Abstract

The embodiment of the application discloses a link establishment method, a device, a base station and a storage medium. The method comprises the steps of carrying out handshake confirmation with a baseband unit according to a first communication rate supported by the radio remote unit and a second communication rate supported by the baseband unit under the condition of power-on or chain breakage, carrying out configuration according to a matching result if the first communication rate is matched with the second communication rate after confirmation, and establishing a communication link with the baseband unit after configuration. According to the embodiment, whether the first communication rate supported by the remote radio unit is matched with the second communication rate supported by the baseband unit or not is confirmed through handshake between the remote radio unit and the baseband unit, blind test is not needed, matching time of the first communication rate and the second communication rate is shortened, and establishment efficiency of a communication link between the two is improved.
