为了解决未来几代无线网络中移动的用户数量的爆炸性增长，非正交多址接入（NOMA）受到了极大的关注。在这项工作中，我们提出了一个激励驱动的内容转移框架，以奖励用户，推动多媒体数据内容从正交多址接入（OMA）链路到NOMA链路。该框架的目标是通过同时提高用户的体验质量（QoE）和基站的利润来使用户和基站两者受益。研究了如何在NOMA和OMA链路之间进行数据的策略性分割以获得最佳服务的关键问题。根据我们的研究，OMA可以用于传输重要帧，而NOMA适用于重要性较低的帧。利用博弈论的方法，我们开发了一种方法，以达到纳什均衡的解决方案。仿真研究显示了建议的激励机制，以鼓励用户通过NOMA链接传输某些数据的优点和潜力。
To address the explosive growth of number of mobile users in future generations of wireless networks, Non-Orthogonal Multiple Access (NOMA) has received significant attention. In this work, we propose an incentive driven content shifting framework to reward users which push multimedia data content from an Orthogonal Multiple Access (OMA) link to a NOMA link. The objective of the framework is to benefit both the user and the base station by simultaneously improving the user’s Quality of Experience (QoE) and the base station’s profits. The key issue of strategically splitting the data among the available NOMA and OMA links are studied to attain the best possible service. According to our study, OMA could be leveraged for transmission of important frames while NOMA is suitable for frames with lesser importance. Using game theoretic methods, we develop a method to attain the Nash Equilibrium of the solution. Simulation studies showcase the merits and potentials of the proposed incentive mechanism to encourage users transmitting certain data through NOMA links.
