项目摘要

Two important features distinguish wireless communication from wireline communication: the time-variations of the wireless links and the broadcast property of wireless transmissions.In the past decade, a new fundamental understanding of time-variations from an information theoretic point of view has developed. This understanding has led to radical shifts in points of view regarding wireless system design, not only at the physical layer but also athigher layers. In contrast, the progress in a fundamental understanding of the broadcast nature of wireless links has been far slower. Most of the techniques that exist as implemented in current wireless networks to deal with interference and cooperation are ad hoc.In this project we focus on the broadcast nature of the wireless link by taking a cue from the success in dealing with the time varying nature of the wireless link: true progress in wireless communication comes from a synthesis of a fundamental and information theoretic understanding into networking ideas.We propose to (a) obtain a fundamental understanding of how to optimally manage interference and achieve cooperation, (b) build an abstraction of the physical layer that captures the performance benefits of optimal interference management and cooperation, and (c) identify scenarios in which such optimal techniques yield significant improvement beyondcurrent techniques. We envision the broader impact of this research agenda to influence the design rules by which the interference and cooperation are dealt with in next generation of wireless networks.

无线通信与有线通信的两个重要特征是：无线链路的时变性和无线传输的广播特性。在过去的十年中，从信息论的角度对时变性有了新的基本理解。这种理解导致了无线系统设计观点的根本转变，不仅在物理层，而且在更高层。相比之下，对无线链路广播性质的基本理解的进展要慢得多。当前无线网络中实现的用于处理干扰和协作的大多数技术都是临时的。在这个项目中，我们通过从成功处理无线链路的时变性质中获得线索，重点关注无线链路的广播性质。无线链路：无线通信的真正进步来自于将基础理论和信息理论理解综合到网络思想中。我们建议（a）获得对如何最佳管理干扰和实现合作的基本理解，（b）建立一个抽象捕获最佳性能优势的物理层干扰管理和合作，以及 (c) 确定此类最佳技术比当前技术产生显着改进的场景。我们预计该研究议程将产生更广泛的影响，以影响下一代无线网络中处理干扰和合作的设计规则。
