IMT-Advanced评估场景及信道模型

IMT—Advanced是ITU-R对IMT-2000以后的下一代移动通信技术的新定义．期望其能在现有的IMT-2000的长期演进技术的基础之上，能够进一步提升无线传输系统的数据业务提供能力，包括更高的带宽、峰值和平均频谱效率，更好的小区边缘频谱效率和更低的业务延迟等。为了推动各标准化组织开展相关的研究和标准化工作，ITU—R制定了详细的最小性能技术指标及其评估方法。本文介绍了IMT—Advanced的评估场景及其信道模型。

IMT-Advanced Evaluation Scenario and Channel Model

As the further evolution of ITU-R IMT-2000, IMT-Advanced is expected to improve the capability to provide wireless data service, including higher bandwidth, higher peak data rate and higher average spectrum efficiency, higher cell edge spectrum efficiency and lower latency. To facilitate the work of IMT-Advanced in ITU-R, WP5D has defined the minimum performance requirements and the corresponding evaluation methodology. This paper introduces the evaluation scenarios and the corresponding channelmodel.
