Claim 20:
21. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a program for execution by at least one processor to:
receive configuration information from a network device, wherein the configuration information indicates one or more spatial domain beam basis vector groups and Q thresholds, and the Q thresholds correspond one-to-one to spatial domain beam basis vectors in the one or more spatial domain beam basis vector groups;
select L spatial domain beam basis vectors from a spatial domain beam basis vector group set, the spatial domain beam basis vector group set comprising the one or more spatial domain beam basis vector groups;
select K frequency domain basis vectors from a frequency domain basis vector set for each of the L spatial domain beam basis vectors;
determine M spatial-frequency combination coefficient vectors based on the L spatial domain beam basis vectors, the K frequency domain basis vectors corresponding to each of the L spatial domain beam basis vectors, and a target precoding vector, wherein one spatial-frequency combination coefficient vector corresponds to one spatial domain beam basis vector, the spatial-frequency combination coefficient vector corresponding to the spatial domain beam basis vector satisfies a restriction rule, and the restriction rule is associated with a threshold corresponding to the spatial domain beam basis vector; and
send amplitudes and phases of spatial-frequency combination coefficients in the M spatial-frequency combination coefficient vectors to the network device.
