Configuration Reference
OCUDU uses a YAML (.yml) configuration file.
The gNB comes with a number of example configuration files, these can be found in the configs/ folder in the source files.
These configuration file examples provide a basic set-up to get users up and running, users can easily modify these to suit their use-case.
These include sample supplementary configuration files for:
- MIMO with a USRP
- Increasing QAM from 64 to 256
- Specific QOS configurations for voice, video, IMS, live-streaming and buffered video streaming
- Slicing support
OCUDU allows configuration files to be used in concatenation with other configuration files, using the -c flag between each file. For example you might want to use both the n310 and MIMO example configs together as follows:
sudo ./gnb -c gnb_rf_n310_fdd_n3_20mhz.yml -c mimo.yml
Furthermore you may wish to use QAM256 in addition to the above. This can be done as follows:
sudo ./gnb -c gnb_rf_n310_fdd_n3_20mhz.yml -c mimo.yml -c qam256.yml
Note: list-of-structures sections such as cells and qos cannot be merged across files due to CLI11 limitations. The last file to define the section takes effect.

Antenna Configuration
OCUDU supports SISO, codebook-based MIMO, and TX/RX diversity. These options can be configured in the cell_cfg section via the nof_antennas_dl and nof_antennas_ul parameters.
When you configure nof_antennas_dl and nof_antennas_ul, it informs the gNB about the number of antennas available for downlink (DL) and uplink (UL) transmissions, respectively. By default, a
single physical antenna is used for both DL and UL, meaning the values of nof_antennas_dl and nof_antennas_ul are not additive.
As shown above, an example of a MIMO configuration file can be found in the example configuration files provided with OCUDU source files.
