This project aims at addressing the fundamental problem of how to maximize the efficiency of access to the wireless medium. In recent years, new information-theoretic solutions have emerged, some of which can now be implemented due to technological advances. Also, long engrained notions, such as half duplex, are being challenged. It has been shown that through a combination of strategies at the physical layer and signal processing, full duplex systems are indeed feasible. These developments have radically altered the very notion of what a spatio-temporal resource is. These developments have necessitated a thorough redefinition and appraisal of the problem of efficient access as addressed in this project.Over the years, developments have taken place in parallel and somewhat in isolation in the physical layer community and in the protocol community. By bringing together a broad-spectrum of expertise from both areas, this project envisages fundamental advances in wireless networking at the access layer. The core challenge is how to use the scarce resources of 'space' and 'time' as efficiently as possible. In addition, distributed operation, channel fading, time-varying channel conditions, and fast time-scales of transmission opportunities and decisions, exacerbate the problem. This project has the potential of making a transformative advancement in the science of medium access.

该项目旨在解决如何最大限度地提高无线介质访问效率的基本问题。 近年来，出现了新的信息理论解决方案，其中一些现在可以实现由于技术进步。 此外，长期根深蒂固的概念，如半双工，正在受到挑战。 已经表明，通过物理层和信号处理策略的组合，全双工系统确实是可行的。这些发展从根本上改变了时空资源的概念。 这些发展需要彻底重新定义和评估的问题，有效的访问，在这个项目中所解决的。多年来，发展已经发生在平行和有点孤立的物理层社区和协议社区。通过汇集来自这两个领域的广泛专业知识，该项目设想在接入层无线网络的根本进步。 核心挑战是如何尽可能有效地利用“空间”和“时间”这两种稀缺资源。 此外，分布式操作、信道衰落、时变信道条件以及传输机会和决策的快速时间尺度加剧了该问题。 该项目有可能在媒体访问科学方面取得变革性进展。
