Abstract: This application relates to the communication field, and in particular, to a communication method and apparatus applicable to a multi-link device. The approach generates, by a first access point (AP) of a first access point multi-link device (AP MLD), first information that indicates whether a key basic service set (BSS) parameter corresponding to at least one AP of the first AP MLD changes. In turn, the first AP sends the first information to a first station multi-link device (STA MLD).

Abstract: This application relates to a communication method, a communication device, and a computer-readable storage medium. In the communication method, a second device receives a third protocol data unit from a first device. The third protocol data unit includes a second frame, and the second frame indicates that a first time period in a transmission opportunity of the first device is allocated for data transmission of the second device. The second device transmits a fourth protocol data unit to a third device within the first time period. A duration field in the fourth protocol data unit is set, so that a basic network allocation vector associated with the fourth device is 0 when the first time period ends. In this way, the fourth device can respond to triggering, thereby improving system efficiency.

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.

Abstract: A negotiation method for an operating mode, an initiator, a receiver, a chip system, a computer-readable storage medium, and a functional entity are disclosed. In operating mode (OM) negotiation, the initiator transmits an operating mode indication (OMI) to the responder. The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.
