RRC IE · TS 38.331 v19.4.0 (2026-09) · clause 6.3.2

CellGroupConfig is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.

Definition

The CellGroupConfig IE is used to configure a master cell group (MCG) or secondary cell group (SCG). A cell group comprises of one MAC entity, a set of logical channels with associated RLC entities and of a primary cell (SpCell) and one or more secondary cells (SCells). For an NCR-MT, the CellGroupConfig IE is also used to provide the configuration of side control information for the NCR-Fwd access link.
