摘要
随着3G移动通信系统逐步成熟,3GPP已经开始了对其长期演进(LTE)系统的研究和标准化工作。由于使用了新的物理层技术,使得小区间干扰抑制成为一个热点问题。针对该问题,介绍了目前小区间干扰协调/躲避研究方面的现状,对几种具有代表性的方案进行了研究,最后对各方案进行了系统级计算机仿真分析。
With the mature of 3G mobile systems, 3GPP has been launched study and standardization work of its long term evolution system. Due to the new physical layer technology adopted,intercell interference becomes an important issue. Various technologies of interference coordination and avoidance are studied. Some representative methods are analyzed. The performance of these methods is showed by system level simulation.
