WebThe CPRI protocol is a full duplex serial data stream. In other words there is a transmit fiber and a receive fiber. It is also a synchronous protocol, which means the baseband must establish sync with the remote radio before communication can be established. One CPRI stream can support several IQ data flows to several different radios. WebCPRI transports synchronization, C&M (control and management) and baseband IQ data.

WebCompared to CPRI, there are significant differences in how the IQ data is transferred, packed, and unpacked in the FH interface, since CPRI is based on an option 8 split. The option 8 split splits the network at the RF, so the IQ samples have not undergone any PHY processing (FFT/iFFT). As WebThe control and management plane will be mapped to a single information flow over the CPRI link. User plane data: The user plane data are transported in the form of IQ data. Several IQ data flows will be sent via one physical CPRI link. Each IQ data flow reflects the data of one antenna for one carrier, the so-called antenna-carrier (AxC).
