Abstract: The embodiments of the present disclosure provide an error recovery method, an access point device, a station device, and a system thereof. The error recovery method includes: transmitting a data frame to a station allowed to enter a power save mode, where the data frame indicates the end of data transmission; and retransmitting the data frame during a current transmission opportunity period if no acknowledgement frame returned by the station in response to the data frame is received. Based on the above technical solution, the access point retransmits the data frame directly during the current transmission opportunity period and there is no need to contend for a new transmission opportunity period to perform the error recovery, thereby speeding up the error recovery and reducing the error recovery delay, thereby increasing the error recovery efficiency, saving the network resources, and improving the quality of service.

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: Embodiments of this application provide an information indication method and a communication apparatus. The method is applied to a wireless local area network system that supports various IEEE 802.11 protocols such as the 802.11bf series protocols. The method includes: generating a PPDU, where the PPDU includes sensing indication information, the sensing indication information indicates that the PPDU is a PPDU used for sensing measurement, and the PPDU is a directional multi-gigabit DMG single carrier mode PPDU, an enhanced directional multi-gigabit EDMG single carrier mode PPDU, or an EDMG orthogonal frequency division multiplexing mode PPDU; and sending the PPDU. In this manner, a sensing PPDU and a non-sensing PPDU in a communication system can be distinguished, so that a receive end optimizes sensing performance.

Abstract: Embodiments of the present disclosure disclose example data communication methods and apparatuses. One set of operations performed by the example solutions includes sending a preset frame to an access point (AP) associated with a data communication apparatus, wherein the data communication apparatus and the AP belong to a first basic service set (BSS) having a first BSS identifier, and the preset frame comprises a second BSS identifier that identifies a second BSS. A physical layer protocol data unit (PPDU) is sent, wherein the PPDU comprises a target BSS identifier. Receiving a frame from the AP is stopped in response to the target BSS identifier being the same as the second BSS identifier and different from the first BSS identifier, as well as a preset condition being met.

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: 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.
