Abstract: Embodiments of this application provide a communication method and a communication apparatus. 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. Based on the method, in embodiments of this application, codeword-to-layer mapping can be dynamically adjusted and/or indicated. 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.
