摘要： The present disclosure relates to a method performed by a first entity performing high physical layer functions of a base station in a wireless communication system, the method comprising: identifying a fronthaul interface between the first entity and a second entity performing low physical layer functions of the base station; and exchanging a control plane message or a user plane message with the second entity via the fronthaul interface, wherein the low physical layer functions include a digital beamforming, wherein the high physical layer functions include a modulation and a resource element (RE) mapping for a downlink and a demodulation and a RE demapping for an uplink, and wherein the control plane message and the user plane message are identified based on a subtype field of radio over ethernet (ROE).
