Abstract: A transmission method is applied to a tunneled direct link setup (TDLS) such that different stations (STAs) associated with a same multiple basic service set identifier (BSSID) set communicate with each other based on the TDLS, to implement point-to-point communication. In the method, a first STA sends a first radio frame. The first radio frame includes initiator address information, responder address information, and a first BSSID. The first BSSID is in the multiple BSSID set including a BSSID of a basic service set (BSS) in which the first STA is located. The first STA receives a second radio frame. The second radio frame is a response frame of the first radio frame.

Abstract: This application relates to the wireless communications field, for example, is applicable to a wireless local area network supporting the 802.11be standard, and in particular, to a PPDU uplink bandwidth indication method and a related apparatus. The method includes: An AP generates and sends a trigger frame. The trigger frame carries first indication information, where the first indication information directly indicates or jointly indicates an EHT TB PPDU bandwidth or an uplink PPDU total transmission bandwidth. The trigger frame carries second indication information, where the second indication information indicates distribution of an HE TB PPDU and/or an EHT TB PPDU in the uplink PPDU total transmission bandwidth, or directly indicate whether an EHT station transmits an HE TB PPDU or an EHT TB PPDU.

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: This application provides a communication method and apparatus, to support a case in which a number of segments is greater than 8 or a case in which a size of an EHT compressed beamforming/channel quality indication report is greater than 91632 bytes. The communication method and apparatus may be applied to a Wi-Fi system. The method includes: A first device sends a first frame to a second device, and receives an EHT compressed beamforming/channel quality indication report from the second device. The first frame is used to request one or more of N segments of the extremely high throughput EHT compressed beamforming/channel quality indication report, and N is an integer greater than 8.

Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.
