Finally, start the OAI gNB.
|

|
||||
#### WNC R1220
|
||||
|
||||
**Version 1.9.0**
|
||||
|
||||
The OAI configuration file [gnb.sa.band77.273prb.fhi72.4x4-wnc.conf](../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band77.273prb.fhi72.4x4-wnc.conf) corresponds to:
|
||||
|
||||
- TDD pattern `DDDDDDSUUU`, 5ms
|
||||
- Bandwidth 100MHz
|
||||
- 4TX4R
|
||||
|
||||
##### RU configuration
|
||||
|
||||
After switching on or rebooting the RU, you can check the RU PTP status with `show ptp clock` to make sure it's locked and run `show running-config` to check the current configuration.
|
||||
To enable RU transmission, use the `radio enable` command. Then verify the configuration with `show running-config`, which should reflect the enabled state:
|
||||
```
|
||||
radio 1
|
||||
no shutdown
|
||||
```
|
||||
|
||||
The required parameters to configure are:
|
||||
|
||||
1. `center-frequency` → 3849990
|
||||
2. `transmit-power` → 24
|
||||
3. `lna-shutdown` → **disabled**
|
||||
4. `transport-interface` → configure the sub-interface (VLAN ID is defined during sub-interface creation)
|
||||
5. `transport-peer-mac` → must match the DU MAC address
|
||||
6. `phase-compensation` → **enabled**
|
||||
7. `bandwidth` → 100
|
||||
8. `sub-carrier` → 30
|
||||
9. `compress-oran-compliant` → **enabled**
|
||||
|
||||
**Note**
|
||||
* Ensure that the VLAN configuration and MAC addressing are consistent with the DU setup.
|
||||
* The RU must be PTP synchronized before starting the gNB.
|
||||
* After reboot, the RU loads its `startup-config`. To save the current configuration, use `copy running-config startup-config`.
