Abstract
A channel state information processing method and a communication apparatus. The method includes obtaining CSI information of a channel, where the CSI information includes an N-dimensional antenna domain coefficient, and N is an integer greater than 1; performing a beam domain transformation on the CSI information based on an array response feature, to obtain first CSI transformation information that includes an N-dimensional beam domain coefficient; performing a cluster sparse domain transformation on the first CSI transformation information based on a cluster sparse transformation basis, to obtain second CSI transformation information that includes an N-dimensional cluster sparse domain coefficient and the cluster sparse transformation basis is determined based on a channel prior statistical feature of the channel; and sending quantized values of L cluster sparse domain coefficients in the N-dimensional cluster sparse domain coefficient to a second communication apparatus, where Lis a positive integer less than N.
