Collaborative Research; RUI: Non-Orthogonal Multiple Access Pricing for Wireless Multimedia Communications

自成立以来，全球互联网流量一直在增加，预计未来还会增加更多。预计很大一部分互联网流量将来自无线视频。如此迅猛的数据流量增长和额外的高容量多媒体内容对设计满足移动多媒体用户体验质量要求的无线通信协议提出了重大挑战。本项目旨在探索利用经济理论为移动多媒体用户重新设计无线通信策略的新解决方案。低层向非正交多址的演进为支持无线多媒体通信带来了机遇和挑战。特别是，该项目将研究低层非正交多址无线多媒体通信的定价机制。该项目的成果将推动无线通信新领域的发现，共同利用以利润为中心的经济定价、以质量为中心的多媒体服务和非正交多址无线通信。本课题的研究目的是验证高水平定价模型和低水平非正交多址资源分配策略可以部分解决无线多媒体通信流量挑战的假设。本研究将建立一个新的非正交多址定价框架的理论基础，利用应用层经济来设计低层非正交多址无线多媒体通信算法。该项目包括三个基本要点：(1)创建以内容为中心的定价机制，意识到特定非正交多址资源块中承载的多媒体数据的重要性；(2)设计类似于Uber/Lyft拼车服务的以正交为中心的定价模型，考虑共享的非正交多址和独占的正交多址定价差异；(3)开发以激励为中心的非正交多址中继拍卖机制，在连续干扰消除期间利用中继节点上自然缓存的内容。研究成果将无缝整合到犹他谷大学（RUI -主要本科机构研究）和圣地亚哥州立大学（西班牙裔服务机构）的教育活动中。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Since its inception, the global internet traffic has been increasing and is projected to increase even more in the future. A significant portion of the internet traffic is expected to be due to wireless video. Such aggressive data traffic growth and additional high volume of multimedia content pose significant challenges in designing wireless communication protocols which meet the Quality of Experience requirements of mobile multimedia users. This project aims to explore new solutions leveraging economic theories to redesign wireless communication strategies for mobile multimedia users. The evolution to Non-Orthogonal Multiple Access at lower layers brings both opportunities and challenges to support wireless multimedia communications. In particular, this project will investigate pricing mechanisms for Non-Orthogonal Multiple Access wireless multimedia communications at lower layers. The outcome of this project will advance the discovery of new frontiers in wireless communications, jointly leveraging profit-centric economic pricing, quality-centric multimedia services, and Non-Orthogonal Multiple Access wireless communications.The research objective of this project is to test the hypothesis that the traffic challenge of wireless multimedia communication could be partially solved by jointly leveraging high level pricing models and low level Non-Orthogonal Multiple Access resource allocation policies. This research project will establish a theoretical foundation for a novel Non-Orthogonal Multiple Access Pricing framework, which exploits application layer economies in designing lower layer Non-Orthogonal Multiple Access wireless multimedia communication algorithms. The project consists of three essential thrusts: (1) creating a content-centric pricing mechanism, being aware of the importance of multimedia data carried within a specific Non-Orthogonal Multiple Access resource block; (2) designing an orthogonality-centric pricing model similar to Uber/Lyft rideshare service, being aware of the shared Non-Orthogonal Multiple Access and exclusive Orthogonal Multiple Access pricing differences; and (3) developing an incentive-centric Non-Orthogonal Multiple Access relay auction mechanism, leveraging the naturally cached content at relay nodes during successive interference cancellation. Research findings will be seamlessly integrated to education activities at Utah Valley University (RUI - Research in Primarily Undergraduate Institution) and San Diego State University (Hispanic Serving Institution).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
