This project seeks to unify the capability of full duplex (FD) communications and multi-input multi-output (MIMO) communications to allow a flexible way of using the available RF chains to increase the capacity and reliability of wireless networks. Recent advancements in multi-antenna wireless systems have allowed wireless nodes to use either all of their antennas for transmission (or reception), or to use half of them for transmission and the other half for reception. The first system is called a MIMO system and the latter is called a full duplex system. Traditionally, MIMO and full duplex have been seen as competing technologies. This research shows that they can be combined in innovative ways to fundamentally increase the capacity of a wireless link compared to the case when they operate separately. This combination allows a node to dynamically allocate radio resources for transmission and reception. It further shows that informing routing and scheduling protocols about this flexible radio resource feature can significantly improve network capacity. The research proposes innovations in the hardware, protocols and software needed in the current wireless network architecture to achieve significant network-wide capacity increases. Thus, this research will produce highly flexible radios that will combine full duplex and MIMO. This flexibility will allow future wireless nodes to dynamically allocate radio resources for simultaneous transmissions and receptions. Second, it will develop MAC and network layer protocols that can fully reap the benefits of this flexible system. Third, it will develop a new network simulator that incorporates the fundamentally new wireless features proposed by this research so that advanced network protocols can be effectively and more realistically studied.

该项目旨在统一全双工 (FD) 通信和多输入多输出 (MIMO) 通信的功能，以便以灵活的方式使用可用的 RF 链来提高无线网络的容量和可靠性。多天线无线系统的最新进展允许无线节点使用其所有天线进行传输（或接收），或者使用其中一半进行传输，另一半进行接收。第一个系统称为MIMO系统，后者称为全双工系统。传统上，MIMO 和全双工被视为竞争技术。这项研究表明，与单独运行的情况相比，它们可以以创新的方式组合起来，从根本上提高无线链路的容量。这种组合允许节点动态分配用于传输和接收的无线电资源。它进一步表明，向路由和调度协议通知这种灵活的无线资源特性可以显着提高网络容量。该研究提出了当前无线网络架构所需的硬件、协议和软件的创新，以实现网络范围内容量的显着增加。因此，这项研究将生产出高度灵活的无线电，将全双工和 MIMO 结合起来。这种灵活性将允许未来的无线节点动态分配无线电资源以进行同时传输和接收。其次，它将开发能够充分利用这一灵活系统优势的MAC和网络层协议。第三，它将开发一种新的网络模拟器，该模拟器融合了本研究提出的全新无线功能，以便可以有效、更现实地研究先进的网络协议。
