Method and apparatus for configuring shared cell in communication system

A middle node in a communication system, the middle node comprising:

• a transceiver;
• a memory;
• and
• at least one processor electrically connected to the transceiver and the memory,
• wherein the at least one processor is configured to:
• receive a request message for capability information from a controller;
• transmit capability information of the middle node as a response to the request message;
• and
• receive 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.

A method performed by a middle node in a communication system, the method comprising:

• identifying a section type 3 control plane message indicating an uplink packet;
• determining user plane symbol reference timing based on the section type 3 control plane message;
• determining combining timing based on the determined user plane symbol reference timing;
• and
• paging and combining a stored uplink packet based on the determined combining timing.
