2024年随手记第十四篇，超短文一篇将HARQ相关的DCI字段汇总一个表格，方便查看。以前的NR HARQ的文章可参考：
随手记录并汇总了各个DCI中与HARQ相关的字段及长度信息如下表：
![]()
按笔者习惯，随手将各个DCI各个相关字段的规范文本进行汇总，方便以后查用：
除了DCI0-1的其他DCI的NDI都是1bit，描述简单：
New data indicator – 1 bit
而DCI0-1的描述如下：
传统DCI0-0/DCI1-0/DCI1-1 Redundancy version ：![]()
![]()
Table 7.3.1.2.3-1 看上面。7.3.1.2.3-1见下面，
DCI0-0/DCI0-1/DCI1-0/DCI1-1的描述如下，最多16个process：
