Abstract

The invention discloses a device, a system and a method for sharing an antenna feeder. In the embodiment of the invention, a base station is provided with a frequency selection unit covering the receiving and transmitting frequencies of other base stations, and a corresponding antenna feeder shared interface to achieve the sharing of the antenna feeder without an additional antenna feeder shared cell, thus feeder lines are saved, and the construction difficulty is reduced.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna feeder sharing device, system and method. Background technique [0002] With the development of wireless communication, wireless spectrum resources are becoming more and more tense, and more and more frequency spectrums are used for wireless communication, and there is bound to be a situation of coexistence of multiple frequency bands. However, due to the lack of space resources, in order to improve the utilization efficiency of antenna feeders and reduce costs, multiple base stations are usually used to share a set of antenna feeder systems. This requires antenna feeder sharing between the antenna feeder system and the antenna feeder interfaces of multiple base stations Unit, referred to as ASU (AntennaSharing Unit). ASU combines the transmitted signals of multiple base stations and then outputs them to the antenna feeder system, or separates multiple signal...
