Abstract: A terminal device obtains M channel estimation results. The terminal device jointly compresses the M channel estimation results by using a first encoder network, to obtain N pieces of compressed information and first state information, where the first state information represents downlink channel information, the downlink channel information includes information about downlink channels corresponding to the M channel estimation results, and the first state information is used to determine next input information of the first encoder network. The terminal device sends the N pieces of compressed information to an access network device. Downlink channels are correlated in time domain. When compressed information is obtained, in addition to a current downlink channel, a historical downlink channel is also referenced.

Abstract: This disclosure provides an information transmission method and an apparatus. A first device receives N pieces of first node information from a second device, so that a first artificial intelligence model can be determined based on the N pieces of first node information and first link information, in other words, a structure of the first artificial intelligence model can be reconstructed. According to the method, when the second device indicates an artificial intelligence model to the first device, node information of a node and a connection relationship between nodes may be separately indicated. In addition, if the connection relationship between the nodes in the artificial intelligence model is a serial structure, the first link information may not be indicated, and only the node information is indicated, so that representation and transmission overheads of the artificial intelligence model can be reduced.
