The LtePdcpRrcEnb module implements the PDCP/RRC layer for an LTE NIC employed at eNodeBs. It performs header compression and maps incoming IP datagrams to different Radio Link Control (RLC) modes. Additionally, it supports Dual Connectivity and Split Bearer functionalities.

Inheritance diagram

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

Known subclasses

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.

Extends

Name	Type	Description
LtePdcpRrcBase	simple module	The LtePdcpRrcBase module implements the functionalities of the Packet Data Convergence Protocol (PDCP). It enables header compression and maps incoming IP packets to different Radio Link Control (RLC) modes. This module dynamically creates LteTxPdcpEntity and LteRxPdcpEntity submodules to handle individual transmission/reception connections
