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.

Abstract: Embodiments of this application provide a data transmission method and apparatus and a storage medium. The method includes: After obtaining a first identifier and a second identifier that uniquely identify a first device, the first device scrambles, by using the first identifier, checked data obtained through CRC check. After performing channel coding on to-be-transmitted data and scrambled checked data, the first device scrambles, by using the second identifier, coded data obtained through channel coding, and finally sends scrambled data. In this way, after receiving the scrambled data, a second device may perform descrambling by using the second identifier, and then perform CRC check, to determine whether the received data is correct and determine the first identifier of the first device.
