The functionality and parameters is the same, enhanced with FS6 mode.
The environment variable “fs6” enables the fs6 mode and decided to be cu
or du from the fs6 variable content.
A example configuration file is: $OPENAIR_DIR/enb.fs6.example.conf
The IP addresses in this file should be updated for each network.
The end line option “--split73” enables the fs6 (also called split 7.3) mode and decided to be cu or du.
Example:
`fs6=cu ./ocp-softmodem -O $OPENAIR_DIR/enb.fs6.example.conf --rfsim --log_config.phy_log_level debug
./ocp-softmodem -O $OPENAIR_DIR/enb.fs6.example.conf --rfsim --log_config.phy_log_level debug --split73 cu:127.0.0.1
