Claim Text:
1. A data transmission method, comprising: receiving orthogonal in-phase and quadrature (IQ) data from an uplink; according to mapping of the IQ data in a Common Public Radio Interface (CPRI) basic frame, utilizing at least one storage unit to sequence the IQ data; combining a control word with the sequenced IQ data to form CPRI data, and transmitting the CPRI data; wherein according to the mapping of the IQ data in the CPRI basic frame, utilizing the at least one storage unit to sequence the IQ data comprises: sampling the IQ data; according to the mapping of the IQ data in the CPRI basic frame, respectively extracting each bit in the sampled IQ data of one clock cycle; respectively storing the each bit in different storage units; and instructing hardware to read in one clock cycle all bits of a same carrier from the different storage units to form carrier data.
