benefits of high-probability lineof-sight propagation paths. This work investigates the joint design of uplink/downlink precoders for single-cell UAV-mounted wireless systems. While the UAV has finite cruising endurance, the UAV-mounted base transceiver station can scavenge energy from wireless signals in the uplink period, and the deliver useful information to terrestrial users in the downlink period. By exploit the information-theoretical uplink-downlink duality, the weighted throughput can be maximized based on the tailored dirty paper coding scheme. Numerical results are used to demonstrated the effectiveness of the proposed algorithm.
