Interference Mitigation and Network Topology Optimization for Cooperative Wireless Cellular Systems

智能手机、平板电脑和笔记本电脑的快速和前所未有的增长正在推动对下一代无线蜂窝网络的更大容量、更高可靠性和无处不在的覆盖的指数级需求。拟议的研究计划将重点放在创新技术上，这些技术将为这场持续的无线革命提供动力。提出的研究基于一个中心观察，即未来无线网络的指数增长将需要通过跨网络的新型协作传输策略和网络拓扑本身的优化来实现，而不是通过改进传统的无线链路级技术来实现。未来网络中的基站将变得更加密集，频率将更加积极地被重新利用，并且网络拓扑结构将变得越来越不同，这种网络设计的重新思考是必要的。在这样的环境下，多用户干扰将成为业务提供的关键瓶颈，而使用协作技术管理和缓解干扰将成为一项中心任务。

The rapid and unprecedented growth of smart phones, tablets and laptops is driving an exponential demand for higher capacity, increased reliability and ubiquitous coverage in next-generation wireless cellular networks. The proposed research program will focus on innovative technologies that will power this continuing wireless revolution. The proposed study is based on a central observation that the future exponential growth in wireless networks will need to be enabled by novel cooperative transmission strategies across the network, and by the optimization of network topologies themselves, rather than by improvements of traditional wireless link-level techniques. This re-thinking of network design is necessitated by the fact that base-stations in future networks will become more densely deployed, frequencies more aggressively reused, and the network topologies increasingly heterogeneous. In such an environment, multiuser interference will become a critical bottleneck for service provisioning, and the management and mitigation of interference using cooperative techniques will become a central task.
