Description

Method and device for UAV millimeter wave beam training based on conformal antenna technical field [0001] One or more embodiments of this specification relate to the field of unmanned aerial vehicle communication technology, and in particular to a A method and device for millimeter-wave beam training of unmanned aerial vehicles. Background technique [0002] In the millimeter wave communication network of unmanned aerial vehicles, the dynamic changes of unmanned aerial vehicles are fast. When using millimeter wave communication, due to the millimeter wave The high frequencies and short wavelengths of UAVs and the directional beams used for communication make beam alignment between drones quite challenging. A conformal antenna is set up on the UAV, and the generated beam can cover almost all three-dimensional space. Codebook design, and beam training based on the designed codebook for 3D full-space millimeter wave beam alignment, In order to meet the requirements of m...
