Configuration Reference

The srsRAN Project gNB application uses a YAML (.yml) configuration file.

The gNB comes with a number of example configuration files, these can be found in srsRAN_Project/configs/ in the source code:

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.

More example configuration files for various use cases can be found here. 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

These are intended to be used in conjunction with other configuration files, for example you might run the MIMO example 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
