Abstract: A switch assembly, a switch assembly control method, a controller, and a base station are disclosed, which relate to the wireless communications field. The switch assembly includes: a mechanical normally open switch (102), a movable contact (104), and a controller (106), where the controller (106) is connected to a phase shifter (108) of a remote electrical tilt unit, and the movable contact (104) is arranged to move with a driving rod (1082) of the phase shifter (108); when the movable contact (104) reaches a specified position, the mechanical normally open switch (102) is triggered to close. A prior-art problem that interference is caused to a base station signal because an integrated semiconductor chip radio frequency switch is a nonlinear element and a problem that installation is relatively difficult because a volume of a relay switch is relatively large are resolved.

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.
