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

Inheritance diagram

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

Known subclasses

Name	Type	Description
LtePdcpRrcEnb	simple module	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.
LtePdcpRrcUe	simple module	The LtePdcpRrcUe module implements the PDCP/RRC layer for an LTE NIC employed at a User Equipment. It performs header compression on incoming IP datagrams
