|--------------------------|---------------------------------------------------------------------------------------------------------------|
| `--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 initial frequency offset compensation at the UE. Useful when running over the air and/or without an external clock/time source. |
| `--cont-fo-comp` | Enables the continuous frequency offset (FO) estimation and compensation. Parameter value `1` specifies that the main FO contribution comes from the local oscillator's (LO) accuracy. Parameter value `2` specifies that the main FO contribution comes from Doppler shift. |
| `--cont-fo-comp` | Enables the continuous frequency offset (FO) estimation and compensation. Parameter value `1` specifies that the main FO contribution comes from the local oscillator's (LO) accuracy. Parameter value `2` specifies that the main FO contribution comes from Doppler shift. Parameter value `3` specifies that no measured residual DL FO is considered for UL FO pre-compensation. |
| `--initial-fo` | Sets the known initial frequency offset. Useful especially with large Doppler frequency, e.g. LEO satellite. |
| `--freq-sync-P` | Sets the coefficient for the Proportional part of the PI-controller for the continuous frequency offset compensation. Default value 0.01. |
| `--freq-sync-I` | Sets the coefficient for the Integrating part of the PI-controller for the continuous frequency offset compensation. Default value 0.001. |
