Aiming at the problem of resource allocation in multi-user edge computing communication system,a task completion rate maximization scheme for unmanned aerial vehicle(UAV)assisted backscatter communication(BackCom)is proposed.A non-convex optimization problem is estab-lished with the UAV assisted mixed backscattering and active transmission edge calculation commu-nication system.The successive convex approximation(SCA)algorithm is used to convert the non-convex optimization problem into a convex optimization problem.Finally,the suboptimal solutions of reflection coefficient,active transmission transmit power,backscatter and active transmission time at each stage are obtained.Simulation results show that the proposed scheme is effective and reliable under different parameters.Compared with the two schemes of reflection and local computing,active transmission and local computing,the proposed scheme can effectively reduce the system energy consumption and maximize the user task completion rate.
