ConnectionControlUeD2D¶

simple module ConnectionControlUeD2D

D2D-capable variant of the ConnectionControlUe: the leg reports itself D2D-capable when it connects to a base station (if its PHY is), which is where the D2D side of its handovers is handled (ConnectionControlEnbD2D), and a torn-down sidelink bearer’s DRB identity returns to the network-wide sidelink pool (D2dBinder). Selected via ‘connectionControl.typename’ / ‘nrConnectionControl.typename’ by the D2D-capable UE NICs.

Extends¶

Name	Type	Description
ConnectionControlUe	simple module	UE-side component that manages handover decisions and procedures. Receives RSSI measurements from the PHY layer based on broadcast frames, and triggers handover when a better serving cell is detected.

Parameters¶

Name	Type	Default value	Description
dynamicCellAssociation	bool	false
enableHandover	bool	false	Allows handovers in the UE
isNr	bool		Whether this instance is associated with the NR or the LTE stack
macNodeId	int		MacNodeId of the stack leg this controller belongs to (set by the NIC)
sessionType	string		The type of the session the UE requests at connection setup (see LteUe), set by the NIC
handoverLatency	double	50ms	Handover duration
handoverDetachmentTime	double	handoverLatency > 0s ? handoverLatency/2 : 25ms
handoverAttachmentTime	double	handoverLatency > 0s ? handoverLatency-handoverDetachmentTime : handoverDetachmentTime
minRssiDefault	bool	true	Whether minRssi is taken from PhyPisaData instead of the minRssi parameter
minRssi	double	-99.0dB	Configurable minimum threshold RSSI for attaching to an eNB (meaningful only if minRssiDefault==false)
hysteresisFactor	double	10
binderModule	string	“binder”
macModule	string	“^.^.mac”
bearerManagementModule	string	“^.bearerManagement”
handoverPacketHolderModule	string	“^.^.handoverPacketHolder”
feedbackGeneratorModule	string	“^.^.dlFbGen”	TODO or “^.^.nrDlFbGen”
otherConnectionControlModule	string	“”
hasCollector	bool	false	True when node has a collector module (ueCollector/nrUeCollector) for this PHY module
d2dBinderModule	string	“d2dBinder”	The network’s D2dBinder, which holds the D2D state
