Abstract: The present invention discloses a method and an apparatus for channel calibration among multiple RRUs, and pertains to the field of communications technologies. The method includes self-calibrating two RRUs to obtain two self-calibration coefficient, exchanging calibration sequences between the two RRUs through an air interface, returning, by one RRU, the calibration sequence received from another RRU to the another RRU in the air interface, and acquiring a calibration coefficient of the another RRU according to the calibration sequences and the self-calibration coefficients.
