Abstract

One or more embodiments of the invention provide an unmanned aerial vehicle millimeter wave beam training method and device based on a conformal antenna, a conical conformal antenna is configured for an unmanned aerial vehicle, the beam coverage range can be expanded, and the effect of almost full-space coverage is achieved; a layered codebook of a binary tree structure is designed based on a conical conformal antenna; beam training is carried out based on the layered codebook to obtain an optimal beam between a sending end and a receiving end; information transmission is carried out with the optimal beam; a reliable communication link can be rapidly established for unmanned aerial vehicles of two communication parties; training overhead is reduced; and beam alignment is realized.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of UAV communication, and in particular to a method and device for training UAV millimeter wave beams based on conformal antennas. Background technique [0002] In the UAV millimeter-wave communication network, UAVs change rapidly. When millimeter-wave communication is used, due to the high frequency and short wavelength of millimeter waves, the beams used for communication are directional, making the beams between UAVs Alignment can be challenging. When a conformal antenna is set up on a UAV, the generated beam can almost cover the entire three-dimensional space. How to design a codebook based on the characteristics of the conformal antenna, and perform beam training based on the designed codebook, for use in three-dimensional full-space millimeter waves Beam alignment, so as to meet the requirements of millimeter wave high-speed transmission, is a key technology that needs t...
