摘要： A method for transmitting data streams in a multiple input multiple output (MIMO) system is provided, where each data stream is mapped to multiple layers in an MIMO channel space for transmission, and the method includes: performing inter-layer interleaving for N data streams to obtain N interleaved data streams; mapping the N interleaved data streams respectively to N layers in the MIMO channel space, and transmitting the N interleaved data streams that are mapped to the N layers. By using the method of the present invention, a combined CQI can be used in a better way to improve MIMO transmission performance. Further, an impact of inter-layer interference is canceled by using an interference cancellation technology (for example, an SIC technology) based on the inter-layer interleaving.
