> 中文摘要: 在宽带无线网络中,频谱是重要但很稀缺的资源.随着无线网络规模的迅速增长,有限的频谱资源已无法满足日益增长的移动流量.为缓解网络压力、提高频谱资源的利用效率,频谱资源管理机制得到了广泛的关注.首先简述无线通信中频谱资源的基本知识,并分析频谱使用所面临的主要挑战;然后,从传统的静态频谱管理和正在成为主流的动态频谱管理两个方面对宽带无线网络中的频谱资源管理研究进行分类总结和分析评价;最后,从管理架构和关键要素两个层面对频谱资源管理未来研究的发展趋势进行了展望.
Abstract:Radio spectrum is the basic and essential resource in broadband wireless networks, however it is quite scarce. With the growing scale of wireless network, the limited spectrum resource cannot meet the demand of exploding mobile traffic. To alleviate burden of networks and improve resource utilization, much efforts have been devoted to efficient mechanisms of spectrum management. This paper first summarizes the fundamental knowledge of spectrum in wireless communications and the challenges faced by spectrum utilization. It then categorizes and evaluates the existing spectrum resource management methods in broadband wireless networks from the aspects of traditional static management and prevalent dynamic management. Finally, it offers a prospect of future research development concerning frameworks and key issues towards dynamic spectrum management.
