The method includes: A first communication apparatus receives a first indication parameter. There is a correspondence between the first indication parameter and first codeword-to-layer mapping. The first communication apparatus determines the first codeword-to-layer mapping based on the first indication parameter.

For example, a terminal device may use different codeword-to-layer mapping at different moments. For another example, different terminal devices may use different codeword-to-layer mapping at a same moment. Therefore, in a scenario in which a performance difference between streams of the terminal devices is large or a scenario in which a performance difference between streams at different moments is large, the different codeword-to-layer mapping may be used, and transmission of more streams may also be supported, to meet a requirement of a gradually enlarged scale of transmit antennas and receive antennas of a multiple-input multiple-output system.＜img id="iaf01" file="imgaf001.tif" wi="77" he="50" img-content="drawing" img-format="tif" /＞
