Method for transmitting multiple system radio service IQ data by general public radio interface

The present invention relates to a technology common public radio interface transmission of wireless service data, discloses a method of transmitting multiple common public radio interface radio service IQ data of the system, so that data can be transmitted CPRI interface system, a plurality of different wireless services. The present invention, according to a common multiple relationship between the CPRI basic frame period and the system cycle, the IQ data of the M system cycles into the N CPRI basic frames for transmission, so that the service data rate and the CPRI interface rate matching, easy to implement frame synchronization; the IQ data of M cycles system basic frame IQ containers filled as uniformly as possible in the N CPRI, various fillers may occur depending on design requirements and other operational mode, such that after the container mapping IQ data as possible to achieve a uniform rate; by the same CPRI interface RE and corresponding division of different IQ data of different standards in the CPRI basic frame IQ containers, a variety of different systems to achieve simultaneous transmission of IQ data on the CPRI interface.
