The invention provides a method and a device for dynamically determining the polarization mode of a base station transmitting antenna and a space encoding mode in a multiple input multiple output system. Base station multi output system of the first mobile terminal to the jurisdiction of the at least one antenna polarization and a spatial encoding measurement aided multi input signal transmission; after the mobile terminal to the auxiliary measuring signals at the receiver, detection of the quality of the signal generation, signal quality related information, and feedback to the base station after station; relevant information of received signal quality, encoding transmit antenna polarization base station to send the signal when the mobile terminal use and data space is determined according to the above information. Compared with the existing fixed antenna polarization mode switching space coding scheme, the invention can significantly improve the system capacity.
