标题： Power-Efficient Resource Allocation for MC-NOMA with Statistical Channel State Information

摘要： 在本文中，我们研究多载波非正交多址接入（MC-NOMA）系统的能效资源分配问题。 资源分配算法设计被建模为一个非凸优化问题，该问题考虑了发射端的统计信道状态信息和服务质量（QoS）约束。 为了在系统性能和计算复杂度之间取得平衡，我们提出了一种计算复杂度较低的次优功率分配和用户调度方案，以最小化总功率消耗。 所提出的方案利用了QoS需求的异质性来确定连续干扰消除解码顺序。 仿真结果表明，所提出的方案实现了接近最优的性能，并显著优于传统的正交多址接入（OMA）方案。 显示英文摘要

摘要： In this paper, we study the power-efficient resource allocation for multicarrier non-orthogonal multiple access (MC-NOMA) systems. The resource allocation algorithm design is formulated as a non-convex optimization problem which takes into account the statistical channel state information at transmitter and quality of service (QoS) constraints. To strike a balance between system performance and computational complexity, we propose a suboptimal power allocation and user scheduling with low computational complexity to minimize the total power consumption. The proposed design exploits the heterogeneity of QoS requirement to determine the successive interference cancellation decoding order. Simulation results demonstrate that the proposed scheme achieves a close-to-optimal performance and significantly outperforms a conventional orthogonal multiple access (OMA) scheme.
