Electronic device and method for transmitting user place message in fronthaul interface

A method performed by a radio unit (RU), the method comprising:

• receiving a management message including information for indicating a representative extended antenna-carrier (eAxC) port from a distributed unit (DU) through a fronthaul interface;
• and
• receiving a control plane (C-plane) message including section information and section extension information for resource allocation from the DU through the fronthaul interface,
• wherein the section extension information is used to combine a plurality of user plane (U-plane) messages into one U-plane message in the DU or the RU, and
• wherein the representative eAxC port of the fronthaul interface is used for transmitting or receiving of the combined one U-plane message.

An electronic device of a distributed unit (DU), the electronic device comprising:

• at least one transceiver;
• and
• at least one processor coupled to the at least one transceiver,
• wherein the at least one processor is configured to:
• control the at least one transceiver to transmit a management message including information for indicating a representative extended antenna-carrier (eAxC) port to a radio unit (RU) through a fronthaul interface, and
• control the at least one transceiver to transmit a control plane message including section information and section extension information for resource allocation to the RU through the fronthaul interface,
• wherein the section extension information is used to combine a plurality of user plane (U-plane) messages into one U-plane message in the DU or the RU, and
• wherein the representative eAxC port of the fronthaul interface is used for transmitting or receiving of the combined one U-plane message.
