@@ -137,6 +137,7 @@ Here are some useful command line options for the NR UE:
|--------------------------|---------------------------------------------------------------------------------------------------------------|
| `--ue-scan-carrier` | Scan for cells in current bandwidth. This option can be used if the SSB position of the gNB is unknown. If multiple cells are detected, the UE will try to connect to the first cell. By default, this option is disabled and the UE attempts to only decode SSB given by `--ssb`. |
| `--ue-fo-compensation` | Enables the frequency offset compensation at the UE. Useful when running over the air and/or without an external clock/time source. |
| `--initial-fo` | Sets the known initial frequency offset. Useful especially with large Doppler frequency, e.g. LEO satellite. |
| `--usrp-args` | Equivalent to the `sdr_addrs` field in the gNB config file. Used to identify the USRP and set some basic parameters (like the clock source). |
| `--clock-source` | Sets the clock source (internal or external). |
| `--time-source` | Sets the time source (internal or external). |
