  • Publication number: 20240129758
    Abstract: In the method, an access point AP receives action information separately reported by N stations STAs, where N pieces of action information are used to determine a training result of a first neural network of each STA, and N is a positive integer. The AP determines the training result of the first neural network of each STA based on the N pieces of action information, and sends the training result of the first neural network of each STA to the corresponding STA. The training result of the first neural network of each STA is determined based on the action information reported by the N STAs, instead of only the action information of the STA. This can improve a prediction capability of the first neural network, help improve a capability of each STA to predict channel access behavior of another STA, and improve a system throughput and reduce a communication latency.
