CALIBRATION COUPLEING UNIT, CCU, AND A METHOD THEREIN FOR ENABLING CALIBRATION OF BASE STATION |
摘要 |
<p>A Calibration Coupling Unit, CCU, and a method therein for enabling calibration of a Base Station are provided.The CCU comprises an Antenna Interface Standards Group, AISG, interface and the CCU is connected to the Base Station by means of radio branch feeder cables carrying uplink and downlink transmissions to/from the Base Station. The Base Station comprises a Radio Unit, RU, and a Base Band Unit, BBU, and the CCU is further connectable to an antenna array comprising antenna elements. The method in the CCU comprises receiving (110) at least one calibration signal from the RU on at least one radio branch feeder cable of the CCU; and converting (130) the calibration signal to a receiving frequency band of the RU. The method further comprises providing (140) the converted signal to the RU via at least one of the radio branch feeder cables, thereby enabling calibration of the Base Station.</p> |
