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.

该项目将通过利用访问和无线回程中的全双工传输来开发层次无线网络设计的基本原理。全双工在较短的范围内最有前途，因此与未来网络中预测的主要访问范围保持一致。此外，在基础架构到基础结构链接中，较大的全双工范围是可行的，因此非常适合回程链接。尽管全双工与层次网络的关键要素保持一致，但我们当前的设计原理是为半双链传输开发的，这是所有当前网络的基础。考虑到这一点，该项目将通过查看：（1）数据驱动的信号模型来解决层次完整网络的理论和协议，该模型是由节点自身传输到其自己的接收器引起的自我干扰的，（2）理论调度和路由的基础，利用自我干扰和多跳干扰取消的基础； （3）用于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中的基本设计约束之一，所有这些限制都是时间或频率的半双链。因此，它将重写无线网络基本面。此外，通过使用广泛的赖斯大学可编程测试床的重点，该项目将通过其公司合作伙伴影响无线网络的下一代。最后，项目团队将建立独特的大学间教育和研究计划，其中包括联合咨询和协作，为团队的补充专业知识提供咨询和利用。
