Abstract: This application provides communication methods, apparatus and systems. In an example method, a first station (STA) of a station multi-link device (STA MLD) sends a request frame to an access point multi-link device (AP MLD), wherein the request frame is used to request to establish single-link communication, and an address 2 field in the request frame is set to a media access control (MAC) address of the STA MLD. The first STA receives a response frame from the AP MLD, wherein the response frame indicates that the single-link communication is successfully established. The first STA performs air interface transmission with the AP MLD according to the single-link communication.

Abstract: A communication method is applied to a wireless local area network in an enhanced multi-link single radio (EMLSR) mode. When an enhanced multi-link single radio (EMLSR) non-access point multi-link device (non-AP MLD) finds that states of all or some links of the EMLSR non-AP MLD change, the EMLSR non-AP MLD sends a frame on any available link. The frame carries indication information indicating an available link or a link whose state changes in the EMLSR non-AP MLD. Alternatively, the frame may carry another piece of indication information indicating that a state of a link has changed. An access point multi-link device (AP MLD) refrains from sending a signal to the EMLSR non-AP MLD on an unavailable link of the EMLSR non-AP MLD.

Abstract: A communication method includes a first communication device that sends, to a second communication device, a physical layer protocol data unit (PPDU) including indication information and M link adaptation blocks, where the indication information indicates a resource used for link adaptation, the M link adaptation blocks use different transmission parameters, and the resource is used to transmit the M link adaptation blocks. The second communication device returns, to the first communication device, a feedback result determined based on a measurement result corresponding to the M link adaptation blocks, so that the first communication device sends, based on the feedback result, a PPDU used for data transmission. Hence, the two communication devices complete link adaptation through one interaction, and do not need to perform a plurality of interactions.

Abstract: A method and an apparatus are provided. The method includes: generating, by an access point (AP), a first frame including P station information fields, each of which corresponds to one resource unit (RU) allocated to a first station (STA), wherein P is a positive integer greater than 1, each station information field further includes end indication information, which indicates whether the station information field is the last station information field in the P station information fields. The AP may allocate P RUs to the first STA, and indicate the P RUs to the first STA through the P station information fields in the first frame. According to the application, a resource allocation manner of the AP can be more flexible, a frequency selective gain of an OFDMA system can be effectively improved, and a system capacity can be increased.

Abstract: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.
