In this article, a joint resource allocation of power, time, and sub-channels that minimizes the total energy consumption of users for Hybrid NOMA MEC Offloading is proposed. By formulating and solving the joint optimization problem, first we propose a novel optimal Hybrid NOMA scheme referred to as Switched Hybrid NOMA (SH-NOMA) for power and time allocation. Subsequently, we address sub-channel allocation as a three-dimensional assignment problem, and propose the Total-Reward Exchange Stable (TES) algorithm to solve it. Analytically, we show that SH-NOMA is more energy efficient than the Hybrid NOMA scheme in the literature and that the TES algorithm converges to a solution with less energy consumption than the widely used two-sided exchange stable algorithm. Finally, via simulations we demonstrate that the proposed methods outperform the results in the literature.

一种混合 NOMA MEC 卸载的联合资源分配方法

在本文中,提出了一种功率、时间和子信道的联合资源分配,以最小化混合 NOMA MEC 卸载的用户总能耗。通过制定和解决联合优化问题,我们首先提出了一种新的最优混合 NOMA 方案,称为开关混合 NOMA (SH-NOMA),用于功率和时间分配。随后,我们将子通道分配作为一个三维分配问题,并提出了总回报交换稳定(TES)算法来解决它。分析表明,SH-NOMA 比文献中的 Hybrid NOMA 方案更节能,并且与广泛使用的双边交换稳定算法相比,TES 算法收敛到能耗更低的解决方案。最后,
