3GPP 25-series – 3G UTRA(N) Radio Aspects
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 Q4-2024 Plenary Meetings. The new ones are displayed with a single red dotted overline.
a vertical bar on the left means that the full text and graphic content are available online for this TS/TR
