CAREER: Together We Rise: A Unified Multi-Input Multi-Output (MIMO) - Full Duplex Network Architecture

该项目旨在统一全双工（FD）通信和多输入多输出（MIMO）通信的能力，以允许灵活地使用可用的RF链来增加无线网络的容量和可靠性。多天线无线系统中的最新进展已经允许无线节点使用它们的所有天线用于发送（或接收），或者使用它们的一半用于发送而另一半用于接收。第一种系统被称为MIMO系统，而后者被称为全双工系统。传统上，MIMO和全双工被视为竞争技术。这项研究表明，它们可以以创新的方式组合在一起，与单独操作时相比，从根本上提高无线链路的容量。该组合允许节点动态地分配用于发送和接收的无线电资源。它进一步表明，通知路由和调度协议关于这种灵活的无线电资源特征可以显着提高网络容量。该研究提出了在当前无线网络架构中所需的硬件、协议和软件方面的创新，以实现显著的网络范围容量增加。因此，这项研究将产生高度灵活的无线电，将结合联合收割机全双工和MIMO。这种灵活性将允许未来的无线节点动态地分配无线电资源以用于同时发送和接收。其次，它将开发MAC和网络层协议，以充分利用这种灵活系统的优势。第三，它将开发一种新的网络模拟器，该模拟器将结合本研究提出的全新无线功能，以便能够有效地、更现实地研究先进的网络协议。

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.
