Abstract: One embodiment is directed to a system comprising a distributed unit (DU) and a plurality of remote units (RUs) to wirelessly transmit and receive radio frequency signals to and from the user equipment using a wireless interface. The DU and RUs are communicatively coupled to each other over a fronthaul and are configured to communicate over the fronthaul using an O-RAN fronthaul interface. The DU and RUs are configured to communicate O-RAN control-plane and user-plane messages that include a new O-RAN section extension for use in communicating different section data to different RUs. Other embodiments are disclosed.
