The invention discloses a
millimeter wave full duplex unmanned aerial vehicle communication
relay transmission method, and belongs to the technical field of
millimeter wave communication. The method comprises the following steps: constructing a communication scene from a ground
base station to a ground user by taking an unmanned aerial vehicle as a
relay, and establishing a channel model of a downlink communication
system from the ground
base station to the user by taking the unmanned aerial vehicle as the
relay by utilizing a spatial position model; in the simultaneous same-frequency full duplex mode, enabling the ground
base station to transmit a
signal to the unmanned aerial vehicle, and enabling the unmanned aerial vehicle to transmit a
signal to
user equipment; designing the optimal position of the unmanned aerial vehicle under the ideal
beamforming condition, giving the position optimization
beamforming vector of the unmanned aerial vehicle, and giving the
beamforming vector to optimize the power of the base
station and the unmanned aerial vehicle transmitting
signal. According to the method, for a
downlink transmission system taking an unmanned aerial vehicle as a relay, thecoverage range of
millimeter wave communication is expanded, the communication capacity of the
system is improved, and optimal
power control under any given unmanned aerial vehicle relay position andbeam forming is provided.
