The NRPdcpRrcEnb module implements the PDCP/RRC layer for a NR NIC utilized at a Base Station. It extends the LtePdcpRrcEnbD2D module to enable Dual Connectivity and Split Bearer functionalities at the eNodeB module.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Extends

Name	Type	Description
LtePdcpRrcEnbD2D	simple module	The LtePdcpRrcEnbD2D module implements the PDCP/RRC layer for a LTE NIC employed at eNodeBs, providing support for D2D (Device-to-Device) communications. This module extends the basic LtePdcpRrcEnb by adding functionality for managing D2D-capable user equipment, specifically for buffering packets during D2D mode switching operations.
