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，预计未来将增加更多。互联网流量的很大一部分预计将来自无线视频。如此迅猛的数据流量增长和额外的大量多媒体内容给设计满足移动多媒体用户体验质量要求的无线通信协议带来了巨大的挑战。本项目旨在探索利用经济学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。向低层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，这个项目将研究在较低层的非正交多址无线多媒体通信的定价机制。该项目的研究成果将推动发现无线通信的新领域，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。本项目的研究目标是验证这样一种假设，即通过联合利用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地解决无线多媒体通信的流量挑战。本研究项目将为一种新颖的非正交多址接入定价框架奠定理论基础，该框架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。该项目包括三个关键步骤：(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携带的多媒体数据的重要性；(2)设计类似于Uber/Lyft拼车服务的以正交性为中心的定价模型，了解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接力拍卖机制，利用中继节点在连续干扰消除期间自然缓存的内容。研究成果将被无缝地整合到犹他州山谷大学(主要是本科院校的研究)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NSF的法定使命，并通过使用基金会的智力优势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.
