DcMux

simple module

Dual Connectivity mux: routes split-bearer PDCP PDUs between the local PDCP entities and the DcX2Forwarder, which tunnels them to the peer eNB/gNB over X2.

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.

Parameters

Name	Type	Default value	Description
binderModule	string	"binder"
bearerManagementModule	string	"^.rrc.bearerManagement"

Properties

Name	Value	Description
display	i=block/dispatch

Gates

Name	Direction	Description
dcManagerIn	input
dcManagerOut	output
fromEntity [ ]	input	From a secondary's PDCP relay (UL) or a master leg's remote side (DL out)
toRelayEntity [ ]	output	To a secondary's PDCP relay (DL, PdcpRelayEntity)
toRxEntity [ ]	output	To a master PDCP entity's remote (X2) leg (UL in)
