Provided are a method and device for reciprocity correction between base stations, relating to the field of communications. The method comprises the steps of: obtaining by calculation, by each base station, a pre-coding vector corresponding to a selected sub-carrier in the present base station (101); sending, by each base station through the selected sub-carrier in the present base station, downlink user-specific reference signals which are orthogonal to each other between cells corresponding to each base station to a user equipment (UE) (102); obtaining, by each base station, inter-base station correction compensation coefficients of the selected sub-carrier in the present base station (103); and adjusting, by each base station, a self-correction matrix of the selected sub-carrier according to the inter-base station correction compensation coefficients of the selected sub-carrier in the present base station (104). By means of the embodiments of the present invention, the accuracy of reciprocity correction between base stations may be improved. |
