The present invention discloses a method, includes: managing a first cell, obtaining resource scheduling information of a neighboring cell of the first cell in a first time interval, and determining an interference level of inter-cell interference of the first cell according to the obtained resource scheduling information; and measuring an inter-cell interference value of the first cell in a second time interval, and storing the measured inter-cell interference value of the first cell in the second time interval by using the interference level as an index, where the interference level is determined according to the resource scheduling information in the first time interval. Based on a stored correlation between an interference level and a real inter-cell interference value obtained by means of measurement, the first base station can quickly and accurately predict a future inter-cell interference value by determining an interference level of inter-cell interference.

Method and device for handling inter-cell interference, control apparatus, and base station

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.
