The user plane data is transported in the form of IQ data. Several IQ data flows are 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).
Antenna-carrier (AxC):
One antenna-carrier is the amount of digital baseband (IQ) U-plane data necessary for either reception or transmission of only one carrier at one independent antenna element.
Antenna-carrier (AxC) Group:
An AxC Group is an aggregation of NA AxC with the same sample rate, the same sample width, the same destination SAPIQ(RRH), and the same radio frame length. In case of NA=1, an AxC Group is the same as an AxC.
