1. An encoding method for channel state information (CSI), performed by a user equipment (UE), the method comprising:
encoding, based on a first target CSI compression encoder, a target CSI matrix in a delay domain and an angle domain, to generate a compressed encoded value, wherein the first target CSI compression encoder comprises N composite convolution layers and one fully-connected layer, each composite convolution layer comprises a delay-domain convolution step and an angle-domain convolution step, and the delay-domain convolution step of a first composite convolution layer in the N composite convolution layers is smaller than the angle-domain convolution step of the first composite convolution layer in the N composite convolution layers, where N is a positive integer.
