 ### Run OAI in sa mode
 
+At the gNB the --sa flag does the following
+- it reads the RRC configuration from the configuration file
+- it encodes the RRCConfiguration and the RBconfig message and stores them in the binary files rbconfig.raw and reconfig.raw
+- the RRC encodes SIB1 according the configuration file and transmits it through PDSCH
