功能介绍 发布最新移动通信运营态势，5G通信标准规范和技术研究成果，业内专家观点和产业观察。
大家看5G相关规范的时候有没有被各种缩写所困扰？一些图书中没有提供缩写表，是否大家为此而头痛？
为此，小编特意把5G NR的一些重要规范中的Abbreviation部分翻译了出来。包括TS38.101，TS38.104，TS38.211，TS38.212，TS38.213、TS38.214以及TS38.300，供大家参考。
下表中共包含156个，以字母顺序排列。需要说明的是，一些名词如PRG在不同规范中有不同的全称，比如PRG(一作Physical resource block group(TS38.214缩写表)，一作Precoding Resource block Group)， 本文根据TS38.214正文中内容保留Precoding Resource block Group。此外，还有一些写法的差异，比如PTRS和PT-RS是通用的，本文对二者都予以保留。
