Abstract: A method for establishing a communication connection between a station (STA) and an access point (AP). The method includes: receiving, by the AP, request frames sent by N STAs to the AP, and after the AP receives the request frames sent by the N STAs, contending for a channel by the AP and sending one response frame to M STAs, where the response frame includes identifiers of the M STAs and M responses to the M STAs. Each of the identifiers of the M STAs corresponds to one of the M responses, wherein 2≦M≦N.

Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.

Abstract: This application provides a power state determining method and apparatus, to determine a power state of a first access point in a power save mode, to reduce power consumption of a transmit end and a receive end, and improve communication accuracy. In the method, an access point multi-link device determines a priority sequence of different operations when the first access point is in the power save mode, and determines the power state of the first access point. The operations include one or more of link disablement, an aperiodic wakeup request, and periodic target wakeup.

Abstract: A resource allocation method includes generating a first frame and sending the first frame. The first frame includes a plurality of user information fields. Each user information field of the plurality of user information fields includes one user identifier subfield and is used to allocate a resource to a user identified by the user identifier subfield. Two or more user information fields in the plurality of user information fields have corresponding values of corresponding user identifier subfields that are the same.

Abstract: A method includes: when data of a first service needs to be sent to a receive end, sending m indication frames to the receive end if a type of the first service is a target service type; receiving n trigger frames sent by the receive end based on the m indication frames; and each time one trigger frame is received, sending the data of the first service to the receive end by using a transmission resource indicated by the trigger frame.

Abstract: In an information transmission method, a receiving device receives a data frame from a sending device. The data frame occupies a transmission resource block, and includes RU allocation information. The receiving device determines indication information based on a location of a 160 MHz channel with more data tones of the transmission resource block and a resource block size indicated by the RU allocation information. The receiving device then determines a response resource block based on the indication information and the RU allocation information, and sends an acknowledgment frame for the data frame to the sending device on the response resource block.

Abstract: In an information transmission method, a sending device sends a data frame to a receiving device. The data frame occupies a transmission resource block, a bandwidth occupied by the transmission resource block is greater than 160 MHz, and the data frame comprises resource unit RU allocation information. The sending device determines indication information based on a resource block size indicated by the RU allocation information and a location of a 160 MHz channel within the bandwidth occupied by the transmission resource block, with the 160 MHz channel having more data tones in the transmission resource block. The sending device determines a response resource block based on the indication information and the RU allocation information, and then receives an acknowledgment frame for the data frame from the receiving device on the response resource block.

Abstract: This application provides a communication method, an access network device, a terminal device, and a core network device. In a process in which the terminal device is handed over from a first access network device to a second access network device, the second access network device learns of first service progress of the first access network device based on a first sequence number of a data packet forwarded by the first access network device, without introducing additional progress exchange information between the two access network devices.

Abstract: A non-AP MLD or a first STA in the non-AP MLD generates a first frame. The first frame includes indication information for indicating padding duration for a channel switch delay in an initial control frame. The padding duration is determined based on duration of a control response frame. The non-AP MLD or the first STA or another STA in the non-AP MLD transmits the first frame. An AP MLD or a first AP or another AP in the AP MLD receives the first frame. The AP MLD or the first AP determines the padding duration of the initial control frame based on the indication information.
