<p>Embodiments of the present invention provide a method and base station for transmitting a signal. The method includes: generating n pieces of coordination information respectively corresponding to n coordinated base stations, where each piece of coordination information includes a cell identity CELL ID of a serving base station, a scrambling identity SCID, of a user equipment UE, and information about a port number used by a corresponding coordinated base station, and the port number used by the coordinated base station is different from a port number used by the serving base station, and n is a positive integer; and respectively sending the n pieces of coordination information to the n coordinated base stations. The embodiments of the present invention, by exchanging coordination information between a serving base station and a coordinated base station, enable the coordinated base station to transmit a signal according to the coordination information of the serving base station, and require no transmit antenna calibration between RRUs of different cells, thereby avoiding the impact of transmit antenna calibration on CoMP JT performance.</p> |
