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下一代无线蜂窝网络对更高容量、更高可靠性和无处不在的覆盖范围的指数级需求。拟议的研究计划将集中在创新技术，将推动这一持续的无线革命。建议的研究是基于一个中心的观察，在无线网络中的未来指数增长将需要启用新的合作传输策略，在整个网络中，网络拓扑结构本身的优化，而不是传统的无线链路级技术的改进。未来网络中的基站将部署得更密集，频率将更积极地重复使用，网络拓扑结构将越来越异构，因此有必要对网络设计进行重新思考。在这样的环境中，多用户干扰将成为服务提供的关键瓶颈，使用协作技术管理和减轻干扰将成为中心任务。

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.
