Abstract: An intelligent model training method and apparatus. A plurality of participating nodes jointly train an intelligent model. This method is performed by one of the plurality of participating nodes, and the method includes: performing a Kth time of model training on the intelligent model to obtain first gradient information; and sending first synthetic gradient information to a central node, where the first synthetic gradient information includes synthetic information of the first gradient information and residual gradient information, and the residual gradient information represents a residual estimate of synthetic gradient information that is not transmitted to the central node before the Kth time of model training, where K is a positive integer.

Abstract: Example encoding/decoding methods, communication apparatus, and systems are provided. One example encoding method includes encoding first data by using an encoding model, to obtain N pieces of encoded data, where N is an integer greater than 2. De-correlation is performed on the N pieces of encoded data to obtain N pieces of de-correlated encoded data, where a part or all of the N pieces of de-correlated encoded data may be for determining second data, the second data is for restoring third data, and the third data is the first data, or an approximation degree between the third data and the first data is greater than a specified threshold The N pieces of de-correlated encoded data are sent.

Abstract: A communications method and device, to reduce service interruption time and signaling overheads that are generated when an access point that provides a communication service for a station changes because the station moves or changes a direction. First frames sent by different access points in an access point set to a station include a same sending address. In this way, when the station moves or changes a direction, the access point that provides the communication service for the station changes from one access point in the access point set to another access point. Because first frames sent by access points in the access point set include a same sending address, the station may consider the access point set as one access point.

Abstract: This application provides an information indication method and an apparatus. In this application, a sending apparatus generates and sends a first frame, the first frame includes at least one piece of sub-time resource indication information, and each piece of sub-time resource indication information is in a one-to-one correspondence with one of at least one response apparatus. In addition, each piece of sub-time resource indication information includes a time resource at which the corresponding response apparatus sends feedback information for the first frame to the sending apparatus and a time resource at which the sending apparatus sends acknowledgment information for the feedback information to the corresponding response apparatus, so that the at least one response apparatus and the sending apparatus that sends the first frame can simultaneously perform beamforming training, thereby improving effectiveness of beamforming training performed on the sending apparatus and the at least one response apparatus.
