Abstract: A method performed by a middle node in a communication system includes: receiving a request message for capability information from a controller, transmitting capability information of the middle node as a response to the request message; and receiving timing information corresponding to multiple subcarrier spacings (SCSs) from the controller based on the capability information of the middle node.
Abstract: According to one aspect of the technical idea of the present disclosure, a method of operating a node device in an open radio access network (O-RAN) is disclosed, including receiving messages related to a user-plane from at least one south-node device, and determining combining operation timing of the messages in an extended antenna-carrier (eAxC) unit, based on the messages.

Abstract: A method performed by a middle node in a communication system includes: receiving a request message for capability information from a controller; transmitting capability information of the middle node as a response to the request message; and receiving configuration information for an extended antenna carrier (eAxC)_identifier (ID) group supporting Section Extension 10 based on the capability information of the middle node from the controller.
