Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Facing the development requirement of the 5G (the 5th generation, fifth generation mobile communication technology) network, the 5G mobile communication Base station is to be reconfigured from the existing BBU (baseband processing module) -RRU (Remote Radio Unit) architecture to CU (Central Unit) -DU (Distributed Unit) -RRU architecture, the original BBU function is to be reconfigured to CU and DU two functional entities, wherein the CU device mainly includes a non-real-time wireless upper layer protocol stack function and also supports the deployment of part of core network function sinking and edge application services, the DU device mainly handles the layer function of physical layer functionality and real-time requirement, the interface between the device and the RRU is a fronthaul interface, in the 4G era, the interface generally adopts the CPRI standard to replace the conventional coaxial cable connection, the CPRI is an interface standard based on direct connection cable, the method realizes data multiplexing in a TDM mode, needs exclusive transmission bandwidth, defines three types of data streams of user, control, management and synchronization, wherein the data stream of a user plane transmits quantized IQ transceiving signals of an RRU antenna. The user plane data bandwidth of the CPRI is proportional to the sampling frequency (bandwidth) and the number of ports. In order to meet 5G requirements, CPRI organizations promulgated the eccri protocol in 2017. Unlike CPRI, eCPRI is a packet-based interface standard, does not specify a network implementation form, and can be implemented by any network (e.g., ethernet/IP/UDP/OTN). The protocol only specifies the user plane data and some real-time control messages, such as frame formats of remote memory read-write, delay measurement and the like, does not specify the implementation of control management and synchronization, and recommends the implementation of the existing mature scheme based on the network, such as the synchronization based on PTP and SyncE in the Ethernet. In order to reduce bandwidth overhead, eCPRI provides references of several division forms based on a BBU-RRU division mode defined by 3GPP, and partial or all physical layer functions are divided into RRUs to be realized, so that data transmitted between the BBU and the RRU are changed into modulation symbols (IID), coding bit sequences (ID) and even original data bits (D) from IQ signals on antennas, and thus, the communication bandwidth between the BBU and the RRU is remarkably reduced.
In the current eCPRI protocol, a data format for verifying the forwarding interface is not specified explicitly, and the method is not suitable for wide industry clients. In future industry customers, or the data sensitivity is high, the requirement on the accuracy is high; or the deployment condition is relatively bad, and packet loss is easy to occur in the transmission process.
