Non-orthogonal multiple access techniques have been proposed recently for 5G wireless systems and beyond to improve access efficiency by allowing many users to share the same spectrum. Due to the strong co-channel interference among mobile users introduced by NOMA, it poses significant challenges for system design and resource management. This article reviews resource management issues in NOMA systems. The main taxonomy of NOMA is presented by focusing on the two main categories of resource reuse: power-domain and code-domain NOMA. Then a novel radio resource management framework is proposed based on game-theoretic models for uplink and downlink transmissions. Finally, potential applications and open research directions in the area of resource management for NOMA are provided.

5G 及以上非正交多址网络中的资源管理


最近针对 5G 无线系统及其他系统提出了非正交多址技术，通过允许许多用户共享相同的频谱来提高接入效率。由于NOMA引入的移动用户之间强烈的同频干扰，给系统设计和资源管理带来了重大挑战。本文回顾 NOMA 系统中的资源管理问题。 NOMA 的主要分类是通过关注资源重用的两个主要类别来呈现的：功率域和码域 NOMA。然后，基于上行链路和下行链路传输的博弈论模型，提出了一种新颖的无线电资源管理框架。最后，提供了 NOMA 在资源管理领域的潜在应用和开放研究方向。
