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.

Abstract: Embodiments of the present invention provide a method and apparatus for determining a connection relationship between an antenna feeding port of a base station and an antenna port. The method includes: receiving, via one antenna port, a signal sent by a base station, and acquiring the signal via a Smart Bias-Tee in an antenna and a port of a remote control unit in the antenna, where the antenna port, the Smart Bias-Tee, and the port of the remote control unit are in a one-to-one correspondence; determining, according to the Smart Bias-Tee and the port of the remote control unit that acquire the signal, the antenna port that receives the signal; and sending, to the base station, identification information of the antenna port that receives the signal, and/or identification information of an antenna corresponding to the antenna port. Then accuracy and convenience in determining the connection relationship can be improved.
