本文研究了下行非正交多址毫米波（mm-wave-NOMA）系统中用户聚类和功率分配的联合设计。为了减少系统开销，基站采用混合预编码技术，仅使用簇头(CH)的信道状态信息。为了最大化系统的总速率，针对某些目标质量不同的两种情况制定了基于Stackelberg博弈的优化问题：案例1侧重于提高CH的数据速率；案例 2 旨在当 CH 的数据速率受到限制时提高集群成员的速率。借助联盟博弈论，提出了一种低复杂度算法将用户动态分配到不同的集群中。然后，通过导出的闭式表达式获得每个簇中用户的最优功率分配系数。从Stackelberg平衡、复杂度、收敛性和稳定性方面分析了所提出的联合算法的特性。仿真结果表明：1）所提出的算法可以显着提高毫米波NOMA系统的总和率并降低中断概率；2）在两种情况下，NOMA在毫米波系统中的应用都能够比传统的基于正交多址的框架获得有希望的收益。
In this paper, the joint design of user clustering and power allocation is investigated in a downlink non-orthogonal multiple access-based millimeter wave (mm-wave-NOMA) system. To reduce the system overhead, hybrid precoding techniques are adopted at the base station by using the channel state information of cluster heads (CHs) only. In order to maximize the sum rate of the system, Stackelberg game-based optimization problems are formulated for two cases with different quality of some targets: Case 1 focuses on improving the data rates of CHs; and Case 2 aims to increase the rates of cluster members when the CHs’ data rates are caped. With the aid of coalitional game theory, a low complexity algorithm is proposed to dynamically allocate users into different clusters. Then, the optimal power allocation coefficients of the users in each cluster are obtained by the derived closed-form expressions. The properties of the proposed joint algorithms are analyzed in terms of Stackelberg equilibrium, the complexity, the convergence and the stability. The simulation results demonstrate that: 1) the proposed algorithms can significantly improve the sum rate and reduce the outage probability of the mm-wave-NOMA system and 2) the application of NOMA in mm-wave systems is capable of achieving promising gains over conventional orthogonal multiple access-based frameworks in both cases.
