Name	Type	Description
BackgroundCell	compound module	This module implements a lightweight model for a 4G eNodeB or 5G gNodeB. It is used to generate configurable inter-cell interference in the simulated network. Compared to the eNodeB and gNodeB modules, this module occupies time-frequency resources in both the uplink and downlink bandwidth without simulating the actual transmission or reception of data packets to or from User Equipments (UEs). Therefore, it is significantly more efficient from a simulation speed perspective. To achieve this, it includes a BackgroundTrafficGenerator to customize the level of background traffic to be simulated, a BackgroundChannelModel to configure channel parameters, and a BackgroundScheduler that manages the allocation of time-frequency resources based on the traffic generator. Note that this module can generate interference on only one Component Carrier, as configured in the BackgroundScheduler module. To produce interference across multiple carriers, it is possible to use multiple instances of this module, each configured with the desired carrier frequency.
