Abstract: Embodiments of the present application provide a channel state information feedback method, device, and system. The method includes: generating an uplink signal, where the uplink signal carries information for identifying multiple codewords and weights of the codewords; and transmitting the uplink signal to a base station (BS), so that the base station estimates a downlink channel based on the multiple codewords and weight information of the codewords in the uplink signal. In the embodiments of the present application, a user equipment UE side reports multiple codewords and weight information of the multiple codewords. This can resolve a problem in the prior art that precision of downlink channel estimation performed by a BS side is relatively low because only a single codeword is reported, and can effectively enhance precision indicated by channel information, without increasing complexity of a codebook design and implementation.

Abstract: This application provides an intelligent component update method and a communication apparatus. A transmitting end sends indication information about one or more intelligent components to a receiving end. The indication information indicates a to-be-updated intelligent component of the transmitting end and/or a to-be-updated intelligent component of the receiving end. The to-be-updated intelligent component of the transmitting end belongs to a first intelligent module, and the to-be-updated intelligent component of the receiving end belongs to a second intelligent module. Based on the indication information, a to-be-updated indication can be performed for one or more intelligent components in an intelligent module, so that update efficiency and reliability of the intelligent module can be improved without affecting learning performance of the intelligent module, and update costs and system resource waste can be reduced.
