面向5G新空口的码本设计标准化研究
|
摘要
R15阶段,5G新空口码本设计基本延用R13、R14的码本设计思路,但为了满足多种传输场景,R15的码本设计更为精细,同时引入了多天线阵面码本、混合波束赋形等新特性,为后续码本技术增强做好了准备。根据目前标准进展,总结了R15阶段5G新空口码本技术的标准化内容,讨论了R16阶段码本增强技术,最后给出了各种码本方案优缺点的对比及应用分析。
In the stage of Rel-15 version, the codebook design in 5G New Radio(NR) basically inherits the codebook design idea in Rel-13 and Rel-14. However, in order to meet the multiple types of transmission scenarios, more fine codebook design introduces multi-antenna array codebook and hybrid beamforming to enhance the subsequent codebook technique. Based on current standardization progress, the standardization contents of 5G NR codebook design in Rel-15 version are summarized in this paper, and the codebook enhancement in Rel-16 version is discussed. Finally, the comparison of advantages and disadvantages of different codebook schemes, as well as the application analysis are presented.
