摘要

提出了一种分层协作框架，在此框架下采用结合协作预编码的跨层协作传输技术以解决异构网络严重的层间干扰，特别是小区范围扩展区域的干扰问题。所提出的协作传输策略基于OFDMA下行传输系统并支持宏基站和低功率基站在资源块级别的协作传输。仿真结果表明在使用小区范围扩展的异构网络中，基于分层协作框架的协作传输技术在系统吞吐量性能方面优于现有eICIC技术。

Abstract

A cross-tier cooperative transmission strategy with cooperative precoding is used to reduce the intercell inter-ference in heterogeneous network

especially the interference in cell range expansion areas. The proposed cooperative strategy supports the cooperative transmission of Macro BS and low power BS at resource block level based on LTE-Advanced downlink transmission system. Simulation results indicate that the cooperative strategy based on hierar-chical cooperative framework provides more satisfactory system throughput gains compared with non-cooperative scheme and the existing eICIC technology under cell range expansion.
