This project will develop foundational principles for hierarchical wireless network design by leveraging full-duplex transmissions in both access and wireless backhaul. Full-duplex is most promising at shorter ranges, and hence is fortuitously aligned with the predicted dominant access range in future networks. Furthermore, larger full-duplex ranges are feasible in infrastructure-to-infrastructure links, and hence are well suited for backhaul links. While full-duplex is well-aligned with the key elements of hierarchical networks, our current design principles are largely developed for half-duplex transmissions which is the basis for all current networks. With that in mind, this project will address both theory and protocols for hierarchical full-duplex networks by looking at: (1) data-driven signal models for self-interference caused by the node's own transmission to its own receiver, (2) theoretical foundations for scheduling and routing that leverage both self-interference and multi-hop interference cancellation; and (3) protocols and prototypes for network scale full-duplex resource management. Full-duplex breaks one of the basic design constraints in current wireless networks, all of which are either half-duplex in time or frequency; it will therefore rewrite wireless networking fundamentals. Further, with emphasis on realizable networks using extensive Rice University's programmable testbeds, the project will impact the next-generation of wireless networks via its corporate partners. Finally, the project team will establish a unique inter-university education and research program, which will include joint advising and collaborative advising and leverage the team's complementary expertise.

该项目将通过在接入和无线回程中利用全双工传输，开发分层无线网络设计的基本原则。全双工技术在较短的范围内最有前途，因此它与未来网络中预测的主要访问范围一致。此外，在基础设施到基础设施的链路中，更大的全双工范围是可行的，因此非常适合回程链路。虽然全双工很好地符合分层网络的关键要素，但我们目前的设计原则主要是针对半双工传输而开发的，而半双工传输是所有当前网络的基础。考虑到这一点，本项目将通过以下研究来解决分层全双工网络的理论和协议：(1)由节点自身传输到自己的接收器引起的自干扰的数据驱动信号模型，(2)利用自干扰和多跳干扰消除的调度和路由的理论基础；(3)网络规模全双工资源管理的协议和原型。全双工打破了当前无线网络的一个基本设计限制，即所有无线网络在时间或频率上都是半双工；因此，它将改写无线网络的基本原理。此外，该项目强调使用莱斯大学广泛的可编程测试平台来实现网络，将通过其企业合作伙伴影响下一代无线网络。最后，项目团队将建立一个独特的大学间教育和研究计划，其中将包括联合咨询和合作咨询，并利用团队的互补专业知识。
