1. A parameter configuration method, comprising:
receiving an indication of a first mapping relationship, wherein the first mapping relationship is a mapping relationship in a preconfigured first mapping relationship group, the preconfigured first mapping relationship group comprises the first mapping relationship, and the first mapping relationship indicates a pair of a first value indicating a reporting quantity L0 of spatial domain vectors and a second value indicating a reporting quantity M0 of frequency domain vectors;
determining the reporting quantity L0 of spatial domain vectors and the reporting quantity M0 of frequency domain vectors based on the first mapping relationship, wherein both L0 and M0 are positive integers; and
determining, based on the reporting quantity L0 of spatial domain vectors and the reporting quantity M0 of frequency domain vectors, a quantity K0 of space-frequency vector pairs for constructing a precoding vector, wherein:
K0≤2L0×M0, and K0 is a positive integer;
2L0×M0 represents a sum of quantities of space-frequency vector pairs constructed in two polarization directions separately by using the L0 spatial domain vectors and the M0 frequency domain vectors; and
K0 represents a sum of quantities of space-frequency vector pairs that are in the two polarization directions and that are for constructing the precoding vector.
