异构无线网络的端到端重配置技术研究

E2R（端到端重配置）技术利用SDR（软件无线电）提供的重配置能力，结合先进的资源管理机制和灵活的空中接口实现技术，实现对异构环境的灵活适应和对异构无线资源的有效利用。本文论述了E2R技术的产生背景和基本概念，对重配置研究中的关键技术（体系结构、资源管理和空中接口实现）进行了系统总结，最后就重配置未来研究的重点提出了一些看法。

Renew of End-to-End Reconfiguration Technology in Heterogeneous Wireless Networks

Based on the reconfigurability provided by the Software Defined Radio （SDR）, the End-to-End Reeonfiguration （E2R） technology aiming at realizing the flexible adaptability of the heterogeneous radio environment is used to implement the effective utilization of radio resources with the help of advanced radio re- sources management mechanisms and flexible air interface. This paper first gives a background introduction of E2R technology and its basic concepts. Then we focus on three key points of the E2R technology, including its architecture, resource management and air interface. Finally, we conclude this paper with some advices on the future study points of reconfiguration.
