Abstract

The invention discloses a CPRI-based data transmission method, apparatus and device, and a storage medium. The method comprises the steps of receiving user plane data, control plane data, management plane data and synchronous clock data; mapping the user plane data, the control plane data, the management plane data and the synchronous clock data into a CPRI frame; and sending the CPRI frame to an O-RAN radio frequency unit through a first serial deserializer, so that the O-RAN radio frequency unit receives the CPRI frame through a second serial deserializer, analyzes the CPRI frame, analyzes user plane data, control plane data, management plane data and synchronization plane data from the CPRI frame, and sends the user plane data, the control plane data, the management plane data and the synchronization plane data to the O-RAN radio frequency unit. And sending the user plane data, the control plane data, the management plane data and the synchronization plane data to a second physical layer for processing. According to the invention, the technical problem that the data transmission process of the existing 5G technology forward transmission interface is complex is solved.

Description

technical field [0001] The embodiment of the present application relates to the 5G field, and in particular to a CPRI-based data transmission method, device, device, and storage medium. Background technique [0002] At present, with the further evolution of wireless technology, 5G technology has gradually entered daily life. With the large-scale use of 5G technology, the architecture of wireless network access networks has also undergone major changes. For example, for 4G technology, a 4G base station is composed of a baseband processing unit (Baseband Unit, BBU), a remote radio unit (RRU), a feeder, and an antenna. The fronthaul interface is the interface between the BBU and the RRU. The fronthaul interface Comply with the Common Public Radio Interface (CPRI) protocol. For 5G technology, the BBU function of the base station is reconstructed into a central unit (CentralUnit, CU) and a distributed unit (Distributed Unit, DU), and the RRU and the antenna are combined into an ...
