该对应关系考虑非正交多址（NOMA）辅助移动边缘计算（MEC），其中功率和时间分配被联合优化以减少计算卸载的能耗。获得最佳功率和时间分配解决方案的封闭式表达式，并用于建立确定是否应使用传统正交多址（OMA）、纯NOMA或混合NOMA进行MEC卸载的条件。
This correspondence considers non-orthogonal multiple access (NOMA) assisted mobile edge computing (MEC), where the power and time allocation is jointly optimized to reduce the energy consumption of computation offloading. Closed-form expressions for the optimal power and time allocation solutions are obtained and used to establish the conditions for determining whether the conventional orthogonal multiple access (OMA), pure NOMA or hybrid NOMA should be used for MEC offloading.
