项目摘要

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程度地提高访问无线介质效率的基本问题。近年来，出现了新的信息理论解决方案，现在可以根据技术进步来实施其中一些。同样，长期以来的概念，例如半双工，也受到挑战。已经表明，通过物理层和信号处理的策略组合，完整的双链系统确实是可行的。这些发展从根本上改变了时空资源的概念。这些事态发展需要对本项目所解决的有效访问问题进行彻底的重新定义，并需要在几年中并行地进行，并在物理层社区和协议社区中孤立地进行了发展。通过从这两个领域汇总出广泛的专业知识，该项目设想了访问层的无线网络的基本进步。核心挑战是如何尽可能有效地使用“空间”和“时间”的稀缺资源。此外，分布式操作，通道褪色，时变通道条件以及传输机会和决策的快速时间尺度加剧了问题。该项目有可能在中等访问科学方面取得变革性进步。
