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: The present disclosure relates to a channel access method and a channel access apparatus. In an example method, a first node obtains network status information in a target period. The network status information includes a first time segment and a second time segment. The first node inputs the network status information into a target neural network, to obtain a first prediction value and a second prediction value. The first node sends a to-be-sent packet to a second node through the shared channel in response to determining that the first prediction value is greater than the second prediction value.

Abstract: This application provides communication methods, apparatuses, and computer-readable storage media. In an example, a value of a specific element of a first access point (AP) (or a second AP) is reused in a management frame, to indicate specific elements of a plurality of APs in a multiple basic service set identifier (BSSID) set to which the first AP (or the second AP) belongs. The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.

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.
