¿µ¹®³»¿ë¿ä¾à The standard describes fronthaul requirements, specifying two classes (Class 1 -CPRI (Common Public Radio Interface), Class 2 - eCPRI (Enhanced CPRI)) of the requirements that depend on the BS (Base Station) functional decomposition, and the synchronization (time, frequency) requirements that apply to both classes. The standard describes how the operation of bridges and bridged networks affects the quality of service provided by the fronthaul bridged network, providing details to assist in the calculation of latency, the selection of network synchronization methods, and the potential impact of the use of flow control and Energy Efficient Ethernet).
And the standard specifies two fronthaul profiles that support the construction of bridged networks meeting fronthaul requirements and describes the applicability of the network synchronization methods to the synchronization requirements.
