Abstract
A method, equipment and system for implementing coordinated multi-point transmission are provided for resolving the problem that there exists phase noise in the signals received by a User Equipment (UE) end in coordinated multi-point transmission. The method for implementing coordinated multi-point transmission includes: obtaining phase differences between the current service cell and other coordinated cells by calculating channel cross-covariance matrixes between the current service cell and other coordinated cells in a coordinated multi-point transmission system (); feeding back the phase differences corresponding to the base stations of said other coordinated cells respectively to the base stations of said other coordinated cells, in order to implement phase compensation (); receiving the signals transmitted after the phase compensation by base stations of all the coordinated cells (). The method, terminal and system provided by the embodiments of the present invention are applicable to the coordinated communication in various wireless networks.
