The present invention relates to the field of communications. Embodiments of the present invention provide a method for determining a calibration weight coefficient and a base station, which can solve the problem in the prior art that when a large-scale and small-pitch antenna array in a base station is calibrated, the implementation of a coupling disk is complex in a wired coupling manner and a receiving channel in a wireless air-interface coupling manner may fail to work normally due to deep saturation. The specific solution comprises: a base station acquires a first response characteristic of any channel in an antenna array in a normal communication mode, a second response characteristic of the channel in a calibration mode, and a ratio of the first response characteristic to the second response characteristic; acquires, in the calibration mode, a third response characteristic corresponding to the channel when the channel sends a calibration signal to a reference channel, and a fourth response characteristic corresponding to the channel when the reference channel sends a calibration signal to the channel; and acquires a calibration weight coefficient according to the ratio of the channel, the third response characteristic and the fourth response characteristic. The embodiments of the present invention are applied in calibration of an antenna array. |
