Rrc

compound module

RRC (Radio Resource Control) layer for LTE/NR networks.

Contains functional submodules corresponding to RRC procedures:

registration: registers the node with the Binder, sets up the interface
drbTable: the configuration of the node's data radio bearers
bearerManagement: sets up and tears down data radio bearers
handoverController: manages handover decisions and procedures (UE only)

The D2D-specific submodules (d2dModeController, d2dModeSelection) are added by the RrcD2D subtype.

Known subclasses

Name	Type	Description
RrcD2D	compound module	D2D-capable variant of the Rrc layer. It adds the D2D mode controller (which coordinates RLC TX-queue draining across a mode switch) and, on the eNB/gNB side (hasD2DModeSelection==true), the periodic D2D mode selection module. Selected via 'rrc.typename' by the D2D-capable NICs.

Parameters

Name	Type	Default value
interfaceTableModule	string
routingTableModule	string
hasHandoverController	bool	false
hasNrHandoverController	bool	false
