3GPP 38-series — Radio Technology beyond LTE
The technical specifications (TS) are displayed in blue, while the reports (TR) are shown in green.
TS that have been discontinued in earlier releases are indicated with a light blue color.
TR in the '9' range that have been stopped are highlighted in light green.
TS or TR with a yellow background indicate those updated at the latest Q3-2024 Plenary Meetings. The new ones are displayed with a single red dotted overline.
