Coordinated beamforming and power optimization for interference mitigation in wireless backhaul networks

无线网络的快速发展、巨大的数据使用量以及可用无线电资源的稀缺性，对未来无线系统的空中接口设计提出了严格的要求。提出的研究设想了一种新的无线网络架构，其中密集部署具有无线回程的小型基站，以便为移动用户提供更好的覆盖和更高的吞吐量。然而，基站部署密度的增加也带来了一系列新的设计挑战，特别是在回程中提供高速无线数据以及控制和减轻无线干扰方面。本提案的目标是开发无线回程收发器的复杂优化方法。特别地，提出的研究旨在开发新颖实用的波束形成和功率优化方法，跨多个小区进行协调，并专门开发以最小化甚至消除干扰，作为实现未来无线回程网络更高数据容量和提高系统可靠性的手段。波束形成和功率优化算法的可行性和实用性将是本文研究的重点。

The rapid pace of growth of wireless networks, their enormous data usage, and the scarcity of the available radio resources are placing stringent demands on the design of air interface for future wireless systems. The proposed research envisions a novel wireless network architecture in which compact mini-base-stations with wireless backhaul are densely deployed in order to provide better coverage and higher throughput to mobile subscribers. This increase in base-station deployment density, however, also brings in a novel set of design challenges, particularly in terms of the provisioning of high-speed wireless data in the backhaul and the control and mitigation of wireless interference. The goal of this proposal is to develop sophisticated optimization methods for wireless backhaul transceivers. In particular, the proposed research aims to develop novel and practical beamforming and power optimization methods, coordinated across multiple cells and specifically developed to minimize or even to eliminate interference, as a means to achieve higher data capacity and increased system reliability for future wireless backhaul networks. The feasibility and practicality of the beamforming and power optimization algorithms will be a main focus of the proposed research.
