Data transmission method and device

A base station, comprising a processor configured to execute program modules stored on a memory, the program modules comprising:

• a receiving module, which is configured to receive orthogonal in-phase and quadrature (IQ) data from an uplink;
• a sequencing module, which is configured to, according to mapping of the IQ data in a Common Public Radio Interface (CPRI) basic frame, utilize at least one storage unit to sequence the IQ data;
• a combining module, which is configured to combine a control word with the sequenced IQ data to form CPRI data;
• and
• a transmitting module, which is configured to transmit the CPRI data;
• wherein the sequencing module includes:
• a sampling unit, which is configured to sample the IQ data;
• an extracting unit, which is coupled with the sampling unit and configured to, according to the mapping of the IQ data in the CPRI basic frame, respectively extract each bit in the sampled IQ data of one clock cycle;
• a storage unit, which is coupled with the extracting unit and configured to respectively store the each bit in different storage units;
• and an instructing unit, which is coupled with the at least one storage unit and configured to instruct the hardware to read in one clock cycle all bits of the same carrier from the different storage units to form carrier data.
