A macro-diversity switching method based on several users MIMO is provided. Several base stations are in the service of the macro-diversity switching area. By combined-pre-coding the modulated signal to be transmitted, the several base stations transmit the pre-coded signal to several mobile stations with the same time-frequency resource. The signal to be transmitted is transmitted to several mobile stations located in the macro-diversity switching area. Because the pre-coding technique is used, so each mobile station will not bring interfere to other mobile stations, or interfere brought by each mobile station to other stations is small. Because the several base stations in the service of the same macro-diversity switching area are in the service of several mobile stations with the same time-frequency resource at the same time, so the system capability of the macro-diversity switching area is enhanced greatly.
