Title:
ELECTRONIC APPARATUS AND METHOD FOR TRANSMITTING USER PLANE MESSAGE ON FRONTHAUL INTERFACE
Document Type and Number:
WIPO Patent Application WO/2023/239022
Kind Code:
A1
Abstract:
Provided is a method performed by a distributed unit (DU), comprising a step of transmitting, to a radio unit (RU) via a fronthaul interface, a management message including information for indicating a representative extended antenna-carrier (eAxC) port. The method may comprise a step of transmitting, to the RU via the fronthaul interface, a control plane message including section information and section extension information for resource allocation. The section extension information may be used to combine a plurality of user plane (U-plane) messages into one U-plane message in the DU or the RU. The representative eAxC port of the fronthaul interface may be used for transmission or reception of the combined one U-plane message.
