Abstract: Embodiments of the present application relate to a matching method. The method includes: selecting, by a base station, a remote electrical tilt unit and sending instruction information to a signal transmitter, where the instruction information is used to instruct the signal transmitter to connect to an antenna radio frequency port corresponding to the remote electrical tilt unit and enable the signal generator to generate a signal. The method also includes receiving, by the base station, the signal when the signal reaches the antenna radio frequency port through a signal coupling unit and is sent by using the antenna radio frequency port. The method also includes selecting, by the base station, a target sector according to a background noise value of each base-station radio frequency port.

Abstract: The present disclosure provides a method for establishing a correspondence between a sector of a base station and an antenna, a base station, and an antenna. The base station (or the antenna) generates a modulation signal, and a radio frequency port corresponding to the antenna (or the base station) can receive the modulation signal. Then, the base station determines that there is a correspondence between a radio frequency port that is on the base station side and that sends the modulation signal and a radio frequency port that is on the antenna side and that receives the modulation signal. Therefore, the base station establishes a correspondence between a sector and the antenna, which is highly efficient and highly accurate in comparison with a manual recording manner.
