摘要：

本文着重针对小区干扰消除技术对系统设计的要求进行了分析，提出了一种基于编码块分割的预定义频率资源块分配方法，以支持对多种带宽业务的小区间干扰消除。另外还提出了一种将小区间干扰协调和干扰消除合并使用的混合方法，可以在适应各种带宽业务的同时，实现系统频谱效率的最大化。

关键词: 小区间干扰, 资源块分配, 小区干扰消除, 小区干扰协调

Abstract:

In this paper, the requirements of inter-cell interference(ICI) cancellation to OFDM system design are investigated. Beyond that, a frequency resource block allocation approach based on coding block segmentation is introduced to adapt to different required bandwidths. Furthermore, a hybrid approach combining ICI cancellation and coordination is proposed to maximize the cell-edge and overall system spectral efficiency.

Key words: ICI, frequency resource block allocation, ICI cancellation, ICI coordination
