Performs bridging of data-plane packets between PDCP entities of two eNodeBs or gNodeBs when Dual Connectivity is employed. The module directly interfaces with the LteX2Manager to transfer such packets over the X2 interface.

Inheritance diagram

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

Used in compound modules

Name	Type	Description
LteNicEnb	compound module	The LteNicEnb module is a network interface that provides LTE connectivity within an eNodeB. It implements the data and signaling planes of the LTE stack, which includes the PDCP, RLC, MAC, and PHY layers. The parameters and submodules allow customization of the eNodeB's behavior, including whether it supports D2D communication, CoMP (Coordinated MultiPoint), or dual connectivity.
