1. A method, comprising:
generating indication information, wherein the indication information indicates KNZ−v non-zero weighting coefficients, the KNZ−v non-zero weighting coefficients belong to KNZ non-zero weighting coefficients, v is a quantity of transport layers, and the KNZ non-zero weighting coefficients are for constructing a precoding matrix, and wherein:
when a first preset condition is met, the indication information further indicates that a group 1 comprises ┌KNZ/2┐−v first-type parameters, and wherein the first preset condition comprises the following condition: ┌KNZ/2┐−v>0; or
when a second preset condition is met, the indication information further indicates that a group 2 comprises KNZ−v first-type parameters, wherein the second preset condition comprises the following condition: ┌KNZ/2┐−v≤0; and
sending the indication information.
