Abstract
Embodiments of the present invention disclose a communication method and a device. Configuration information indicating one or more spatial domain beam basis vector groups and Q thresholds is received from a network device, where the Q thresholds correspond one-to-one to spatial domain beam basis vectors in the one or more spatial domain beam basis vector groups. L spatial domain beam basis vectors are selected from a spatial domain beam basis vector group set. K frequency domain basis vectors are selected from a frequency domain basis vector set for each of the L spatial domain beam basis vectors.
