摘　　要：针对时分双工正交频分多址无线传能使能移动边缘计算网络,研究联合多用户信道分配、上下行时间分配与功率控制以最小化系统能耗问题。由于所建模优化问题为混合整数非线性规划非凸问题,提出启发式信道分配算法与给定信道分配下的次优联合功率与上下行时间比例分割算法,并对算法性能进行仿真分析,验证了所提算法的有效性与相对于参考算法的性能增益。For the time division duplex orthogonal frequency division multiple access wireless power transfer enabled mobile edge computing networks, we study the problem of joint multi-user channel allocation, uplink and downlink time allocation and power control to minimize system energy consumption. Since the modeled optimization problem was a mixed integer nonlinear programming nonconvex problem, we proposed a heuristic channel allocation algorithm and a sub-optimal joint power and uplink-downlink time ratio splitting algorithm under a given channel allocation. The performance of the algorithm was simulated and analyzed to verify the effectiveness of the proposed algorithm and the performance gain relative to the reference algorithm.
