5G NR RRC IEs: Information Elements List

5g nr rrc information element radio resource 3gpp

This page provides a list of 5G NR RRC IEs (Information Elements), including 5G NR system IEs, UE capability IEs, and other Information Elements (IEs). RRC stands for Radio Resource Control. The IEs serve specific purposes within the 5G NR system.

5G NR RRC Information Elements (IEs)

The 3GPP document TS 38.331 Release 15 contains the definitions and fields of 5G NR specific Information Elements (IEs).
