NeTS-WN: Collaborative Research: Interference Management and Cooperation in Wireless Networks: A Modern View

无线通信区别于有线通信的两个重要特征是：无线链路的时变特性和无线传输的广播特性。这种理解导致了关于无线系统设计的观点的根本转变，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。大多数的技术，存在的实现在当前的无线网络，以处理干扰和合作是特设的。在这个项目中，我们专注于无线链路的广播性质，从成功地处理随时间变化的性质的无线链路的线索：无线通信的真正进步来自于对网络思想的基本和信息理论理解的综合。以（a）获得对如何最佳地管理干扰和实现协作的基本理解，（B）构建捕获最佳干扰管理和协作的性能益处的物理层的抽象，以及（c）识别这样的最佳技术产生超越当前技术的显著改进的场景。 我们设想更广泛的影响，这一研究议程的影响，在下一代无线网络的干扰和合作处理的设计规则。

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.
