1. A method for transmitting channel state information, comprising:
constructing, by a first device, a training set of channel state information indicator model, wherein the channel state information indicator model is used by the first device and a second device to transmit channel state information,
sample structures of several samples comprised in the training set are determined according to an M*N matrix structure, each of M rows of the matrix structure corresponds to a plurality of subcarriers in a frequency domain or corresponds to a preset duration in a time domain, each of N columns of the matrix structure corresponds to at least one antenna in a spatial domain or corresponds to a preset angle in the spatial domain, and each value in the matrix structure represents a channel quality in the corresponding frequency domain and spatial domain, or represents a channel quality in the corresponding time domain and spatial domain, and M and N are positive integers.
