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 that allow retransmitted MPDUs with different retransmission versions (RVs) to be transmitted in a same transmission process. The communication method and apparatus may be applied to a data retransmission process between any two nodes in a Wi-Fi system. In the method, when a PPDU sent by a first node includes one or more retransmitted MPDUs, the first node may include RV indication information in the PPDU to indicate an RV of each retransmitted MPDU, so that a second node can properly receive each retransmitted MPDU based on the RV indication information.
