Zusammenfassung:The invention provides a task unloading method for a wireless network, and belongs to the technical field of communication, and the method comprises the steps: constructing and calculating an STAR-RIS-assisted unmanned aerial vehicle network model, a communication model and an energy consumption model, and determining a first objective function and a first constraint condition; for a task unloading problem, optimizing task unloading by utilizing a KKT condition to obtain an optimal task unloading decision vector; for a transmission resource problem, resource allocation is optimized by using a continuous convex approximation method SCA; and alternate solution is carried out until convergence, and an optimal solution of task unloading and resource allocation is obtained. The two sub-problems of task unloading and resource allocation are jointly optimized, the total energy consumption of the system is minimized, a hovering unmanned aerial vehicle equipped with a server is adopted as a base station, and the ampli
