LteDlFeedbackGenerator¶

simple module LteDlFeedbackGenerator

This is the Lte Downlink Feedback Generator. It manages periodic and aperiodic channel sensing and feedback transmission.

Usage diagram¶

Used in compound modules¶

Name	Type	Description
LteNicUe	compound module	The LteNicUe module is a network interface that provides LTE connectivity within a UE (User Equipment). It implements the data and signaling planes of the LTE stack, which includes PDCP, RLC, MAC, and PHY layers. The parameters and submodules allow customization of the UE’s behavior.
NrNicUe	compound module	Defines a User Equipment (UE) network interface card that supports both LTE and NR (New Radio) technologies. It extends the LteNicUe module by adding additional submodules and parameters to support NR-specific functionalities. D2D support is added by the NrNicUeD2D subtype.

Used in¶

Name	Type	Description
TestFeedback	network	A test harness for the downlink feedback generator: one LteDlFeedbackGenerator and one FeedbackTester that drives it. The two are not connected; the tester reaches the generator by module reference.

Parameters¶

Name	Type	Default value	Description
isNr	bool	false	True for the NR leg (set by NrNicUe on the nrDlFbGen submodule)
macNodeId	int		MacNodeId of the stack leg this generator belongs to (set by the NIC)
feedbackType	string	“ALLBANDS”	Can be ALLBANDS, PREFERRED, WIDEBAND
rbAllocationType	string	“localized”	Resource allocation type (“distributed” or “localized”)
fbPeriod	int	6tti	Period for Periodic feedback in TTI
fbDelay	int	1tti	Time interval between sensing and transmission in TTI
usePeriodic	bool	true	Whether periodic feedback is used in addition to aperiodic feedback
initialTxMode	string	“SINGLE_ANTENNA_PORT0”	Initial txMode (see LteCommon.h)
binderModule	string	“binder”
phyModule	string	“^.phy”
