Overview
3GPP groups its specification work into Releases (Rel-15, Rel-16, and so on), and each Release is made up of Work Items, the individual pieces of technical work that produce or update specifications. The TR 21.9xx series below are the official per-Release summary reports, each describing the Work Items completed in that Release and their main achievements. This table links to those summaries so you can see, at Release level, what 3GPP delivered.
The Status / timeframe column below is indicative only.
