cedures include UE context setup, UE context release request (gNB-DU/gNB-CU initiated), UE context modification (gNB-CU/gNB-DU initiated), and UE mobility command. The F1-C RRC message transfer procedures include initial uplink RRC message transfer as well as UL/DL RRC message transfer. The F1 control plane fur- ther includes system information procedure and paging procedures [28]. The error indication function is used by the gNB-DU or gNB-CU to indicate occurrence of an error. The reset A gNB UE context is a block of information in the gNB associated with an active user equipment. The block of information contains the necessary information in order to provide NG-RAN services to the active user equipment. The gNB user equipment context is established when the transition to active state for a user equipment is completed or in target gNB after completion of handover resource allocation during handover preparation, where in each case the user equipment state information, security information, user equipment capability information, and the identities of the user equipment-associated logical NG connection are stored in the gNB user equipment context. 5G Network Architecture 121 function is used to initialize the peer entity after node setup and after a failure event. This procedure can be used by both the gNB-DU and gNB-CU. The F1 setup function, initiated by gNB-DU, allows exchange of application-level data between gNB-DU and gNB-CU while ensuring proper interoperability over the F1 interface. The gNB-CU and gNB-DU configuration update functions facilitate updating application-level configuration data between gNB-CU and gNB-DU to properly interoperate over the F1 interface, and activate or deactivate the cells. Scheduling of broadcast system information is performed in the gNB-DU. The gNB-DU is responsible for encoding of NR-MIB (master information block portion of NR system information). In case broadcast of RMSI (remaining system informa- tion) or other SI messages is needed, the gNB-DU will be responsible for enco
