List of 5G NR RRC IEs | 5G NR RRC Information Elements

This page covers list of 5G NR RRC IEs (Information Elements). It includes 5G NR system IEs,UE capability IEs and other Information Elements (IEs).

The RRC stands for Radio Resource Control. The IEs are used for specific purposes in the system.

5G NR RRC Information Elements (IEs)

Following 3GPP published document TS 38.331 Release 15 covers definitions and fields of 5G NR specific Information Elements (IEs).
