NED File simulations/nr/networks/SingleCell_withSecondaryGnb.ned

Name	Type	Description
SingleCell_withSecondaryGnb	network	An EN-DC topology: an eNodeB master paired over X2 with a gNodeB secondary. The eNodeB is the only node with a core-network link -- an EPC PgwStandard facing a router and a server -- so all data-plane traffic enters there, and the gNodeB contributes its radio leg alone. numUe NrUe terminals attach to both, and numBgCells BackgroundCell cells can be added as interferers.
