Rethinking Joint UAV Placement and Beamforming: A Correlation-Aware Geometric Approach
In multiuser unmanned aerial vehicle (UAV)-assisted downlink communications, UAV placement and transmit beamforming are inherently coupled through the propagation geometry. However, fully joint design based on instantaneous channel state information (CSI) is impractical, because…
