The invention discloses a method and system for carrying out relay forwarding based on a communication and sensing integrated unmanned aerial vehicle, the communication and sensing integrated unmanned aerial vehicle is used as a relay node, and based on sensed information such as user position and orientation, millimeter wave beams pointing to a user are formed by utilizing a passive beam forming technology of an intelligent reflecting surface on the unmanned aerial vehicle; by adjusting the passive beam direction and combining with the centimeter wave feedback signal of the user, the angle direction with the maximum receiving power at the user is obtained, and the angle correction is calculated. According to the method and the system for relay forwarding based on the communication-sensing integrated unmanned aerial vehicle, the influence of sensing errors of a communication-sensing integrated technology can be suppressed, and the millimeter wave communication quality of the unmanned aerial vehicle relay node is ensured.
