Autonomous infrastructure wireless networks based on LTE femtocells

目前，4G无线网络作为一种应对日益增长的宽带无线服务需求的手段，受到了极大的关注。国际电信联盟目前正在进行一项进程，以指定被称为IMT-Advanced的下一代无线网络。这些网络将采用更新的技术，例如MIMO传输和来自多个协调基站/接入点的信号传输。与此同时，人们对部署被称为毫微微小区的非常小的小区产生了极大的兴趣，这最终提供了实现真正高容量网络的最终途径。多伦多大学的无线实验室是自主基础设施无线网络的最初倡导者，该网络推广了早于毫微微蜂窝的毫微微蜂窝版本。无线运营商联盟3GPP提交的LTE-Advanced是IMT-Advanced的主要候选技术之一。然而，在3GPP提案中引入自主概念的研究相对滞后，许多研究还有待于回答基本问题和确定主要算法。这项提议的目标是专注于不断发展的LTE空中接口，并在网络的协调、多点和自主方面做出贡献。空中接口的自动特性将允许网络运营商和用户的混合大大简化部署，从而为网络基础设施的有机增长铺平道路，并最终成为为大量用户实现真正大数据速率的唯一途径。

There is currently a great interest in 4G wireless networks as a means to cope with the vastly increasing demands for broadband wireless services. The ITU is currently undertaking a process to specify the next generation wireless networks known as IMT-Advanced. These networks will incorporate newer technologies such as MIMO transmission and the transmission of signals from multiple coordinated base stations/access points. At the same time there has been a great interest in the deployment of very small cells known as femtocells which in the end provides the ultimate path to achieve truly high capacity networks. The wireless lab at the University of Toronto was the original proponent of autonomous infrastructure wireless networks which generalized version of femtocells which preeceded femtocells. One of the major technology candidates for IMT-Advanced is LTE-Advanced which has been submitted by the wireless operator alliance - 3GPP. However the introduction of autonomous concepts into the 3GPP proposals has lagged and much research remains to answer basic questions and determine the main algorithms. The goal of this proposal is to focus on the evolving LTE air interface and make contributions on coordinated multipoint and autonomic aspects of the network. The autonmoic features of the air interface will allow greatly simplified deployment by a mixture of network operators and users thus paving the way for organic growth of the network infrastructure and ultimately the only path to achieve truly large data rates for a large number of users.
