  • Method for establishing correspondence between sector of base station and antenna, base station, and antenna
    Patent number: 9699672
    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.
