Abstract
The invention provides a method for IQ data mapping, including the following steps of: mapping IQ data of one or more standards to a CPRI radio frame, wherein, the CPRI radio frame includes multiple multi-frames, and boundaries of the multi-frames are aligned with the header of the CPRI radio frame, and each multi-frame includes K basic frames, and each basic frame includes a plurality of IQ sub-containers, and one IQ sub-container constitutes one time slot, and the number K of the basic frames and bit widths Naxc of the IQ sub-containers included in each multi-frame are identical for different standards, and the length of the CPRI radio frame is 10ms. The invention also provides an IQ data mapping apparatus.
