项目摘要
This research project focuses on novel optimization technique for ultra-dense networks. We consider a dense deployment of cellular access-points and/or device-to-device links, where multiple transmit and receive pairs mutually interfere with each other, and propose a novel method for spectrum sharing based on an optimization technique called fractional programming. The proposed method is capable of efficiently finding locally optimal solutions to the coordinated scheduling, beamforming, and power control problem across the entire network. Numerically, the fractional programming solution is iterative in nature, but each iteration step typically involves a closed-form solution and is therefore easy to implement. Optimized coordinated transmission is the key to ensuring spectrally compatible bandwidth sharing in ultra-dense networks. As a concrete application, the proposed research will investigate fractional programming based coordinated scheduling scheme for cellular networks with flexible duplex capability, where simultaneous transmissions in uplink and downlink can significantly improve area spectral efficiency. The proposed research will also apply the fractional programming technique to the optimization of spatial multiplex and nulling in large-scale multiple-antenna systems. The proposed method can also be applied to the optimal scheduling of relay links for interference cancellation in cellular networks. Finally, the proposed research will investigate signaling and channel state acquisition strategies to allow distributed implementation of fractional programming techniques. The wireless industry is undergoing profound transformation in the upcoming Big Data era. The introduction of network intelligence in optimizing and adapting network operations dynamically and in real-time will be a key technological step in meeting the increasing demands in important application areas such as smart home, smart office, smart city, and self-driving cars.
本课题的研究重点是针对超密集网络的新型优化技术。我们考虑了蜂窝接入点和/或设备到设备链路的密集部署,其中多个发送和接收对相互干扰,并提出了一种基于分段规划的优化技术的频谱共享新方法。该方法能够有效地在整个网络中找到协调调度、波束形成和功率控制问题的局部最优解。在数值上,分式规划解本质上是迭代的,但每个迭代步骤通常涉及一个闭合形式的解,因此很容易实现。优化的协调传输是确保超密集网络中频谱兼容的带宽共享的关键。作为一个具体的应用,该研究将研究具有灵活双工能力的蜂窝网络中基于分数规划的协调调度方案,其中上行链路和下行链路的同时传输可以显著提高区域频谱效率。该研究还将把分式规划技术应用于大规模多天线系统中的空间多路复用和归零优化。该方法也可应用于蜂窝网络中干扰消除的中继链路的优化调度。最后,建议的研究将调查信令和信道状态获取策略,以允许分式编程技术的分布式实施。在即将到来的大数据时代,无线行业正在经历深刻的变革。在动态、实时地优化和适配网络运营方面引入网络智能,将是满足智能家居、智能办公、智能城市和自动驾驶汽车等重要应用领域日益增长的需求的关键技术步骤。
