transmitting, to an O-RAN radio unit (O-RU) through a fronthaul interface, one or more control plane (C-plane) messages; and
receiving, from the O-RU through the fronthaul interface, an acknowledgement (ACK)/negative-acknowledgement (NACK) feedback message for the one or more C-plane messages,
wherein each C-plane message of the one or more C-plane messages includes section extension information for requesting ACK/NACK feedback,
wherein the section extension information includes a request identifier (ID) used to identify a section description for which the ACK/NACK feedback is requested, and
wherein the ACK/NACK feedback message includes at least one of ACK information for indicating a request ID of a correctly decoded section description or NACK information for indicating a request ID of an incorrectly decoded section description.
