`sudo RFSIMULATOR=127.0.0.1 ./nr-uesoftmodem --do-ra --rfsim --parallel-config PARALLEL_SINGLE_THREAD`
## IF setup with OAI
The -C and -CO flags can be used together at UE side to set custom downlink and uplink FR1 intermediate frequencies for the IF equipment.
In order to run this setup, the following flags are needed at the UE side:
`-C`
`--CO`
and the following parameters must be configured in the RUs section of the gNB configuration file:
`if_freq`
`if_offset`
### Run OAI with custom DL/UL intermediate frequencies
The following example uses DL frequency 2169.080 MHz and UL frequency offset -400 MHz, with a configuration file for band 66 at gNB side.
From the `cmake_targets/ran_build/build` folder:
gNB on machine 1:
`sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band66.tm1.106PRB.usrpx300.conf`
UE on machine 2:
