Procedure to run NR nFAPI using RF-Simulator

Bring up another loopback interface

If running for the first time on your computer, or you have restarted your computer, bring up another loopback interface with this command:

sudo ifconfig lo: 127.0.0.2 netmask 255.0.0.0 up

VNF command

sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/rcc.band78.tm1.106PRB.nfapi.conf --nfapi VNF --noS1 --phy-test

PNF command

sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/oaiL1.nfapi.usrpx300.conf --nfapi PNF --rfsim --phy-test --rfsimulator.serveraddr server

UE command

sudo ./nr-uesoftmodem --rfsim --phy-test -d --rfsimulator.serveraddr 127.0.0.1

Procedure to run NR nFAPI using Hardware (tested with USRP x310)

VNF command
