Abstract: Embodiments of this application provide an antenna calibration method and apparatus. In the method, for a first antenna unit and a second antenna unit, candidate phase compensation coefficients used for antenna calibration are determined based on channel responses indicating that a first calibration signal sent by the first antenna unit is received by the first antenna unit and the second antenna unit and channel responses indicating that a second calibration signal sent by the second antenna unit is received by the first antenna unit and the second antenna unit; and a phase compensation coefficient is selected from the candidate phase compensation coefficients based on measurement on an uplink signal sent by user equipment.
