Part of a BackgroundCell module and is responsible for instantiating a configurable number of background UEs (see BackgroundUe module) and setting up their method for computing the channel status information required by the BackgroundScheduler module.

Usage diagram

The following diagram shows usage relationships between types. Unresolved types are missing from the diagram.

Used in compound modules

Name	Type	Description
BackgroundCell	compound module	Implements a lightweight model for a 4G eNodeB or 5G gNodeB for generating configurable inter-cell interference in the simulated network.
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
numBgUes	int	0
enablePeriodicCqiUpdate	bool	true
useProbabilisticCqi	bool	false
computeAvgInterference	bool	false

Properties
