Time sequence adjustment method and apparatus combining baseband and radio frequency

A time sequence adjustment method and apparatus combining a baseband and a radio frequency. Each adjustment cycle comprises: detecting a reception time sequence and a transmission time sequence of data, and acquiring a reception time sequence offset and a transmission time sequence offset of a baseband unit (BBU), and a reception time sequence offset and a transmission time sequence offset of a remote radio unit (RRU); generating a common public radio interface (CPRI) frame header, and acquiring an offset of an air interface frame header; acquiring a data reception adjustment amount and a data transmission adjustment amount corresponding to baseband processing according to the reception time sequence offset and the transmission time sequence offset of the BBU as well as the offset of the air interface frame header; adjusting a reception frame header and a transmission frame header of baseband processing, and adjusting a data flow of baseband processing; and outputting the CPRI frame header, the reception time sequence offset and the transmission time sequence offset of the RRU, the data reception adjustment amount and the data transmission adjustment amount, and the adjusted data flow.
