1. A beam information indication method, the method comprising:
obtaining, by a first communication apparatus, a first offset, wherein the first offset indicates an offset of domain information of a plurality of beams relative to reference domain information of the plurality of beams, wherein the domain information comprises frequency domain information and polarization domain information, wherein each beam of the plurality of beams corresponds to a different color in color multiplexing information, and wherein each color corresponds to a different combination of a frequency mode and a polarization mode; and
updating, by the first communication apparatus, the domain information of the plurality of beams based on the reference domain information of the plurality of beams and the first offset.
