1. A computer-readable non-transitory storage medium that stores instructions for execution by one or more processors of a next generation NodeB (gNB), the one or more processors to configure the gNB to, when the instructions are executed:
initiate, by one of a central unit control plane (gNB-CU-CP) and a central unit user plane (gNB-CU-UP), a first stream control transmission protocol (SCTP) connection between the gNB-CU-CP and gNB-CU-UP; and
subsequently initiate an E1 Setup procedure to set up an E1 interface between the gNB-CU-CP and the gNB-CU-UP,
wherein initiation of the E1 Setup procedure is performed by the gNB-CU-CP when the gNB-CU-CP initiated the first SCTP connection, and
wherein initiation of the E1 Setup procedure is performed by the gNB-CU-UP when the gNB-CU-UP initiated the first SCTP connection.
