Abstract: This application provides an information transmission method and a communication apparatus, and relates to the communication field. A terminal device may indicate a first beam and a first moment by using first indication information, the terminal device measures at least one first reference signal based on second indication information, to obtain a second beam, and indicates the second beam by using third indication information, and the terminal device may receive first configuration information at a second moment. The second moment at which the terminal device receives the first configuration information is obtained based on the first moment. The first moment may be a future moment, that is, the terminal device may predict the first beam in advance. The second moment is not earlier than the first moment, and the second moment may also be a future moment.

Abstract: The method includes: An access network device performs first encoding on a channel state information-reference signal CSI-RS, to generate first information, where the CSI-RS is used to obtain channel state information CSI corresponding to a channel between the access network device and a terminal device; the access network device sends the first information to the terminal device over N radio frequency links, where N is a positive integer; the access network device receives third information from the terminal device, where the third information is generated by the terminal device after the terminal device performs second encoding on second information, and the second information is determined by the terminal device based on the first information and the CSI-RS; and the access network device performs first decoding on the third information, to generate the CSI, where the first decoding includes decoding corresponding to the first encoding.
