Key 3GPP Specifications

The 50 most important 3GPP specifications, selected based on how frequently they are referenced by other documents.

Methodology: Ranking is derived from citation analysis — how often each specification is referenced by other 3GPP documents. Specifications with a paired LTE/NR counterpart (e.g. TS 38.331 / TS 36.331) are flagged with an Evolution badge, indicating AI-generated cross-release analysis is available.
