摘要 简单介绍了LTE-Advanced的关键技术之一——协作多点传输技术,通过分析该技术,指出了在下行反馈方面存在的反馈开销巨大的问题。通过对比现有的方案,并在现有方案基础上提出了新的反馈方案,从而在减小反馈开销方面得到很大提升。 This paper introduces the technology of Coordinated Multiple Points Transmission; it is one of the key technologies in LTE-Advanced. Based on the analysis of this technology,the paper points out the existing problems in the aspect of feedback overhead in downlink and compares with the existing schemes. Based on the existing schemes,this paper puts forward the new feedback scheme. The new scheme can effectively reduce the feedback overhead.
